We appreciate your interest and effort to help improve our database. + +Example PR: [click here](https://github.com/OTFCG/Awesome-Game-Analysis/pull/12). + +## Step 0: Gather Game Information + +Before you begin contributing, make sure you've collected all the required game information. This includes: + +- The title of the game +- The game's developer(studio) +- The engine used to develop the game +- The year the game was released +- Any links relevant to the game's analysis + +Such information can be obtained from reliable sources like official game websites, developer interviews, or public resources like Wikipedia. + +## Step 1: Add the Game Information + +After you've collected all the necessary data, add it to the `data/games.toml` file following the provided format. Please append this information to the end of the file. + +The required format is as follows: + +```toml +["Game Name"] +Developer = "Developer" +Engine = "Engine Used" +Year = "Year of Release" +Analysis = [ + ["Title of Link 1", "https://link1.com"], + ["Title of Link 2", "https://link2.com"], + .... +] +``` + +Replace the placeholders with the appropriate game information. For the Analysis section, list all the analysis links you've obtained in the same way. + +## Step 2 (optional): Test README.md File Generation + +Once you've added the game information to the `data/games.toml` file, it's good practice to check if the `README.md` file generation works correctly. + +Run the following command in the `scripts/toml_markdown.py` script: + +``` bash +$ python scripts/toml_markdown.py -i data/games.toml -t toml --readme +``` + +This command converts the `data/games.toml` file into a `README.md` file. Note that the file conversion is automatically executed by our Continuous Integration (CI) system. + + +## Step 3: Create a Pull Request + +Finally, create a pull request with the changes you made to the `data/games.toml` file. Please provide a brief yet comprehensive description of the changes you've made (e.g., new game entries, typo corrections) in the pull request. + +We appreciate your contribution and efforts to enhance our game information repository.

although the build process can be done on your Real PC.
+> VMWare/Hyper-V are recommended to run the VM due to their performance. + +## Prerequisite Setup +1. Install DirectX SDK June 2010 and 7-Zip +2. Install Visual Studio 2012 + - Uncheck all optional components in the installer **except "Microsoft Foundation Classes for C++"** to save space, none of them are needed for the build. +3. Install Update 4 for Visual Studio 2012 +4. Install Incredibuild 4.0 (Only needed for compiling shaders and scripts) + - If you encounter the error that the installer is "Blocked by your administrator", follow these steps: + 1. Hold Shift and right click the `incredibuild4_0.exe` file, select "Copy as path" + 2. Open Command Prompt as Administrator + 3. Paste the path and press Enter + - Select to install "Incredibuild Agent", "Incredibuild Coordinator", and the extension for Visual Studio +5. Install OpenIV +6. Install Miscellaneous Files +8. Create X:\ Drive by following the steps at the bottom + 1. Open Command Prompt + 2. Create a new folder called "GTA" to the Desktop or anywhere that you want. + 3. Run `net use X: \\localhost\c$\ /persistent:yes` + - Example: `net use X: \\localhost\c$\Users\abcd\Desktop\GTA /persistent:yes` +9. Create the folder `X:\gta5` and copy all folders from `GTAVSP.7z\GTA V Source` into it + - By the end, you should have the folders `X:\gta5\src`, `X:\gta5\script`, and `X:\gta5\tools_ng`. If the paths are different or some folders are missing, try re-extracting or moving as needed. +10. Right click the folder `X:\gta5`, select "Properties", uncheck "Read-only", click Apply then OK +11. Copy all folders in `dll_patches.zip` to `X:\gta5\tools_ng\bin`, make sure to overwrite when copying +12. Open Command Prompt as Administrator and run the following commands, then close: +```batch +setx /m RS_TOOLSROOT X:\gta5\tools_ng +setx /m DXSDK_DIR "C:\Program Files (x86)\Microsoft DirectX SDK (June 2010)" +setx /m RS_CODEBRANCH X:\gta5\src\dev_ng +setx /m RS_PROJECT gta5 +``` +12. To ensure changes are finalized, restart build machine. + +## Patching The Source Code +1. Open `rush_patches-master.zip` +2. Copy `game` and `rage` folders to `X:\gta5\src\dev_ng`, make sure to overwrite when copying +3. (OPTIONAL) To skip launcher requirement for running the game, copy `game` and `rage` folders from `OPTIONAL_FIXES` to the same folder + +## Building The Game Binary +1. Run `X:\gta5\src\dev_ng\game\VS_Project\load_sln_unity_2012.bat` + - If prompted with "How do you want to open this file?", check "Always use this app to open .sln files" and click OK. +2. Once the solution loads, open the dropdown menu that says "Debug" at the top, select "Configuration Manager" +3. Change "Active Solution Platform" to "x64" and close the configuration window +4. Hold Ctrl key and click all projects under "GameLibs" and "Rage", right-click and select "Properties" +5. In the "Configuration" dropdown, select "All Configurations" +6. Select `C/C++ > All options`, under "Look for options or switches", search "err" and set "Treat Warnings as Errors" to "No (/WX-)", then click "Apply" and "OK" + - For faster compiles, search "mul" and set "Multiprocessor Compilation" to "Yes (/MP)". + - If you get the error `C1060: Compiler is out of heap space` during build, come back to the above setting and turn it off. +7. Right-click the "game" project and select "Properties" and do step 5 again +8. Change build the type at the top of the window from "Debug" to "BankRelease" +9. At the top of the window, select `Build > Build Solution` and wait for build to finish. +10. Copy output binary to game folder. + +> [!NOTE] +> Building shaders and scripts can be skipped using the prebuilt files above. These steps are here to allow modding or for those who prefer to build from source as much as possible. + +## Building Shaders +1. Under "Shaders", right click the "shaders_rc" project and click "Build" + - If you building in "BankRelease", Dont forget to build shaders with "Release Win32 4.0" in **Configuration Manager**. + - Also, the same thing needs to apply to "shaders_dependency", Change "Debug" to "Release" in **Configuration Manager** + - **If you compiling with Debug, then ignore the steps at the top and continue reading the tutorial.** +2. (OPTIONAL) Build low quality shaders + 1. Right click the "shaders_rc" project and click "Properties" + 2. Select `Configuration Properties > NMake` + 3. Under "General", change all command lines from ending with `win32_40.bat` to ending with `win32_40_lq.bat`, then click "Apply" and "OK" + 4. Rebuild shaders + 3. Copy `X:\gta5\titleupdate\dev_ng\common` to game directory + +## Building Game Scripts +1. Open Command Prompt +2. Run the following commands: +```batch +X: +cd X:\gta5\src\dev_ng +setenv +cd ..\..\tools_ng\bin\RageScriptEditor +ragScriptEditor +``` +3. In the editor, select `File > Open Project` and open `X:\gta5\script\dev_ng\singleplayer\GTA5_SP.scproj` +4. Select `Compiling > Intellibuild > Build Project` + +## Patching Game Assets +1. Run OpenIV, select "Windows" +2. Select the game folder and click "Continue" +3. Open `GTA V\update\update2.rpf\x64\levels\gta5\script` +4. Click the "Edit mode" button, and copy `X:\gta5\titleupdate\dev_ng\x64\levels\gta5\script\script.rpf` to the OpenIV window +5. (OPTIONAL) Fix Story Mode + 1.

Change the value of `51000` to `53000` + 5. Click "Save" +6. Close OpenIV +7. From `rush_patches-master.zip`, copy all files in the `ARCHIVEFIX` folder to a separate location +8. Open `\update`, and drag `update.rpf` and `update2.rpf` onto `ArchiveFix.exe` +9. Close both windows + +## Running The Game +1. In the game directory, create a file named `launch.bat` and add these contents: +```batch +cd %~dp0 +game_win64_bankrelease.exe -noSocialClub -nokeyboardhook -nonetlogs +``` +2. (OPTIONAL) Add additional arguments: + - `-kbgame` - Start game with game keyboard enabled. + - `-output` - Show console log of game. + - `-rag` - Enable support for RAG, the internal game debugging tool. + - `-ragUseOwnWindow` - Use it with `-rag` parameter to make game run outside of RAG Render Window. + - `-DoReleaseStartup` - Start real Story Mode on launch, Ignore if it says unknown parameter/command. + - If you dont type this parameter, you will spawned in a random location as a random character with a random clothes. + - `-sc_DisableForbiddenVehicleRemoval` - This parameter allows DLC and Other Cars without getting removed. + - Additional standard game arguments can be added as well. + - [Here is the all the arguments list](misc/LAUNCHPARAMS_GTAV.txt) +3. (OPTIONAL) Launch RAG with the following commands in Command Prompt +```batch +X: +cd X:\gta5\src\dev_ng +setenv +cd ..\..\tools_ng\bin\rag +rag +``` +4. (OPTIONAL) If your game is from Steam, Copy [Goldberg](https://gitlab.com/Mr_Goldberg/goldberg_emulator/-/jobs/4247811310/artifacts/download) patch into game directory, make sure to overwrite +5. Run `launch.bat` + +## BankRelease & Debug Build Controls + +[Full list dumped from game files](/misc/Keyboard_Overview.pdf) + +**Here is the partial list:** +``` +Legend: +LCTRL -- Left control. +RCTRL -- Right control. +LALT - Left alt. +RALT - Right alt. +LSHIFT - Left shift +RSHIFT - Right shift. + +Main keybinds: +CTRL + TAB -> Switch between game keyboards.

