description: "Provide an [MCVE](https://stackoverflow.com/help/mcve) to demonstrate your problem. An ideal submission includes a small piece of code that anyone can paste into one of the examples applications (examples/*/main.cpp) or the demo (imgui_demo.cpp) to understand and reproduce it. Narrowing your problem to its shortest and purest form is the easiest way to understand it, explain it and fix it. Please test your shortened code to ensure it exhibits the problem. Often while creating the MCVE you will solve the problem! Many questions that are missing a standalone verifiable example are missing the actual cause of their issue in the description, which ends up wasting everyone's time."

// dear imgui: Renderer + Platform Backend for Allegro 5
|
|
||||||
// (Info: Allegro 5 is a cross-platform general purpose library for handling windows, inputs, graphics, etc.)
|
|
||||||
|
|
||||||
// Implemented features:
|
|
||||||
// [X] Renderer: User texture binding. Use 'ALLEGRO_BITMAP*' as ImTextureID. Read the FAQ about ImTextureID!
|
|
||||||
// [X] Platform: Keyboard support. Since 1.87 we are using the io.AddKeyEvent() function. Pass ImGuiKey values to all key functions e.g. ImGui::IsKeyPressed(ImGuiKey_Space). [Legacy ALLEGRO_KEY_* values will also be supported unless IMGUI_DISABLE_OBSOLETE_KEYIO is set]
|
|
||||||
// [X] Platform: Clipboard support (from Allegro 5.1.12)
|
|
||||||
// [X] Platform: Mouse cursor shape and visibility. Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange'.
|
|
||||||
// Issues:
|
|
||||||
// [ ] Renderer: The renderer is suboptimal as we need to convert vertices manually.
|
|
||||||
// [ ] Platform: Missing gamepad support.
|
|
||||||
|
|
||||||
// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
|
|
||||||
// Prefer including the entire imgui/ repository into your project (either as a copy or as a submodule), and only build the backends you need.
|
|
||||||
// Learn about Dear ImGui:
|
|
||||||
// - FAQ https://dearimgui.com/faq
|
|
||||||
// - Getting Started https://dearimgui.com/getting-started
|
|
||||||
// - Documentation https://dearimgui.com/docs (same as your local docs/ folder).
|
|
||||||
// - Introduction, links and more at the top of imgui.cpp
|
|
||||||
|
|
||||||
// CHANGELOG
|
|
||||||
// (minor and older changes stripped away, please see git history for details)
|
|
||||||
// 2022-11-30: Renderer: Restoring using al_draw_indexed_prim() when Allegro version is >= 5.2.5.
|
|
||||||
// 2022-10-11: Using 'nullptr' instead of 'NULL' as per our switch to C++11.
|
|
||||||
// 2022-09-26: Inputs: Renamed ImGuiKey_ModXXX introduced in 1.87 to ImGuiMod_XXX (old names still supported).