The UI can be highly dynamic, there are no construction or + destruction steps, less superfluous data retention on your side, less state duplication, less state synchronization, fewer bugs. + - Call and read ImGui::ShowDemoWindow() for demo code demonstrating most features. + - The library is designed to be built from sources. Avoid pre-compiled binaries and packaged versions. See imconfig.h to configure your build. + - Dear ImGui is an implementation of the IMGUI paradigm (immediate-mode graphical user interface, a term coined by Casey Muratori). + You can learn about IMGUI principles at http://www.johno.se/book/imgui.html, http://mollyrocket.com/861 & more links in Wiki. + - Dear ImGui is a "single pass" rasterizing implementation of the IMGUI paradigm, aimed at ease of use and high-performances. + For every application frame, your UI code will be called only once. This is in contrast to e.g. Unity's implementation of an IMGUI, + where the UI code is called multiple times ("multiple passes") from a single entry point. There are pros and cons to both approaches. + - Our origin is on the top-left. In axis aligned bounding boxes, Min = top-left, Max = bottom-right. + - This codebase is also optimized to yield decent performances with typical "Debug" builds settings. + - Please make sure you have asserts enabled (IM_ASSERT redirects to assert() by default, but can be redirected). + If you get an assert, read the messages and comments around the assert. + - C++: this is a very C-ish codebase: we don't rely on C++11, we don't include any C++ headers, and ImGui:: is a namespace. + - C++: ImVec2/ImVec4 do not expose math operators by default, because it is expected that you use your own math types. + See FAQ "How can I use my own math types instead of ImVec2/ImVec4?" for details about setting up imconfig.h for that. + However, imgui_internal.h can optionally export math operators for ImVec2/ImVec4, which we use in this codebase. + - C++: pay attention that ImVector<> manipulates plain-old-data and does not honor construction/destruction (avoid using it in your code!). + + + HOW TO UPDATE TO A NEWER VERSION OF DEAR IMGUI + ---------------------------------------------- + - Overwrite all the sources files except for imconfig.h (if you have modified your copy of imconfig.h) + - Or maintain your own branch where you have imconfig.h modified as a top-most commit which you can regularly rebase over "master". + - You can also use '#define IMGUI_USER_CONFIG "my_config_file.h" to redirect configuration to your own file. + - Read the "API BREAKING CHANGES" section (below). This is where we list occasional API breaking changes. + If a function/type has been renamed / or marked obsolete, try to fix the name in your code before it is permanently removed + from the public API. If you have a problem with a missing function/symbols, search for its name in the code, there will + likely be a comment about it. Please report any issue to the GitHub page! + - To find out usage of old API, you can add '#define IMGUI_DISABLE_OBSOLETE_FUNCTIONS' in your configuration file. + - Try to keep your copy of Dear ImGui reasonably up to date. + + + GETTING STARTED WITH INTEGRATING DEAR IMGUI IN YOUR CODE/ENGINE + --------------------------------------------------------------- + - Run and study the examples and demo in imgui_demo.cpp to get acquainted with the library. + - In the majority of cases you should be able to use unmodified backends files available in the backends/ folder. + - Add the Dear ImGui source files + selected backend source files to your projects or using your preferred build system. + It is recommended you build and statically link the .cpp files as part of your project and NOT as a shared library (DLL). + - You can later customize the imconfig.h file to tweak some compile-time behavior, such as integrating Dear ImGui types with your own maths types. + - When using Dear ImGui, your programming IDE is your friend: follow the declaration of variables, functions and types to find comments about them. + - Dear ImGui never touches or knows about your GPU state. The only function that knows about GPU is the draw function that you provide. + Effectively it means you can create widgets at any time in your code, regardless of considerations of being in "update" vs "render" + phases of your own application. All rendering information is stored into command-lists that you will retrieve after calling ImGui::Render(). + - Refer to the backends and demo applications in the examples/ folder for instruction on how to setup your code. + - If you are running over a standard OS with a common graphics API, you should be able to use unmodified imgui_impl_*** files from the examples/ folder. + + + HOW A SIMPLE APPLICATION MAY LOOK LIKE + -------------------------------------- + EXHIBIT 1: USING THE EXAMPLE BACKENDS (= imgui_impl_XXX.cpp files from the backends/ folder). + The sub-folders in examples/ contain examples applications following this structure. + + // Application init: create a dear imgui context, setup some options, load fonts + ImGui::CreateContext(); + ImGuiIO& io = ImGui::GetIO(); + // TODO: Set optional io.ConfigFlags values, e.g. 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableKeyboard' to enable keyboard controls. + // TODO: Fill optional fields of the io structure later. + // TODO: Load TTF/OTF fonts if you don't want to use the default font. + + // Initialize helper Platform and Renderer backends (here we are using imgui_impl_win32.cpp and imgui_impl_dx11.cpp) + ImGui_ImplWin32_Init(hwnd); + ImGui_ImplDX11_Init(g_pd3dDevice, g_pd3dDeviceContext); + + // Application main loop + while (true) + { + // Feed inputs to dear imgui, start new frame + ImGui_ImplDX11_NewFrame(); + ImGui_ImplWin32_NewFrame(); + ImGui::NewFrame(); + + // Any application code here + ImGui::Text("Hello, world!"); + + // Render dear imgui into screen + ImGui::Render(); + ImGui_ImplDX11_RenderDrawData(ImGui::GetDrawData()); + g_pSwapChain->Present(1, 0); + } + + // Shutdown + ImGui_ImplDX11_Shutdown(); + ImGui_ImplWin32_Shutdown(); + ImGui::DestroyContext(); + + EXHIBIT 2: IMPLEMENTING CUSTOM BACKEND / CUSTOM ENGINE + + // Application init: create a dear imgui context, setup some options, load fonts + ImGui::CreateContext(); + ImGuiIO& io = ImGui::GetIO(); + // TODO: Set optional io.ConfigFlags values, e.g. 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableKeyboard' to enable keyboard controls. + // TODO: Fill optional fields of the io structure later. + // TODO: Load TTF/OTF fonts if you don't want to use the default font. + + // Build and load the texture atlas into a texture + // (In the examples/ app this is usually done within the ImGui_ImplXXX_Init() function from one of the demo Renderer) + int width, height; + unsigned char* pixels = NULL; + io.Fonts->GetTexDataAsRGBA32(&pixels, &width, &height); + + // At this point you've got the texture data and you need to upload that to your graphic system: + // After we have created the texture, store its pointer/identifier (_in whichever format your engine uses_) in 'io.Fonts->TexID'. + // This will be passed back to your via the renderer.

For more advanced uses, you may want to read from: + - io.NavActive: true when a window is focused and it doesn't have the ImGuiWindowFlags_NoNavInputs flag set. + - io.NavVisible: true when the navigation cursor is visible (and usually goes false when mouse is used). + - or query focus information with e.g. IsWindowFocused(ImGuiFocusedFlags_AnyWindow), IsItemFocused() etc. functions. + Please reach out if you think the game vs navigation input sharing could be improved. + - Gamepad: + - Application: Set io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad to enable. + - Backend: Set io.BackendFlags |= ImGuiBackendFlags_HasGamepad + call io.AddKeyEvent/AddKeyAnalogEvent() with ImGuiKey_Gamepad_XXX keys. + For analog values (0.0f to 1.0f), backend is responsible to handling a dead-zone and rescaling inputs accordingly. + Backend code will probably need to transform your raw inputs (such as e.g. remapping your 0.2..0.9 raw input range to 0.0..1.0 imgui range, etc.). + - Internally: NewFrame() will automatically fill io.NavInputs[] based on backend's io.AddKeyEvent() + io.AddKeyAnalogEvent() calls. + - BEFORE 1.87, BACKENDS USED TO WRITE DIRECTLY TO io.NavInputs[]. This is going to be obsoleted in the future. Please call io functions instead! + - You can download PNG/PSD files depicting the gamepad controls for common controllers at: http://dearimgui.org/controls_sheets + - If you need to share inputs between your game and the Dear ImGui interface, the easiest approach is to go all-or-nothing, + with a buttons combo to toggle the target. Please reach out if you think the game vs navigation input sharing could be improved. + - Mouse: + - PS4/PS5 users: Consider emulating a mouse cursor with DualShock4 touch pad or a spare analog stick as a mouse-emulation fallback. + - Consoles/Tablet/Phone users: Consider using a Synergy 1.x server (on your PC) + uSynergy.c (on your console/tablet/phone app) to share your PC mouse/keyboard. + - On a TV/console system where readability may be lower or mouse inputs may be awkward, you may want to set the ImGuiConfigFlags_NavEnableSetMousePos flag. + Enabling ImGuiConfigFlags_NavEnableSetMousePos + ImGuiBackendFlags_HasSetMousePos instructs dear imgui to move your mouse cursor along with navigation movements. + When enabled, the NewFrame() function may alter 'io.MousePos' and set 'io.WantSetMousePos' to notify you that it wants the mouse cursor to be moved. + When that happens your backend NEEDS to move the OS or underlying mouse cursor on the next frame. Some of the backends in examples/ do that. + (If you set the NavEnableSetMousePos flag but don't honor 'io.WantSetMousePos' properly, imgui will misbehave as it will see your mouse moving back and forth!) + (In a setup when you may not have easy control over the mouse cursor, e.g. uSynergy.c doesn't expose moving remote mouse cursor, you may want + to set a boolean to ignore your other external mouse positions until the external source is moved again.) + + + API BREAKING CHANGES + ==================== + + Occasionally introducing changes that are breaking the API. We try to make the breakage minor and easy to fix. + Below is a change-log of API breaking changes only. If you are using one of the functions listed, expect to have to fix some code. + When you are not sure about an old symbol or function name, try using the Search/Find function of your IDE to look for comments or references in all imgui files. + You can read releases logs https://github.com/ocornut/imgui/releases for more details. + + - 2022/01/20 (1.87) - inputs: reworded gamepad IO. + - Backend writing to io.NavInputs[] -> backend should call io.AddKeyEvent()/io.AddKeyAnalogEvent() with ImGuiKey_GamepadXXX values. + - 2022/01/19 (1.87) - sliders, drags: removed support for legacy arithmetic operators (+,+-,*,/) when inputing text. This doesn't break any api/code but a feature that used to be accessible by end-users (which seemingly no one used). + - 2022/01/17 (1.87) - inputs: reworked mouse IO. + - Backend writing to io.MousePos -> backend should call io.AddMousePosEvent() + - Backend writing to io.MouseDown[] -> backend should call io.AddMouseButtonEvent() + - Backend writing to io.MouseWheel -> backend should call io.AddMouseWheelEvent() + - Backend writing to io.MouseHoveredViewport -> backend should call io.AddMouseViewportEvent() [Docking branch w/ multi-viewports only] + - 2022/01/10 (1.87) - inputs: reworked keyboard IO. Removed io.KeyMap[], io.KeysDown[] in favor of calling io.AddKeyEvent(). Removed GetKeyIndex(), now unecessary. All IsKeyXXX() functions now take ImGuiKey values. All features are still functional until IMGUI_DISABLE_OBSOLETE_KEYIO is defined. Read Changelog and Release Notes for details. + - IsKeyPressed(MY_NATIVE_KEY_XXX) -> use IsKeyPressed(ImGuiKey_XXX) + - IsKeyPressed(GetKeyIndex(ImGuiKey_XXX)) -> use IsKeyPressed(ImGuiKey_XXX) + - Backend writing to io.KeyMap[],io.KeysDown[] -> backend should call io.AddKeyEvent() + - Backend writing to io.KeyCtrl, io.KeyShift.. -> backend should call io.AddKeyEvent() with ImGuiKey_ModXXX values. *IF YOU PULLED CODE BETWEEN 2021/01/10 and 2021/01/27: We used to have a io.AddKeyModsEvent() function which was now replaced by io.AddKeyEvent() with ImGuiKey_ModXXX values.* + - one case won't work with backward compatibility: if your custom backend used ImGuiKey as mock native indices (e.g. "io.KeyMap[ImGuiKey_A] = ImGuiKey_A") because those values are now larger than the legacy KeyDown[] array. Will assert. + - inputs: added ImGuiKey_ModCtrl/ImGuiKey_ModShift/ImGuiKey_ModAlt/ImGuiKey_ModSuper values to submit keyboard modifiers using io.AddKeyEvent(), instead of writing directly to io.KeyCtrl, io.KeyShift, io.KeyAlt, io.KeySuper. + - 2022/01/05 (1.87) - inputs: renamed ImGuiKey_KeyPadEnter to ImGuiKey_KeypadEnter to align with new symbols. Kept redirection enum. + - 2022/01/05 (1.87) - removed io.ImeSetInputScreenPosFn() in favor of more flexible io.SetPlatformImeDataFn(). Removed 'void* io.ImeWindowHandle' in favor of writing to 'void* ImGuiViewport::PlatformHandleRaw'. + - 2022/01/01 (1.87) - commented out redirecting functions/enums names that were marked obsolete in 1.69, 1.70, 1.71, 1.72 (March-July 2019) + - ImGui::SetNextTreeNodeOpen() -> use ImGui::SetNextItemOpen() + - ImGui::GetContentRegionAvailWidth() -> use ImGui::GetContentRegionAvail().x + - ImGui::TreeAdvanceToLabelPos() -> use ImGui::SetCursorPosX(ImGui::GetCursorPosX() + ImGui::GetTreeNodeToLabelSpacing()); + - ImFontAtlas::CustomRect -> use ImFontAtlasCustomRect + - ImGuiColorEditFlags_RGB/HSV/HEX -> use ImGuiColorEditFlags_DisplayRGB/HSV/Hex + - 2021/12/20 (1.86) - backends: removed obsolete Marmalade backend (imgui_impl_marmalade.cpp) + example.

Prefer using ImGuiListClipper which can return non-contiguous ranges. Please open an issue if you think you really need this function. + - 2021/08/23 (1.85) - removed GetWindowContentRegionWidth() function. keep inline redirection helper. can use 'GetWindowContentRegionMax().x - GetWindowContentRegionMin().x' instead for generally 'GetContentRegionAvail().x' is more useful. + - 2021/07/26 (1.84) - commented out redirecting functions/enums names that were marked obsolete in 1.67 and 1.69 (March 2019): + - ImGui::GetOverlayDrawList() -> use ImGui::GetForegroundDrawList() + - ImFont::GlyphRangesBuilder -> use ImFontGlyphRangesBuilder + - 2021/05/19 (1.83) - backends: obsoleted direct access to ImDrawCmd::TextureId in favor of calling ImDrawCmd::GetTexID(). + - if you are using official backends from the source tree: you have nothing to do. + - if you have copied old backend code or using your own: change access to draw_cmd->TextureId to draw_cmd->GetTexID(). + - 2021/03/12 (1.82) - upgraded ImDrawList::AddRect(), AddRectFilled(), PathRect() to use ImDrawFlags instead of ImDrawCornersFlags. + - ImDrawCornerFlags_TopLeft -> use ImDrawFlags_RoundCornersTopLeft + - ImDrawCornerFlags_BotRight -> use ImDrawFlags_RoundCornersBottomRight + - ImDrawCornerFlags_None -> use ImDrawFlags_RoundCornersNone etc. + flags now sanely defaults to 0 instead of 0x0F, consistent with all other flags in the API. + breaking: the default with rounding > 0.0f is now "round all corners" vs old implicit "round no corners": + - rounding == 0.0f + flags == 0 --> meant no rounding --> unchanged (common use) + - rounding > 0.0f + flags != 0 --> meant rounding --> unchanged (common use) + - rounding == 0.0f + flags != 0 --> meant no rounding --> unchanged (unlikely use) + - rounding > 0.0f + flags == 0 --> meant no rounding --> BREAKING (unlikely use): will now round all corners --> use ImDrawFlags_RoundCornersNone or rounding == 0.0f. + this ONLY matters for hard coded use of 0 + rounding > 0.0f. Use of named ImDrawFlags_RoundCornersNone (new) or ImDrawCornerFlags_None (old) are ok. + the old ImDrawCornersFlags used awkward default values of ~0 or 0xF (4 lower bits set) to signify "round all corners" and we sometimes encouraged using them as shortcuts. + legacy path still support use of hard coded ~0 or any value from 0x1 or 0xF. They will behave the same with legacy paths enabled (will assert otherwise). + - 2021/03/11 (1.82) - removed redirecting functions/enums names that were marked obsolete in 1.66 (September 2018): + - ImGui::SetScrollHere() -> use ImGui::SetScrollHereY() + - 2021/03/11 (1.82) - clarified that ImDrawList::PathArcTo(), ImDrawList::PathArcToFast() won't render with radius < 0.0f. Previously it sorts of accidentally worked but would generally lead to counter-clockwise paths and have an effect on anti-aliasing. + - 2021/03/10 (1.82) - upgraded ImDrawList::AddPolyline() and PathStroke() "bool closed" parameter to "ImDrawFlags flags". The matching ImDrawFlags_Closed value is guaranteed to always stay == 1 in the future. + - 2021/02/22 (1.82) - (*undone in 1.84*) win32+mingw: Re-enabled IME functions by default even under MinGW. In July 2016, issue #738 had me incorrectly disable those default functions for MinGW. MinGW users should: either link with -limm32, either set their imconfig file with '#define IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCTIONS'. + - 2021/02/17 (1.82) - renamed rarely used style.CircleSegmentMaxError (old default = 1.60f) to style.CircleTessellationMaxError (new default = 0.30f) as the meaning of the value changed. + - 2021/02/03 (1.81) - renamed ListBoxHeader(const char* label, ImVec2 size) to BeginListBox(). Kept inline redirection function (will obsolete). + - removed ListBoxHeader(const char* label, int items_count, int height_in_items = -1) in favor of specifying size. Kept inline redirection function (will obsolete). + - renamed ListBoxFooter() to EndListBox(). Kept inline redirection function (will obsolete). + - 2021/01/26 (1.81) - removed ImGuiFreeType::BuildFontAtlas(). Kept inline redirection function. Prefer using '#define IMGUI_ENABLE_FREETYPE', but there's a runtime selection path available too. The shared extra flags parameters (very rarely used) are now stored in ImFontAtlas::FontBuilderFlags. + - renamed ImFontConfig::RasterizerFlags (used by FreeType) to ImFontConfig::FontBuilderFlags. + - renamed ImGuiFreeType::XXX flags to ImGuiFreeTypeBuilderFlags_XXX for consistency with other API. + - 2020/10/12 (1.80) - removed redirecting functions/enums that were marked obsolete in 1.63 (August 2018): + - ImGui::IsItemDeactivatedAfterChange() -> use ImGui::IsItemDeactivatedAfterEdit(). + - ImGuiCol_ModalWindowDarkening -> use ImGuiCol_ModalWindowDimBg + - ImGuiInputTextCallback -> use ImGuiTextEditCallback + - ImGuiInputTextCallbackData -> use ImGuiTextEditCallbackData + - 2020/12/21 (1.80) - renamed ImDrawList::AddBezierCurve() to AddBezierCubic(), and PathBezierCurveTo() to PathBezierCubicCurveTo(). Kept inline redirection function (will obsolete). + - 2020/12/04 (1.80) - added imgui_tables.cpp file! Manually constructed project files will need the new file added! + - 2020/11/18 (1.80) - renamed undocumented/internals ImGuiColumnsFlags_* to ImGuiOldColumnFlags_* in prevision of incoming Tables API. + - 2020/11/03 (1.80) - renamed io.ConfigWindowsMemoryCompactTimer to io.ConfigMemoryCompactTimer as the feature will apply to other data structures + - 2020/10/14 (1.80) - backends: moved all backends files (imgui_impl_XXXX.cpp, imgui_impl_XXXX.h) from examples/ to backends/. + - 2020/10/12 (1.80) - removed redirecting functions/enums that were marked obsolete in 1.60 (April 2018): + - io.RenderDrawListsFn pointer -> use ImGui::GetDrawData() value and call the render function of your backend + - ImGui::IsAnyWindowFocused() -> use ImGui::IsWindowFocused(ImGuiFocusedFlags_AnyWindow) + - ImGui::IsAnyWindowHovered() -> use ImGui::IsWindowHovered(ImGuiHoveredFlags_AnyWindow) + - ImGuiStyleVar_Count_ -> use ImGuiStyleVar_COUNT + - ImGuiMouseCursor_Count_ -> use ImGuiMouseCursor_COUNT + - removed redirecting functions names that were marked obsolete in 1.61 (May 2018): + - InputFloat (... int decimal_precision ...) -> use InputFloat (... const char* format ...) with format = "%.Xf" where X is your value for decimal_precision. + - same for InputFloat2()/InputFloat3()/InputFloat4() variants taking a `int decimal_precision` parameter. + - 2020/10/05 (1.79) - removed ImGuiListClipper: Renamed constructor parameters which created an ambiguous alternative to using the ImGuiListClipper::Begin() function, with misleading edge cases (note: imgui_memory_editor <0.40 from imgui_club/ used this old clipper API. Update your copy if needed). + - 2020/09/25 (1.79) - renamed ImGuiSliderFlags_ClampOnInput to ImGuiSliderFlags_AlwaysClamp. Kept redirection enum (will obsolete sooner because previous name was added recently). + - 2020/09/25 (1.79) - renamed style.TabMinWidthForUnselectedCloseButton to style.TabMinWidthForCloseButton. + - 2020/09/21 (1.79) - renamed OpenPopupContextItem() back to OpenPopupOnItemClick(), reverting the change from 1.77. For varieties of reason this is more self-explanatory. + - 2020/09/21 (1.79) - removed return value from OpenPopupOnItemClick() - returned true on mouse release on an item - because it is inconsistent with other popup APIs and makes others misleading. It's also and unnecessary: you can use IsWindowAppearing() after BeginPopup() for a similar result. + - 2020/09/17 (1.79) - removed ImFont::DisplayOffset in favor of ImFontConfig::GlyphOffset. DisplayOffset was applied after scaling and not very meaningful/useful outside of being needed by the default ProggyClean font. If you scaled this value after calling AddFontDefault(), this is now done automatically. It was also getting in the way of better font scaling, so let's get rid of it now! + - 2020/08/17 (1.78) - obsoleted use of the trailing 'float power=1.0f' parameter for DragFloat(), DragFloat2(), DragFloat3(), DragFloat4(), DragFloatRange2(), DragScalar(), DragScalarN(), SliderFloat(), SliderFloat2(), SliderFloat3(), SliderFloat4(), SliderScalar(), SliderScalarN(), VSliderFloat() and VSliderScalar(). + replaced the 'float power=1.0f' argument with integer-based flags defaulting to 0 (as with all our flags). + worked out a backward-compatibility scheme so hopefully most C++ codebase should not be affected. in short, when calling those functions: + - if you omitted the 'power' parameter (likely!), you are not affected. + - if you set the 'power' parameter to 1.0f (same as previous default value): 1/ your compiler may warn on float>int conversion, 2/ everything else will work. 3/ you can replace the 1.0f value with 0 to fix the warning, and be technically correct. + - if you set the 'power' parameter to >1.0f (to enable non-linear editing): 1/ your compiler may warn on float>int conversion, 2/ code will assert at runtime, 3/ in case asserts are disabled, the code will not crash and enable the _Logarithmic flag. 4/ you can replace the >1.0f value with ImGuiSliderFlags_Logarithmic to fix the warning/assert and get a _similar_ effect as previous uses of power >1.0f. + see https://github.com/ocornut/imgui/issues/3361 for all details. + kept inline redirection functions (will