// 2022-01-26: Inputs: replaced short-lived io.AddKeyModsEvent() (added two weeks ago) with io.AddKeyEvent() using ImGuiKey_ModXXX flags. Sorry for the confusion.
|
|
||||||
// 2022-01-17: Inputs: calling new io.AddMousePosEvent(), io.AddMouseButtonEvent(), io.AddMouseWheelEvent() API (1.87+).
|
|
||||||
// 2022-01-17: Inputs: always calling io.AddKeyModsEvent() next and before key event (not in NewFrame) to fix input queue with very low framerates.
|
|
||||||
// 2022-01-10: Inputs: calling new io.AddKeyEvent(), io.AddKeyModsEvent() + io.SetKeyEventNativeData() API (1.87+). Support for full ImGuiKey range.
|
|
||||||
// 2021-12-08: Renderer: Fixed mishandling of the the ImDrawCmd::IdxOffset field! This is an old bug but it never had an effect until some internal rendering changes in 1.86.
|
|
||||||
// 2021-08-17: Calling io.AddFocusEvent() on ALLEGRO_EVENT_DISPLAY_SWITCH_OUT/ALLEGRO_EVENT_DISPLAY_SWITCH_IN events.
|
|
||||||
// 2021-06-29: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).
|
|
||||||
// 2021-05-19: Renderer: Replaced direct access to ImDrawCmd::TextureId with a call to ImDrawCmd::GetTexID(). (will become a requirement)
|
|
||||||
// 2021-02-18: Change blending equation to preserve alpha in output buffer.
|
|
||||||
// 2020-08-10: Inputs: Fixed horizontal mouse wheel direction.
|
|
||||||
// 2019-12-05: Inputs: Added support for ImGuiMouseCursor_NotAllowed mouse cursor.
|
|
||||||
// 2019-07-21: Inputs: Added mapping for ImGuiKey_KeyPadEnter.
|
|
||||||
// 2019-05-11: Inputs: Don't filter character value from ALLEGRO_EVENT_KEY_CHAR before calling AddInputCharacter().
|
|
||||||
// 2019-04-30: Renderer: Added support for special ImDrawCallback_ResetRenderState callback to reset render state.
|
|
||||||
// 2018-11-30: Platform: Added touchscreen support.
|
|
||||||
// 2018-11-30: Misc: Setting up io.BackendPlatformName/io.BackendRendererName so they can be displayed in the About Window.
|
|
||||||
// 2018-06-13: Platform: Added clipboard support (from Allegro 5.1.12).
|
|
||||||
// 2018-06-13: Renderer: Use draw_data->DisplayPos and draw_data->DisplaySize to setup projection matrix and clipping rectangle.
|
|
||||||
// 2018-06-13: Renderer: Stopped using al_draw_indexed_prim() as it is buggy in Allegro's DX9 backend.
|
|
||||||
// 2018-06-13: Renderer: Backup/restore transform and clipping rectangle.
|
|
||||||
// 2018-06-11: Misc: Setup io.BackendFlags ImGuiBackendFlags_HasMouseCursors flag + honor ImGuiConfigFlags_NoMouseCursorChange flag.
|
|
||||||
// 2018-04-18: Misc: Renamed file from imgui_impl_a5.cpp to imgui_impl_allegro5.cpp.
|
|
||||||
// 2018-04-18: Misc: Added support for 32-bit vertex indices to avoid conversion at runtime. Added imconfig_allegro5.h to enforce 32-bit indices when included from imgui.h.
|
|
||||||
// 2018-02-16: Misc: Obsoleted the io.RenderDrawListsFn callback and exposed ImGui_ImplAllegro5_RenderDrawData() in the .h file so you can call it yourself.
|
|
||||||
// 2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves.
|
|
||||||
// 2018-02-06: Inputs: Added mapping for ImGuiKey_Space.

// 2022-09-26: Inputs: Renamed ImGuiKey_ModXXX introduced in 1.87 to ImGuiMod_XXX (old names still supported).
|
|
||||||
// 2022-01-26: Inputs: replaced short-lived io.AddKeyModsEvent() (added two weeks ago) with io.AddKeyEvent() using ImGuiKey_ModXXX flags. Sorry for the confusion.
|
|
||||||
// 2022-01-17: Inputs: calling new io.AddMousePosEvent(), io.AddMouseButtonEvent(), io.AddMouseWheelEvent() API (1.87+).
|
|
||||||
// 2022-01-10: Inputs: calling new io.AddKeyEvent(), io.AddKeyModsEvent() + io.SetKeyEventNativeData() API (1.87+). Support for full ImGuiKey range.

// Implemented features:

// [X] Platform: Keyboard support. Since 1.87 we are using the io.AddKeyEvent() function. Pass ImGuiKey values to all key functions e.g. ImGui::IsKeyPressed(ImGuiKey_Space). [Legacy AKEYCODE_* values will also be supported unless IMGUI_DISABLE_OBSOLETE_KEYIO is set]

// [X] Platform: Mouse support. Can discriminate Mouse/TouchScreen/Pen.
|
|

// Missing features:
|
|
||||||
// [ ] Platform: Clipboard support.
|
|
||||||
// [ ] Platform: Gamepad support. Enable with 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad'.
|
|

// [ ] Platform: Mouse cursor shape and visibility. Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange'. FIXME: Check if this is even possible with Android.
|
|
||||||
// Important:
|
|
||||||
// - Consider using SDL or GLFW backend on Android, which will be more full-featured than this.
|
|
||||||
// - FIXME: On-screen keyboard currently needs to be enabled by the application (see examples/ and issue #3446)