obsolete) apart for: DragFloatRange2(), VSliderFloat(), VSliderScalar(). For those three the 'float power=1.0f' version was removed directly as they were most unlikely ever used. + for shared code, you can version check at compile-time with `#if IMGUI_VERSION_NUM >= 17704`. + - obsoleted use of v_min > v_max in DragInt, DragFloat, DragScalar to lock edits (introduced in 1.73, was not demoed nor documented very), will be replaced by a more generic ReadOnly feature. You may use the ImGuiSliderFlags_ReadOnly internal flag in the meantime. + - 2020/06/23 (1.77) - removed BeginPopupContextWindow(const char*, int mouse_button, bool also_over_items) in favor of BeginPopupContextWindow(const char*, ImGuiPopupFlags flags) with ImGuiPopupFlags_NoOverItems. + - 2020/06/15 (1.77) - renamed OpenPopupOnItemClick() to OpenPopupContextItem(). Kept inline redirection function (will obsolete). [NOTE: THIS WAS REVERTED IN 1.79] + - 2020/06/15 (1.77) - removed CalcItemRectClosestPoint() entry point which was made obsolete and asserting in December 2017. + - 2020/04/23 (1.77) - removed unnecessary ID (first arg) of ImFontAtlas::AddCustomRectRegular(). + - 2020/01/22 (1.75) - ImDrawList::AddCircle()/AddCircleFilled() functions don't accept negative radius any more. + - 2019/12/17 (1.75) - [undid this change in 1.76] made Columns() limited to 64 columns by asserting above that limit. While the current code technically supports it, future code may not so we're putting the restriction ahead. + - 2019/12/13 (1.75) - [imgui_internal.h] changed ImRect() default constructor initializes all fields to 0.0f instead of (FLT_MAX,FLT_MAX,-FLT_MAX,-FLT_MAX). If you used ImRect::Add() to create bounding boxes by adding multiple points into it, you may need to fix your initial value. + - 2019/12/08 (1.75) - removed redirecting functions/enums that were marked obsolete in 1.53 (December 2017): + - ShowTestWindow() -> use ShowDemoWindow() + - IsRootWindowFocused() -> use IsWindowFocused(ImGuiFocusedFlags_RootWindow) + - IsRootWindowOrAnyChildFocused() -> use IsWindowFocused(ImGuiFocusedFlags_RootAndChildWindows) + - SetNextWindowContentWidth(w) -> use SetNextWindowContentSize(ImVec2(w, 0.0f) + - GetItemsLineHeightWithSpacing() -> use GetFrameHeightWithSpacing() + - ImGuiCol_ChildWindowBg -> use ImGuiCol_ChildBg + - ImGuiStyleVar_ChildWindowRounding -> use ImGuiStyleVar_ChildRounding + - ImGuiTreeNodeFlags_AllowOverlapMode -> use ImGuiTreeNodeFlags_AllowItemOverlap + - IMGUI_DISABLE_TEST_WINDOWS -> use IMGUI_DISABLE_DEMO_WINDOWS + - 2019/12/08 (1.75) - obsoleted calling ImDrawList::PrimReserve() with a negative count (which was vaguely documented and rarely if ever used). Instead, we added an explicit PrimUnreserve() API. + - 2019/12/06 (1.75) - removed implicit default parameter to IsMouseDragging(int button = 0) to be consistent with other mouse functions (none of the other functions have it). + - 2019/11/21 (1.74) - ImFontAtlas::AddCustomRectRegular() now requires an ID larger than 0x110000 (instead of 0x10000) to conform with supporting Unicode planes 1-16 in a future update. ID below 0x110000 will now assert. + - 2019/11/19 (1.74) - renamed IMGUI_DISABLE_FORMAT_STRING_FUNCTIONS to IMGUI_DISABLE_DEFAULT_FORMAT_FUNCTIONS for consistency. + - 2019/11/19 (1.74) - renamed IMGUI_DISABLE_MATH_FUNCTIONS to IMGUI_DISABLE_DEFAULT_MATH_FUNCTIONS for consistency. + - 2019/10/22 (1.74) - removed redirecting functions/enums that were marked obsolete in 1.52 (October 2017): + - Begin() [old 5 args version] -> use Begin() [3 args], use SetNextWindowSize() SetNextWindowBgAlpha() if needed + - IsRootWindowOrAnyChildHovered() -> use IsWindowHovered(ImGuiHoveredFlags_RootAndChildWindows) + - AlignFirstTextHeightToWidgets() -> use AlignTextToFramePadding() + - SetNextWindowPosCenter() -> use SetNextWindowPos() with a pivot of (0.5f, 0.5f) + - ImFont::Glyph -> use ImFontGlyph + - 2019/10/14 (1.74) - inputs: Fixed a miscalculation in the keyboard/mouse "typematic" repeat delay/rate calculation, used by keys and e.g. repeating mouse buttons as well as the GetKeyPressedAmount() function. + if you were using a non-default value for io.KeyRepeatRate (previous default was 0.250), you can add +io.KeyRepeatDelay to it to compensate for the fix. + The function was triggering on: 0.0 and (delay+rate*N) where (N>=1). Fixed formula responds to (N>=0). Effectively it made io.KeyRepeatRate behave like it was set to (io.KeyRepeatRate + io.KeyRepeatDelay). + If you never altered io.KeyRepeatRate nor used GetKeyPressedAmount() this won't affect you. + - 2019/07/15 (1.72) - removed TreeAdvanceToLabelPos() which is rarely used and only does SetCursorPosX(GetCursorPosX() + GetTreeNodeToLabelSpacing()). Kept redirection function (will obsolete). + - 2019/07/12 (1.72) - renamed ImFontAtlas::CustomRect to ImFontAtlasCustomRect. Kept redirection typedef (will obsolete). + - 2019/06/14 (1.72) - removed redirecting functions/enums names that were marked obsolete in 1.51 (June 2017): ImGuiCol_Column*, ImGuiSetCond_*, IsItemHoveredRect(), IsPosHoveringAnyWindow(), IsMouseHoveringAnyWindow(), IsMouseHoveringWindow(), IMGUI_ONCE_UPON_A_FRAME. Grep this log for details and new names, or see how they were implemented until 1.71. + - 2019/06/07 (1.71) - rendering of child window outer decorations (bg color, border, scrollbars) is now performed as part of the parent window. If you have + overlapping child windows in a same parent, and relied on their relative z-order to be mapped to their submission order, this will affect your rendering. + This optimization is disabled if the parent window has no visual output, because it appears to be the most common situation leading to the creation of overlapping child windows. + Please reach out if you are affected. + - 2019/05/13 (1.71) - renamed SetNextTreeNodeOpen() to SetNextItemOpen(). Kept inline redirection function (will obsolete). + - 2019/05/11 (1.71) - changed io.AddInputCharacter(unsigned short c) signature to io.AddInputCharacter(unsigned int c). + - 2019/04/29 (1.70) - improved ImDrawList thick strokes (>1.0f) preserving correct thickness up to 90 degrees angles (e.g. rectangles). If you have custom rendering using thick lines, they will appear thicker now. + - 2019/04/29 (1.70) - removed GetContentRegionAvailWidth(), use GetContentRegionAvail().x instead. Kept inline redirection function (will obsolete). + - 2019/03/04 (1.69) - renamed GetOverlayDrawList() to GetForegroundDrawList(). Kept redirection function (will obsolete). + - 2019/02/26 (1.69) - renamed ImGuiColorEditFlags_RGB/ImGuiColorEditFlags_HSV/ImGuiColorEditFlags_HEX to ImGuiColorEditFlags_DisplayRGB/ImGuiColorEditFlags_DisplayHSV/ImGuiColorEditFlags_DisplayHex. Kept redirection enums (will obsolete). + - 2019/02/14 (1.68) - made it illegal/assert when io.DisplayTime == 0.0f (with an exception for the first frame). If for some reason your time step calculation gives you a zero value, replace it with an arbitrarily small value! + - 2019/02/01 (1.68) - removed io.DisplayVisibleMin/DisplayVisibleMax (which were marked obsolete and removed from viewport/docking branch already). + - 2019/01/06 (1.67) - renamed io.InputCharacters[], marked internal as was always intended. Please don't access directly, and use AddInputCharacter() instead! + - 2019/01/06 (1.67) - renamed ImFontAtlas::GlyphRangesBuilder to ImFontGlyphRangesBuilder. Kept redirection typedef (will obsolete). + - 2018/12/20 (1.67) - made it illegal to call Begin("") with an empty string. This somehow half-worked before but had various undesirable side-effects. + - 2018/12/10 (1.67) - renamed io.ConfigResizeWindowsFromEdges to io.ConfigWindowsResizeFromEdges as we are doing a large pass on configuration flags. + - 2018/10/12 (1.66) - renamed misc/stl/imgui_stl.* to misc/cpp/imgui_stdlib.* in prevision for other C++ helper files. + - 2018/09/28 (1.66) - renamed SetScrollHere() to SetScrollHereY(). Kept redirection function (will obsolete). + - 2018/09/06 (1.65) - renamed stb_truetype.h to imstb_truetype.h, stb_textedit.h to imstb_textedit.h, and stb_rect_pack.h to imstb_rectpack.h. + If you were conveniently using the imgui copy of those STB headers in your project you will have to update your include paths. + - 2018/09/05 (1.65) - renamed io.OptCursorBlink/io.ConfigCursorBlink to io.ConfigInputTextCursorBlink. (#1427) + - 2018/08/31 (1.64) - added imgui_widgets.cpp file, extracted and moved widgets code out of imgui.cpp into imgui_widgets.cpp. Re-ordered some of the code remaining in imgui.cpp. + NONE OF THE FUNCTIONS HAVE CHANGED. THE CODE IS SEMANTICALLY 100% IDENTICAL, BUT _EVERY_ FUNCTION HAS BEEN MOVED. + Because of this, any local modifications to imgui.cpp will likely conflict when you update. Read docs/CHANGELOG.txt for suggestions. + - 2018/08/22 (1.63) - renamed IsItemDeactivatedAfterChange() to IsItemDeactivatedAfterEdit() for consistency with new IsItemEdited() API. Kept redirection function (will obsolete soonish as IsItemDeactivatedAfterChange() is very recent). + - 2018/08/21 (1.63) - renamed ImGuiTextEditCallback to ImGuiInputTextCallback, ImGuiTextEditCallbackData to ImGuiInputTextCallbackData for consistency. Kept redirection types (will obsolete). + - 2018/08/21 (1.63) - removed ImGuiInputTextCallbackData::ReadOnly since it is a duplication of (ImGuiInputTextCallbackData::Flags & ImGuiInputTextFlags_ReadOnly). + - 2018/08/01 (1.63) - removed per-window ImGuiWindowFlags_ResizeFromAnySide beta flag in favor of a global io.ConfigResizeWindowsFromEdges [update 1.67 renamed to ConfigWindowsResizeFromEdges] to enable the feature. + - 2018/08/01 (1.63) - renamed io.OptCursorBlink to io.ConfigCursorBlink [-> io.ConfigInputTextCursorBlink in 1.65], io.OptMacOSXBehaviors to ConfigMacOSXBehaviors for consistency. + - 2018/07/22 (1.63) - changed ImGui::GetTime() return value from float to double to avoid accumulating floating point imprecisions over time. + - 2018/07/08 (1.63) - style: renamed ImGuiCol_ModalWindowDarkening to ImGuiCol_ModalWindowDimBg for consistency with other features. Kept redirection enum (will obsolete). + - 2018/06/08 (1.62) - examples: the imgui_impl_XXX files have been split to separate platform (Win32, GLFW, SDL2, etc.) from renderer (DX11, OpenGL, Vulkan, etc.). + old backends will still work as is, however prefer using the separated backends as they will be updated to support multi-viewports. + when adopting new backends follow the main.cpp code of your preferred examples/ folder to know which functions to call. + in particular, note that old backends called ImGui::NewFrame() at the end of their ImGui_ImplXXXX_NewFrame() function. + - 2018/06/06 (1.62) - renamed GetGlyphRangesChinese() to GetGlyphRangesChineseFull() to distinguish other variants and discourage using the full set. + - 2018/06/06 (1.62) - TreeNodeEx()/TreeNodeBehavior(): the ImGuiTreeNodeFlags_CollapsingHeader helper now include the ImGuiTreeNodeFlags_NoTreePushOnOpen flag. See Changelog for details. + - 2018/05/03 (1.61) - DragInt(): the default compile-time format string has been changed from "%.0f" to "%d", as we are not using integers internally any more. + If you used DragInt() with custom format strings, make sure you change them to use %d or an integer-compatible format. + To honor backward-compatibility, the DragInt() code will currently parse and modify format strings to replace %*f with %d, giving time to users to upgrade their code. + If you have IMGUI_DISABLE_OBSOLETE_FUNCTIONS enabled, the code will instead assert! You may run a reg-exp search on your codebase for e.g. "DragInt.*%f" to help you find them. + - 2018/04/28 (1.61) - obsoleted InputFloat() functions taking an optional "int decimal_precision" in favor of an equivalent and more flexible "const char* format", + consistent with other functions. Kept redirection functions (will obsolete). + - 2018/04/09 (1.61) - IM_DELETE() helper function added in 1.60 doesn't clear the input _pointer_ reference, more consistent with expectation and allows passing r-value. + - 2018/03/20 (1.60) - renamed io.WantMoveMouse to io.WantSetMousePos for consistency and ease of understanding (was added in 1.52, _not_ used by core and only honored by some backend ahead of merging the Nav branch). + - 2018/03/12 (1.60) - removed ImGuiCol_CloseButton, ImGuiCol_CloseButtonActive, ImGuiCol_CloseButtonHovered as the closing cross uses regular button colors now. + - 2018/03/08 (1.60) - changed ImFont::DisplayOffset.y to default to 0 instead of +1. Fixed rounding of Ascent/Descent to match TrueType renderer. If you were adding or subtracting to ImFont::DisplayOffset check if your fonts are correctly aligned vertically. + - 2018/03/03 (1.60) - renamed ImGuiStyleVar_Count_ to ImGuiStyleVar_COUNT and ImGuiMouseCursor_Count_ to ImGuiMouseCursor_COUNT for consistency with other public enums. + - 2018/02/18 (1.60) - BeginDragDropSource(): temporarily removed the optional mouse_button=0 parameter because it is not really usable in many situations at the moment. + - 2018/02/16 (1.60) - obsoleted the io.RenderDrawListsFn callback, you can call your graphics engine render function after ImGui::Render(). Use ImGui::GetDrawData() to retrieve the ImDrawData* to display. + - 2018/02/07 (1.60) - reorganized context handling to be more explicit, + - YOU NOW NEED TO CALL ImGui::CreateContext() AT THE BEGINNING OF YOUR APP, AND CALL ImGui::DestroyContext() AT THE END. + - removed Shutdown() function, as DestroyContext() serve this purpose. + - you may pass a ImFontAtlas* pointer to CreateContext() to share a font atlas between contexts. Otherwise CreateContext() will create its own font atlas instance. + - removed allocator parameters from CreateContext(), they are now setup with SetAllocatorFunctions(), and shared by all contexts. + - removed the default global context and font atlas instance, which were confusing for users of DLL reloading and users of multiple contexts. + - 2018/01/31 (1.60) - moved sample TTF files from extra_fonts/ to misc/fonts/. If you loaded files directly from the imgui repo you may need to update your paths. + - 2018/01/11 (1.60) - obsoleted IsAnyWindowHovered() in favor of IsWindowHovered(ImGuiHoveredFlags_AnyWindow). Kept redirection function (will obsolete). + - 2018/01/11 (1.60) - obsoleted IsAnyWindowFocused() in favor of IsWindowFocused(ImGuiFocusedFlags_AnyWindow). Kept redirection function (will obsolete). + - 2018/01/03 (1.60) - renamed ImGuiSizeConstraintCallback to ImGuiSizeCallback, ImGuiSizeConstraintCallbackData to ImGuiSizeCallbackData. + - 2017/12/29 (1.60) - removed CalcItemRectClosestPoint() which was weird and not really used by anyone except demo code. If you need it it's easy to replicate on your side. + - 2017/12/24 (1.53) - renamed the emblematic ShowTestWindow() function to ShowDemoWindow(). Kept redirection function (will obsolete). + - 2017/12/21 (1.53) - ImDrawList: renamed style.AntiAliasedShapes to style.AntiAliasedFill for consistency and as a way to explicitly break code that manipulate those flag at runtime. You can now manipulate ImDrawList::Flags + - 2017/12/21 (1.53) - ImDrawList: removed 'bool anti_aliased = true' final parameter of ImDrawList::AddPolyline() and ImDrawList::AddConvexPolyFilled(). Prefer manipulating ImDrawList::Flags if you need to toggle them during the frame. + - 2017/12/14 (1.53) - using the ImGuiWindowFlags_NoScrollWithMouse flag on a child window forwards the mouse wheel event to the parent window, unless either ImGuiWindowFlags_NoInputs or ImGuiWindowFlags_NoScrollbar are also set. + - 2017/12/13 (1.53) - renamed GetItemsLineHeightWithSpacing() to GetFrameHeightWithSpacing(). Kept redirection function (will obsolete). + - 2017/12/13 (1.53) - obsoleted IsRootWindowFocused() in favor of using IsWindowFocused(ImGuiFocusedFlags_RootWindow). Kept redirection function (will obsolete). + - obsoleted IsRootWindowOrAnyChildFocused() in favor of using IsWindowFocused(ImGuiFocusedFlags_RootAndChildWindows). Kept redirection function (will obsolete). + - 2017/12/12 (1.53) - renamed ImGuiTreeNodeFlags_AllowOverlapMode to ImGuiTreeNodeFlags_AllowItemOverlap. Kept redirection enum (will obsolete). + - 2017/12/10 (1.53) - removed SetNextWindowContentWidth(), prefer using SetNextWindowContentSize(). Kept redirection function (will obsolete). + - 2017/11/27 (1.53) - renamed ImGuiTextBuffer::append() helper to appendf(), appendv() to appendfv(). If you copied the 'Log' demo in your code, it uses appendv() so that needs to be renamed. + - 2017/11/18 (1.53) - Style, Begin: removed ImGuiWindowFlags_ShowBorders window flag. Borders are now fully set up in the ImGuiStyle structure (see e.g. style.FrameBorderSize, style.WindowBorderSize). Use ImGui::ShowStyleEditor() to look them up. + Please note that the style system will keep evolving (hopefully stabilizing in Q1 2018), and so custom styles will probably subtly break over time. It is recommended you use the StyleColorsClassic(), StyleColorsDark(), StyleColorsLight() functions. + - 2017/11/18 (1.53) - Style: removed ImGuiCol_ComboBg in favor of combo boxes using ImGuiCol_PopupBg for consistency. + - 2017/11/18 (1.53) - Style: renamed ImGuiCol_ChildWindowBg to ImGuiCol_ChildBg. + - 2017/11/18 (1.53) - Style: renamed style.ChildWindowRounding to style.ChildRounding, ImGuiStyleVar_ChildWindowRounding to ImGuiStyleVar_ChildRounding. + - 2017/11/02 (1.53) - obsoleted IsRootWindowOrAnyChildHovered() in favor of using IsWindowHovered(ImGuiHoveredFlags_RootAndChildWindows); + - 2017/10/24 (1.52) - renamed IMGUI_DISABLE_WIN32_DEFAULT_CLIPBOARD_FUNCS/IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCS to IMGUI_DISABLE_WIN32_DEFAULT_CLIPBOARD_FUNCTIONS/IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCTIONS for consistency. + - 2017/10/20 (1.52) - changed IsWindowHovered() default parameters behavior to return false if an item is active in another window (e.g. click-dragging item from another window to this window). You can use the newly introduced IsWindowHovered() flags to requests this specific behavior if you need it. + - 2017/10/20 (1.52) - marked IsItemHoveredRect()/IsMouseHoveringWindow() as obsolete, in favor of using the newly introduced flags for IsItemHovered() and IsWindowHovered(). See https://github.com/ocornut/imgui/issues/1382 for details. + removed the IsItemRectHovered()/IsWindowRectHovered() names introduced in 1.51 since they were merely more consistent names for the two functions we are now obsoleting. + IsItemHoveredRect() --> IsItemHovered(ImGuiHoveredFlags_RectOnly) + IsMouseHoveringAnyWindow() --> IsWindowHovered(ImGuiHoveredFlags_AnyWindow) + IsMouseHoveringWindow() --> IsWindowHovered(ImGuiHoveredFlags_AllowWhenBlockedByPopup | ImGuiHoveredFlags_AllowWhenBlockedByActiveItem) [weird, old behavior] + - 2017/10/17 (1.52) - marked the old 5-parameters version of Begin() as obsolete (still available). Use SetNextWindowSize()+Begin() instead! + - 2017/10/11 (1.52) - renamed AlignFirstTextHeightToWidgets() to AlignTextToFramePadding(). Kept inline redirection function (will obsolete). + - 2017/09/26 (1.52) - renamed ImFont::Glyph to ImFontGlyph. Kept redirection typedef (will obsolete). + - 2017/09/25 (1.52) - removed SetNextWindowPosCenter() because SetNextWindowPos() now has the optional pivot information to do the same and more. Kept redirection function (will obsolete). + - 2017/08/25 (1.52) - io.MousePos needs to be set to ImVec2(-FLT_MAX,-FLT_MAX) when mouse is unavailable/missing. Previously ImVec2(-1,-1) was enough but we now accept negative mouse coordinates. In your backend if you need to support unavailable mouse, make sure to replace "io.MousePos = ImVec2(-1,-1)" with "io.MousePos = ImVec2(-FLT_MAX,-FLT_MAX)". + - 2017/08/22 (1.51) - renamed IsItemHoveredRect() to IsItemRectHovered(). Kept inline redirection function (will obsolete). -> (1.52) use IsItemHovered(ImGuiHoveredFlags_RectOnly)! + - renamed IsMouseHoveringAnyWindow() to IsAnyWindowHovered() for consistency. Kept inline redirection function (will obsolete). + - renamed IsMouseHoveringWindow() to IsWindowRectHovered() for consistency. Kept inline redirection function (will obsolete). + - 2017/08/20 (1.51) - renamed GetStyleColName() to GetStyleColorName() for consistency. + - 2017/08/20 (1.51) - added PushStyleColor(ImGuiCol idx, ImU32 col) overload, which _might_ cause an "ambiguous call" compilation error if you are using ImColor() with implicit cast. Cast to ImU32 or ImVec4 explicily to fix. + - 2017/08/15 (1.51) - marked the weird IMGUI_ONCE_UPON_A_FRAME helper macro as obsolete. prefer using the more explicit ImGuiOnceUponAFrame type. + - 2017/08/15 (1.51) - changed parameter order for BeginPopupContextWindow() from (const char*,int buttons,bool also_over_items) to (const char*,int buttons,bool also_over_items). Note that most calls relied on default parameters completely. + - 2017/08/13 (1.51) - renamed ImGuiCol_Column to ImGuiCol_Separator, ImGuiCol_ColumnHovered to ImGuiCol_SeparatorHovered, ImGuiCol_ColumnActive to ImGuiCol_SeparatorActive. Kept redirection enums (will obsolete). + - 2017/08/11 (1.51) - renamed ImGuiSetCond_Always to ImGuiCond_Always, ImGuiSetCond_Once to ImGuiCond_Once, ImGuiSetCond_FirstUseEver to ImGuiCond_FirstUseEver, ImGuiSetCond_Appearing to ImGuiCond_Appearing. Kept redirection enums (will obsolete). + - 2017/08/09 (1.51) - removed ValueColor() helpers, they are equivalent to calling Text(label) + SameLine() + ColorButton(). + - 2017/08/08 (1.51) - removed ColorEditMode() and ImGuiColorEditMode in favor of ImGuiColorEditFlags and parameters to the various Color*() functions. The SetColorEditOptions() allows to initialize default but the user can still change them with right-click context menu. + - changed prototype of 'ColorEdit4(const char* label, float col[4], bool show_alpha = true)' to 'ColorEdit4(const char* label, float col[4], ImGuiColorEditFlags flags = 0)', where passing flags = 0x01 is a safe no-op (hello dodgy backward compatibility!). - check and run the demo window, under "Color/Picker Widgets", to understand the various new options. + - changed prototype of rarely used 'ColorButton(ImVec4 col, bool small_height = false, bool outline_border = true)' to 'ColorButton(const char* desc_id, ImVec4 col, ImGuiColorEditFlags flags = 0, ImVec2 size = ImVec2(0, 0))' + - 2017/07/20 (1.51) - removed IsPosHoveringAnyWindow(ImVec2), which was partly broken and misleading. ASSERT + redirect user to io.WantCaptureMouse + - 2017/05/26 (1.50) - removed ImFontConfig::MergeGlyphCenterV in favor of a more multipurpose ImFontConfig::GlyphOffset. + - 2017/05/01 (1.50) - renamed ImDrawList::PathFill() (rarely used directly) to ImDrawList::PathFillConvex() for clarity. + - 2016/11/06 (1.50) - BeginChild(const char*) now applies the stack id to the provided label, consistently with other functions as it should always have been. It shouldn't affect you unless (extremely unlikely) you were appending multiple times to a same child from different locations of the stack id. If that's the case, generate an id with GetID() and use it instead of passing string to BeginChild(). + - 2016/10/15 (1.50) - avoid 'void* user_data' parameter to io.SetClipboardTextFn/io.GetClipboardTextFn pointers. We pass io.ClipboardUserData to it. + - 2016/09/25 (1.50) - style.WindowTitleAlign is now a ImVec2 (ImGuiAlign enum was removed). set to (0.5f,0.5f) for horizontal+vertical centering, (0.0f,0.0f) for upper-left, etc. + - 2016/07/30 (1.50) - SameLine(x) with x>0.0f is now relative to left of column/group if any, and not always to left of window. This was sort of always the intent and hopefully, breakage should be minimal. + - 2016/05/12 (1.49) - title bar (using ImGuiCol_TitleBg/ImGuiCol_TitleBgActive colors) isn't rendered over a window background (ImGuiCol_WindowBg color) anymore. + If your TitleBg/TitleBgActive alpha was 1.0f or you are using the default theme it will not affect you, otherwise if <1.0f you need to tweak your custom theme to readjust for the fact that we don't draw a WindowBg background behind the title bar. + This helper function will convert an old TitleBg/TitleBgActive color into a new one with the same visual output, given the OLD color and the OLD WindowBg color: + ImVec4 ConvertTitleBgCol(const ImVec4& win_bg_col, const ImVec4& title_bg_col) { float new_a = 1.0f - ((1.0f - win_bg_col.w) * (1.0f - title_bg_col.w)), k = title_bg_col.w / new_a; return ImVec4((win_bg_col.x * win_bg_col.w + title_bg_col.x) * k, (win_bg_col.y * win_bg_col.w + title_bg_col.y) * k, (win_bg_col.z * win_bg_col.w + title_bg_col.z) * k, new_a); } + If this is confusing, pick the RGB value from title bar from an old screenshot and apply this as TitleBg/TitleBgActive. Or you may just create TitleBgActive from a tweaked TitleBg color. + - 2016/05/07 (1.49) - removed confusing set of GetInternalState(), GetInternalStateSize(), SetInternalState() functions. Now using CreateContext(), DestroyContext(), GetCurrentContext(), SetCurrentContext(). + - 2016/05/02 (1.49) - renamed SetNextTreeNodeOpened() to SetNextTreeNodeOpen(), no redirection. + - 2016/05/01 (1.49) - obsoleted old signature of CollapsingHeader(const char* label, const char* str_id = NULL, bool display_frame = true, bool default_open = false) as extra parameters were badly designed and rarely used. You can replace the "default_open = true" flag in new API with CollapsingHeader(label, ImGuiTreeNodeFlags_DefaultOpen). + - 2016/04/26 (1.49) - changed ImDrawList::PushClipRect(ImVec4 rect) to ImDrawList::PushClipRect(Imvec2 min,ImVec2 max,bool intersect_with_current_clip_rect=false). Note that higher-level ImGui::PushClipRect() is preferable because it will clip at logic/widget level, whereas ImDrawList::PushClipRect() only affect your renderer. + - 2016/04/03 (1.48) - removed style.WindowFillAlphaDefault setting which was redundant. Bake default BG alpha inside style.Colors[ImGuiCol_WindowBg] and all other Bg color values. (ref GitHub issue #337). + - 2016/04/03 (1.48) - renamed ImGuiCol_TooltipBg to ImGuiCol_PopupBg, used by popups/menus and tooltips. popups/menus were previously using ImGuiCol_WindowBg. (ref github issue #337) + - 2016/03/21 (1.48) - renamed GetWindowFont() to GetFont(), GetWindowFontSize() to GetFontSize(). Kept inline redirection function (will obsolete). + - 2016/03/02 (1.48) - InputText() completion/history/always callbacks: if you modify the text buffer manually (without using DeleteChars()/InsertChars() helper) you need to maintain the BufTextLen field. added an assert. + - 2016/01/23 (1.48) - fixed not honoring exact width passed to PushItemWidth(), previously it would add extra FramePadding.x*2 over that width. if you had manual pixel-perfect alignment in place it might affect you. + - 2015/12/27 (1.48) - fixed ImDrawList::AddRect() which used to render a rectangle 1 px too large on each axis. + - 2015/12/04 (1.47) - renamed Color() helpers to ValueColor() - dangerously named, rarely used and probably to be made obsolete. + - 2015/08/29 (1.45) - with the addition of horizontal scrollbar we made various fixes to inconsistencies with dealing with cursor position. + GetCursorPos()/SetCursorPos() functions now include the scrolled amount. It shouldn't affect the majority of users, but take note that SetCursorPosX(100.0f) puts you at +100 from the starting x position which may include scrolling, not at +100 from the window left side. + GetContentRegionMax()/GetWindowContentRegionMin()/GetWindowContentRegionMax() functions allow include the scrolled amount. Typically those were used in cases where no scrolling would happen so it may not be a problem, but watch out! + - 2015/08/29 (1.45) - renamed style.ScrollbarWidth to style.ScrollbarSize + - 2015/08/05 (1.44) - split imgui.cpp into extra files: imgui_demo.cpp imgui_draw.cpp imgui_internal.h that you need to add to your project. + - 2015/07/18 (1.44) - fixed angles in ImDrawList::PathArcTo(), PathArcToFast() (introduced in 1.43) being off by an extra PI for no