// CHANGELOG
|
|
||||||
// (minor and older changes stripped away, please see git history for details)
|
|
||||||
// 2022-10-11: Using 'nullptr' instead of 'NULL' as per our switch to C++11.
|
|
||||||
// 2021-06-29: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).
|
|
||||||
// 2021-05-19: DirectX10: Replaced direct access to ImDrawCmd::TextureId with a call to ImDrawCmd::GetTexID(). (will become a requirement)
|
|
||||||
// 2021-02-18: DirectX10: Change blending equation to preserve alpha in output buffer.
|
|
||||||
// 2019-07-21: DirectX10: Backup, clear and restore Geometry Shader is any is bound when calling ImGui_ImplDX10_RenderDrawData().
|
|
||||||
// 2019-05-29: DirectX10: Added support for large mesh (64K+ vertices), enable ImGuiBackendFlags_RendererHasVtxOffset flag.
|
|
||||||
// 2019-04-30: DirectX10: Added support for special ImDrawCallback_ResetRenderState callback to reset render state.
|
|
||||||
// 2018-12-03: Misc: Added #pragma comment statement to automatically link with d3dcompiler.lib when using D3DCompile().
|
|
||||||
// 2018-11-30: Misc: Setting up io.BackendRendererName so it can be displayed in the About Window.
|
|
||||||
// 2018-07-13: DirectX10: Fixed unreleased resources in Init and Shutdown functions.
|
|
||||||
// 2018-06-08: Misc: Extracted imgui_impl_dx10.cpp/.h away from the old combined DX10+Win32 example.
|
|
||||||
// 2018-06-08: DirectX10: Use draw_data->DisplayPos and draw_data->DisplaySize to setup projection matrix and clipping rectangle.
|
|
||||||
// 2018-04-09: Misc: Fixed erroneous call to io.Fonts->ClearInputData() + ClearTexData() that was left in DX10 example but removed in 1.47 (Nov 2015) on other backends.
|
|
||||||
// 2018-02-16: Misc: Obsoleted the io.RenderDrawListsFn callback and exposed ImGui_ImplDX10_RenderDrawData() in the .h file so you can call it yourself.
|
|
||||||
// 2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves.
|
|
||||||
// 2016-05-07: DirectX10: Disabling depth-write.

||||||
// 2022-10-11: Using 'nullptr' instead of 'NULL' as per our switch to C++11.
|
|
||||||
// 2021-06-29: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).
|
|
||||||
// 2021-05-19: DirectX11: Replaced direct access to ImDrawCmd::TextureId with a call to ImDrawCmd::GetTexID(). (will become a requirement)
|
|
||||||
// 2021-02-18: DirectX11: Change blending equation to preserve alpha in output buffer.
|
|
||||||
// 2019-08-01: DirectX11: Fixed code querying the Geometry Shader state (would generally error with Debug layer enabled).
|
|
||||||
// 2019-07-21: DirectX11: Backup, clear and restore Geometry Shader is any is bound when calling ImGui_ImplDX10_RenderDrawData. Clearing Hull/Domain/Compute shaders without backup/restore.
|
|
||||||
// 2019-05-29: DirectX11: Added support for large mesh (64K+ vertices), enable ImGuiBackendFlags_RendererHasVtxOffset flag.
|
|
||||||
// 2019-04-30: DirectX11: Added support for special ImDrawCallback_ResetRenderState callback to reset render state.
|
|
||||||
// 2018-12-03: Misc: Added #pragma comment statement to automatically link with d3dcompiler.lib when using D3DCompile().
|
|
||||||
// 2018-11-30: Misc: Setting up io.BackendRendererName so it can be displayed in the About Window.
|
|
||||||
// 2018-08-01: DirectX11: Querying for IDXGIFactory instead of IDXGIFactory1 to increase compatibility.
|
|
||||||
// 2018-07-13: DirectX11: Fixed unreleased resources in Init and Shutdown functions.
|
|
||||||
// 2018-06-08: Misc: Extracted imgui_impl_dx11.cpp/.h away from the old combined DX11+Win32 example.
|
|
||||||
// 2018-06-08: DirectX11: Use draw_data->DisplayPos and draw_data->DisplaySize to setup projection matrix and clipping rectangle.
|
|
||||||
// 2018-02-16: Misc: Obsoleted the io.RenderDrawListsFn callback and exposed ImGui_ImplDX11_RenderDrawData() in the .h file so you can call it yourself.