justifiable reason + - 2015/07/14 (1.43) - add new ImFontAtlas::AddFont() API. For the old AddFont***, moved the 'font_no' parameter of ImFontAtlas::AddFont** functions to the ImFontConfig structure. + you need to render your textured triangles with bilinear filtering to benefit from sub-pixel positioning of text. + - 2015/07/08 (1.43) - switched rendering data to use indexed rendering. this is saving a fair amount of CPU/GPU and enables us to get anti-aliasing for a marginal cost. + this necessary change will break your rendering function! the fix should be very easy. sorry for that :( + - if you are using a vanilla copy of one of the imgui_impl_XXX.cpp provided in the example, you just need to update your copy and you can ignore the rest. + - the signature of the io.RenderDrawListsFn handler has changed! + old: ImGui_XXXX_RenderDrawLists(ImDrawList** const cmd_lists, int cmd_lists_count) + new: ImGui_XXXX_RenderDrawLists(ImDrawData* draw_data). + parameters: 'cmd_lists' becomes 'draw_data->CmdLists', 'cmd_lists_count' becomes 'draw_data->CmdListsCount' + ImDrawList: 'commands' becomes 'CmdBuffer', 'vtx_buffer' becomes 'VtxBuffer', 'IdxBuffer' is new. + ImDrawCmd: 'vtx_count' becomes 'ElemCount', 'clip_rect' becomes 'ClipRect', 'user_callback' becomes 'UserCallback', 'texture_id' becomes 'TextureId'. + - each ImDrawList now contains both a vertex buffer and an index buffer. For each command, render ElemCount/3 triangles using indices from the index buffer. + - if you REALLY cannot render indexed primitives, you can call the draw_data->DeIndexAllBuffers() method to de-index the buffers. This is slow and a waste of CPU/GPU. Prefer using indexed rendering! + - refer to code in the examples/ folder or ask on the GitHub if you are unsure of how to upgrade. please upgrade! + - 2015/07/10 (1.43) - changed SameLine() parameters from int to float. + - 2015/07/02 (1.42) - renamed SetScrollPosHere() to SetScrollFromCursorPos(). Kept inline redirection function (will obsolete). + - 2015/07/02 (1.42) - renamed GetScrollPosY() to GetScrollY(). Necessary to reduce confusion along with other scrolling functions, because positions (e.g. cursor position) are not equivalent to scrolling amount. + - 2015/06/14 (1.41) - changed ImageButton() default bg_col parameter from (0,0,0,1) (black) to (0,0,0,0) (transparent) - makes a difference when texture have transparence + - 2015/06/14 (1.41) - changed Selectable() API from (label, selected, size) to (label, selected, flags, size). Size override should have been rarely used. Sorry! + - 2015/05/31 (1.40) - renamed GetWindowCollapsed() to IsWindowCollapsed() for consistency. Kept inline redirection function (will obsolete). + - 2015/05/31 (1.40) - renamed IsRectClipped() to IsRectVisible() for consistency. Note that return value is opposite! Kept inline redirection function (will obsolete). + - 2015/05/27 (1.40) - removed the third 'repeat_if_held' parameter from Button() - sorry! it was rarely used and inconsistent. Use PushButtonRepeat(true) / PopButtonRepeat() to enable repeat on desired buttons. + - 2015/05/11 (1.40) - changed BeginPopup() API, takes a string identifier instead of a bool. ImGui needs to manage the open/closed state of popups. Call OpenPopup() to actually set the "open" state of a popup. BeginPopup() returns true if the popup is opened. + - 2015/05/03 (1.40) - removed style.AutoFitPadding, using style.WindowPadding makes more sense (the default values were already the same). + - 2015/04/13 (1.38) - renamed IsClipped() to IsRectClipped(). Kept inline redirection function until 1.50. + - 2015/04/09 (1.38) - renamed ImDrawList::AddArc() to ImDrawList::AddArcFast() for compatibility with future API + - 2015/04/03 (1.38) - removed ImGuiCol_CheckHovered, ImGuiCol_CheckActive, replaced with the more general ImGuiCol_FrameBgHovered, ImGuiCol_FrameBgActive. + - 2014/04/03 (1.38) - removed support for passing -FLT_MAX..+FLT_MAX as the range for a SliderFloat(). Use DragFloat() or Inputfloat() instead. + - 2015/03/17 (1.36) - renamed GetItemBoxMin()/GetItemBoxMax()/IsMouseHoveringBox() to GetItemRectMin()/GetItemRectMax()/IsMouseHoveringRect(). Kept inline redirection function until 1.50. + - 2015/03/15 (1.36) - renamed style.TreeNodeSpacing to style.IndentSpacing, ImGuiStyleVar_TreeNodeSpacing to ImGuiStyleVar_IndentSpacing + - 2015/03/13 (1.36) - renamed GetWindowIsFocused() to IsWindowFocused(). Kept inline redirection function until 1.50. + - 2015/03/08 (1.35) - renamed style.ScrollBarWidth to style.ScrollbarWidth (casing) + - 2015/02/27 (1.34) - renamed OpenNextNode(bool) to SetNextTreeNodeOpened(bool, ImGuiSetCond). Kept inline redirection function until 1.50. + - 2015/02/27 (1.34) - renamed ImGuiSetCondition_*** to ImGuiSetCond_***, and _FirstUseThisSession becomes _Once. + - 2015/02/11 (1.32) - changed text input callback ImGuiTextEditCallback return type from void-->int. reserved for future use, return 0 for now. + - 2015/02/10 (1.32) - renamed GetItemWidth() to CalcItemWidth() to clarify its evolving behavior + - 2015/02/08 (1.31) - renamed GetTextLineSpacing() to GetTextLineHeightWithSpacing() + - 2015/02/01 (1.31) - removed IO.MemReallocFn (unused) + - 2015/01/19 (1.30) - renamed ImGuiStorage::GetIntPtr()/GetFloatPtr() to GetIntRef()/GetIntRef() because Ptr was conflicting with actual pointer storage functions. + - 2015/01/11 (1.30) - big font/image API change! now loads TTF file. allow for multiple fonts. no need for a PNG loader. + - 2015/01/11 (1.30) - removed GetDefaultFontData(). uses io.Fonts->GetTextureData*() API to retrieve uncompressed pixels. + - old: const void* png_data; unsigned int png_size; ImGui::GetDefaultFontData(NULL, NULL, &png_data, &png_size); [..Upload texture to GPU..]; + - new: unsigned char* pixels; int width, height; io.Fonts->GetTexDataAsRGBA32(&pixels, &width, &height); [..Upload texture to GPU..]; io.Fonts->SetTexID(YourTexIdentifier); + you now have more flexibility to load multiple TTF fonts and manage the texture buffer for internal needs. It is now recommended that you sample the font texture with bilinear interpolation. + - 2015/01/11 (1.30) - added texture identifier in ImDrawCmd passed to your render function (we can now render images). make sure to call io.Fonts->SetTexID() + - 2015/01/11 (1.30) - removed IO.PixelCenterOffset (unnecessary, can be handled in user projection matrix) + - 2015/01/11 (1.30) - removed ImGui::IsItemFocused() in favor of ImGui::IsItemActive() which handles all widgets + - 2014/12/10 (1.18) - removed SetNewWindowDefaultPos() in favor of new generic API SetNextWindowPos(pos, ImGuiSetCondition_FirstUseEver) + - 2014/11/28 (1.17) - moved IO.Font*** options to inside the IO.Font-> structure (FontYOffset, FontTexUvForWhite, FontBaseScale, FontFallbackGlyph) + - 2014/11/26 (1.17) - reworked syntax of IMGUI_ONCE_UPON_A_FRAME helper macro to increase compiler compatibility + - 2014/11/07 (1.15) - renamed IsHovered() to IsItemHovered() + - 2014/10/02 (1.14) - renamed IMGUI_INCLUDE_IMGUI_USER_CPP to IMGUI_INCLUDE_IMGUI_USER_INL and imgui_user.cpp to imgui_user.inl (more IDE friendly) + - 2014/09/25 (1.13) - removed 'text_end' parameter from IO.SetClipboardTextFn (the string is now always zero-terminated for simplicity) + - 2014/09/24 (1.12) - renamed SetFontScale() to SetWindowFontScale() + - 2014/09/24 (1.12) - moved IM_MALLOC/IM_REALLOC/IM_FREE preprocessor defines to IO.MemAllocFn/IO.MemReallocFn/IO.MemFreeFn + - 2014/08/30 (1.09) - removed IO.FontHeight (now computed automatically) + - 2014/08/30 (1.09) - moved IMGUI_FONT_TEX_UV_FOR_WHITE preprocessor define to IO.FontTexUvForWhite + - 2014/08/28 (1.09) - changed the behavior of IO.PixelCenterOffset following various rendering fixes + + + FREQUENTLY ASKED QUESTIONS (FAQ) + ================================ + + Read all answers online: + https://www.dearimgui.org/faq or https://github.com/ocornut/imgui/blob/master/docs/FAQ.md (same url) + Read all answers locally (with a text editor or ideally a Markdown viewer): + docs/FAQ.md + Some answers are copied down here to facilitate searching in code. + + Q&A: Basics + =========== + + Q: Where is the documentation? + A: This library is poorly documented at the moment and expects the user to be acquainted with C/C++. + - Run the examples/ and explore them. + - See demo code in imgui_demo.cpp and particularly the ImGui::ShowDemoWindow() function. + - The demo covers most features of Dear ImGui, so you can read the code and see its output. + - See documentation and comments at the top of imgui.cpp + effectively imgui.h. + - Dozens of standalone example applications using e.g. OpenGL/DirectX are provided in the + examples/ folder to explain how to integrate Dear ImGui with your own engine/application. + - The Wiki (https://github.com/ocornut/imgui/wiki) has many resources and links. + - The Glossary (https://github.com/ocornut/imgui/wiki/Glossary) page also may be useful. + - Your programming IDE is your friend, find the type or function declaration to find comments + associated with it. + + Q: What is this library called? + Q: Which version should I get? + >> This library is called "Dear ImGui", please don't call it "ImGui" :) + >> See https://www.dearimgui.org/faq for details. + + Q&A: Integration + ================ + + Q: How to get started? + A: Read 'PROGRAMMER GUIDE' above.

In this mode, it declares a +// single public symbol, STB_TexteditState, which encapsulates the current +// state of a text widget (except for the string, which you will store +// separately). +// +// To compile in this mode, you must define STB_TEXTEDIT_CHARTYPE to a +// primitive type that defines a single character (e.g. char, wchar_t, etc). +// +// To save space or increase undo-ability, you can optionally define the +// following things that are used by the undo system: +// +// STB_TEXTEDIT_POSITIONTYPE small int type encoding a valid cursor position +// STB_TEXTEDIT_UNDOSTATECOUNT the number of undo states to allow +// STB_TEXTEDIT_UNDOCHARCOUNT the number of characters to store in the undo buffer +// +// If you don't define these, they are set to permissive types and +// moderate sizes. The undo system does no memory allocations, so +// it grows STB_TexteditState by the worst-case storage which is (in bytes): +// +// [4 + 3 * sizeof(STB_TEXTEDIT_POSITIONTYPE)] * STB_TEXTEDIT_UNDOSTATE_COUNT +// + sizeof(STB_TEXTEDIT_CHARTYPE) * STB_TEXTEDIT_UNDOCHAR_COUNT +// +// +// Implementation mode: +// +// If you define STB_TEXTEDIT_IMPLEMENTATION before including this, it +// will compile the implementation of the text edit widget, depending +// on a large number of symbols which must be defined before the include. +// +// The implementation is defined only as static functions. You will then +// need to provide your own APIs in the same file which will access the +// static functions. +// +// The basic concept is that you provide a "string" object which +// behaves like an array of characters. stb_textedit uses indices to +// refer to positions in the string, implicitly representing positions +// in the displayed textedit. This is true for both plain text and +// rich text; even with rich text stb_truetype interacts with your +// code as if there was an array of all the displayed characters. +// +// Symbols that must be the same in header-file and implementation mode: +// +// STB_TEXTEDIT_CHARTYPE the character type +// STB_TEXTEDIT_POSITIONTYPE small type that is a valid cursor position +// STB_TEXTEDIT_UNDOSTATECOUNT the number of undo states to allow +// STB_TEXTEDIT_UNDOCHARCOUNT the number of characters to store in the undo buffer +// +// Symbols you must define for implementation mode: +// +// STB_TEXTEDIT_STRING the type of object representing a string being edited, +// typically this is a wrapper object with other data you need +// +// STB_TEXTEDIT_STRINGLEN(obj) the length of the string (ideally O(1)) +// STB_TEXTEDIT_LAYOUTROW(&r,obj,n) returns the results of laying out a line of characters +// starting from character #n (see discussion below) +// STB_TEXTEDIT_GETWIDTH(obj,n,i) returns the pixel delta from the xpos of the i'th character +// to the xpos of the i+1'th char for a line of characters +// starting at character #n (i.e. accounts for kerning +// with previous char) +// STB_TEXTEDIT_KEYTOTEXT(k) maps a keyboard input to an insertable character +// (return type is int, -1 means not valid to insert) +// STB_TEXTEDIT_GETCHAR(obj,i) returns the i'th character of obj, 0-based +// STB_TEXTEDIT_NEWLINE the character returned by _GETCHAR() we recognize +// as manually wordwrapping for end-of-line positioning +// +// STB_TEXTEDIT_DELETECHARS(obj,i,n) delete n characters starting at i +// STB_TEXTEDIT_INSERTCHARS(obj,i,c*,n) insert n characters at i (pointed to by STB_TEXTEDIT_CHARTYPE*) +// +// STB_TEXTEDIT_K_SHIFT a power of two that is or'd in to a keyboard input to represent the shift key +// +// STB_TEXTEDIT_K_LEFT keyboard input to move cursor left +// STB_TEXTEDIT_K_RIGHT keyboard input to move cursor right +// STB_TEXTEDIT_K_UP keyboard input to move cursor up +// STB_TEXTEDIT_K_DOWN keyboard input to move cursor down +// STB_TEXTEDIT_K_PGUP keyboard input to move cursor up a page +// STB_TEXTEDIT_K_PGDOWN keyboard input to move cursor down a page +// STB_TEXTEDIT_K_LINESTART keyboard input to move cursor to start of line // e.g. HOME +// STB_TEXTEDIT_K_LINEEND keyboard input to move cursor to end of line // e.g. END +// STB_TEXTEDIT_K_TEXTSTART keyboard input to move cursor to start of text // e.g. ctrl-HOME +// STB_TEXTEDIT_K_TEXTEND keyboard input to move cursor to end of text // e.g. ctrl-END +// STB_TEXTEDIT_K_DELETE keyboard input to delete selection or character under cursor +// STB_TEXTEDIT_K_BACKSPACE keyboard input to delete selection or character left of cursor +// STB_TEXTEDIT_K_UNDO keyboard input to perform undo +// STB_TEXTEDIT_K_REDO keyboard input to perform redo +// +// Optional: +// STB_TEXTEDIT_K_INSERT keyboard input to toggle insert mode +// STB_TEXTEDIT_IS_SPACE(ch) true if character is whitespace (e.g. 'isspace'), +// required for default WORDLEFT/WORDRIGHT handlers +// STB_TEXTEDIT_MOVEWORDLEFT(obj,i) custom handler for WORDLEFT, returns index to move cursor to +// STB_TEXTEDIT_MOVEWORDRIGHT(obj,i) custom handler for WORDRIGHT, returns index to move cursor to +// STB_TEXTEDIT_K_WORDLEFT keyboard input to move cursor left one word // e.g. ctrl-LEFT +// STB_TEXTEDIT_K_WORDRIGHT keyboard input to move cursor right one word // e.g. ctrl-RIGHT +// STB_TEXTEDIT_K_LINESTART2 secondary keyboard input to move cursor to start of line +// STB_TEXTEDIT_K_LINEEND2 secondary keyboard input to move cursor to end of line +// STB_TEXTEDIT_K_TEXTSTART2 secondary keyboard input to move cursor to start of text +// STB_TEXTEDIT_K_TEXTEND2 secondary keyboard input to move cursor to end of text +// +// Keyboard input must be encoded as a single integer value; e.g. a character code +// and some bitflags that represent shift states. to simplify the interface, SHIFT must +// be a bitflag, so we can test the shifted state of cursor movements to allow selection, +// i.e. (STB_TEXTEDIT_K_RIGHT|STB_TEXTEDIT_K_SHIFT) should be shifted right-arrow. +// +// You can encode other things, such as CONTROL or ALT, in additional bits, and +// then test for their presence in e.g. STB_TEXTEDIT_K_WORDLEFT. For example, +// my Windows implementations add an additional CONTROL bit, and an additional KEYDOWN +// bit. Then all of the STB_TEXTEDIT_K_ values bitwise-or in the KEYDOWN bit, +// and I pass both WM_KEYDOWN and WM_CHAR events to the "key" function in the +// API below. The control keys will only match WM_KEYDOWN events because of the +// keydown bit I add, and STB_TEXTEDIT_KEYTOTEXT only tests for the KEYDOWN +// bit so it only decodes WM_CHAR events. +// +// STB_TEXTEDIT_LAYOUTROW returns information about the shape of one displayed +// row of characters assuming they start on the i'th character--the width and +// the height and the number of characters consumed. This allows this library +// to traverse the entire layout incrementally.

STB_TEXTEDIT_KEYTYPE defaults to int, but you can #define it to +// anything other type you wante before including. +// +// +// When rendering, you can read the cursor position and selection state from +// the STB_TexteditState. +// +// +// Notes: +// +// This is designed to be usable in IMGUI, so it allows for the possibility of +// running in an IMGUI that has NOT cached the multi-line layout. For this +// reason, it provides an interface that is compatible with computing the +// layout incrementally--we try to make sure we make as few passes through +// as possible. (For example, to locate the mouse pointer in the text, we +// could define functions that return the X and Y positions of characters +// and binary search Y and then X, but if we're doing dynamic layout this +// will run the layout algorithm many times, so instead we manually search +// forward in one pass. Similar logic applies to e.g. up-arrow and +// down-arrow movement.) +// +// If it's run in a widget that *has* cached the layout, then this is less +// efficient, but it's not horrible on modern computers. But you wouldn't +// want to edit million-line files with it. + + +//////////////////////////////////////////////////////////////////////////// +//////////////////////////////////////////////////////////////////////////// +//// +//// Header-file mode +//// +//// + +#ifndef INCLUDE_STB_TEXTEDIT_H +#define INCLUDE_STB_TEXTEDIT_H + +//////////////////////////////////////////////////////////////////////// +// +// STB_TexteditState +// +// Definition of STB_TexteditState which you should store +// per-textfield;

Thus, anti-aliasing of intersecting shapes may look wrong. If +// this turns out to be a problem, you can re-enable the old rasterizer with +// #define STBTT_RASTERIZER_VERSION 1 +// which will incur about a 15% speed hit. +// +// ADDITIONAL DOCUMENTATION +// +// Immediately after this block comment are a series of sample programs. +// +// After the sample programs is the "header file" section. This section +// includes documentation for each API function. +// +// Some important concepts to understand to use this library: +// +// Codepoint +// Characters are defined by unicode codepoints, e.g. 65 is +// uppercase A, 231 is lowercase c with a cedilla, 0x7e30 is +// the hiragana for "ma". +// +// Glyph +// A visual character shape (every codepoint is rendered as +// some glyph) +// +// Glyph index +// A font-specific integer ID representing a glyph +// +// Baseline +// Glyph shapes are defined relative to a baseline, which is the +// bottom of uppercase characters. Characters extend both above +// and below the baseline. +// +// Current Point +// As you draw text to the screen, you keep track of a "current point" +// which is the origin of each character. The current point's vertical +// position is the baseline. Even "baked fonts" use this model. +// +// Vertical Font Metrics +// The vertical qualities of the font, used to vertically position +// and space the characters. See docs for stbtt_GetFontVMetrics. +// +// Font Size in Pixels or Points +// The preferred interface for specifying font sizes in stb_truetype +// is to specify how tall the font's vertical extent should be in pixels. +// If that sounds good enough, skip the next paragraph. +// +// Most font APIs instead use "points", which are a common typographic +// measurement for describing font size, defined as 72 points per inch. +// stb_truetype provides a point API for compatibility. However, true +// "per inch" conventions don't make much sense on computer displays +// since different monitors have different number of pixels per +// inch. For example, Windows traditionally uses a convention that +// there are 96 pixels per inch, thus making 'inch' measurements have +// nothing to do with inches, and thus effectively defining a point to +// be 1.333 pixels. Additionally, the TrueType font data provides +// an explicit scale factor to scale a given font's glyphs to points, +// but the author has observed that this scale factor is often wrong +// for non-commercial fonts, thus making fonts scaled in points +// according to the TrueType spec incoherently sized in practice. +// +// DETAILED USAGE: +// +// Scale: +// Select how high you want the font to be, in points or pixels. +// Call ScaleForPixelHeight or ScaleForMappingEmToPixels to compute +// a scale factor SF that will be used by all other functions. +// +// Baseline: +// You need to select a y-coordinate that is the baseline of where +// your text will appear. Call GetFontBoundingBox to get the baseline-relative +// bounding box for all characters. SF*-y0 will be the distance in pixels +// that the worst-case character could extend above the baseline, so if +// you want the top edge of characters to appear at the top of the +// screen where y=0, then you would set the baseline to SF*-y0. +// +// Current point: +// Set the current point where the first character will appear. The +// first character could extend left of the current point; this is font +// dependent. You can either choose a current point that is the leftmost +// point and hope, or add some padding, or check the bounding box or +// left-side-bearing of the first character to be displayed and set +// the current point based on that. +// +// Displaying a character: +// Compute the bounding box of the character. It will contain signed values +// relative to .