// - [Solution 1] IDE/msbuild: in "Properties/C++/Preprocessor Definitions" add 'ImTextureID=ImU64' (this is what we do in the 'example_win32_direct12/example_win32_direct12.vcxproj' project file)
|
|

// - [Solution 2] IDE/msbuild: in "Properties/C++/Preprocessor Definitions" add 'IMGUI_USER_CONFIG="my_imgui_config.h"' and inside 'my_imgui_config.h' add '#define ImTextureID ImU64' and as many other options as you like.
|
|

// - [Solution 3] IDE/msbuild: edit imconfig.h and add '#define ImTextureID ImU64' (prefer solution 2 to create your own config file!)

// 2021-06-29: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).
|
|
||||||
// 2021-05-19: DirectX12: Replaced direct access to ImDrawCmd::TextureId with a call to ImDrawCmd::GetTexID(). (will become a requirement)
|
|
||||||
// 2021-02-18: DirectX12: Change blending equation to preserve alpha in output buffer.
|
|
||||||
// 2021-01-11: DirectX12: Improve Windows 7 compatibility (for D3D12On7) by loading d3d12.dll dynamically.
|
|
||||||
// 2020-09-16: DirectX12: Avoid rendering calls with zero-sized scissor rectangle since it generates a validation layer warning.
|
|
||||||
// 2020-09-08: DirectX12: Clarified support for building on 32-bit systems by redefining ImTextureID.
|
|
||||||
// 2019-10-18: DirectX12: *BREAKING CHANGE* Added extra ID3D12DescriptorHeap parameter to ImGui_ImplDX12_Init() function.
|
|
||||||
// 2019-05-29: DirectX12: Added support for large mesh (64K+ vertices), enable ImGuiBackendFlags_RendererHasVtxOffset flag.

// 2022-10-11: Using 'nullptr' instead of 'NULL' as per our switch to C++11.
|
|
||||||
// 2021-06-29: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).
|
|
||||||
// 2021-06-25: DirectX9: Explicitly disable texture state stages after >= 1.
|
|
||||||
// 2021-05-19: DirectX9: Replaced direct access to ImDrawCmd::TextureId with a call to ImDrawCmd::GetTexID(). (will become a requirement)
|
|
||||||
// 2021-04-23: DirectX9: Explicitly setting up more graphics states to increase compatibility with unusual non-default states.
|
|
||||||
// 2021-03-18: DirectX9: Calling IDirect3DStateBlock9::Capture() after CreateStateBlock() as a workaround for state restoring issues (see #3857).
|
|
||||||
// 2021-03-03: DirectX9: Added support for IMGUI_USE_BGRA_PACKED_COLOR in user's imconfig file.
|
|
||||||
// 2021-02-18: DirectX9: Change blending equation to preserve alpha in output buffer.
|
|
||||||
// 2019-05-29: DirectX9: Added support for large mesh (64K+ vertices), enable ImGuiBackendFlags_RendererHasVtxOffset flag.
|
|
||||||
// 2019-04-30: DirectX9: Added support for special ImDrawCallback_ResetRenderState callback to reset render state.
|
|
||||||
// 2019-03-29: Misc: Fixed erroneous assert in ImGui_ImplDX9_InvalidateDeviceObjects().
|
|
||||||
// 2019-01-16: Misc: Disabled fog before drawing UI's. Fixes issue #2288.
|
|
||||||
// 2018-11-30: Misc: Setting up io.BackendRendererName so it can be displayed in the About Window.
|
|
||||||
// 2018-06-08: Misc: Extracted imgui_impl_dx9.cpp/.h away from the old combined DX9+Win32 example.
|
|
||||||
// 2018-06-08: DirectX9: Use draw_data->DisplayPos and draw_data->DisplaySize to setup projection matrix and clipping rectangle.
|
|
||||||
// 2018-05-07: Render: Saving/restoring Transform because they don't seem to be included in the StateBlock. Setting shading mode to Gouraud.
|
|
||||||
// 2018-02-16: Misc: Obsoleted the io.RenderDrawListsFn callback and exposed ImGui_ImplDX9_RenderDrawData() in the .h file so you can call it yourself.
|
|
||||||
// 2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves.

|

// (minor and older changes stripped away, please see git history for details)
|
|
||||||
// 2023-12-19: Emscripten: Added ImGui_ImplGlfw_InstallEmscriptenCanvasResizeCallback() to register canvas selector and auto-resize GLFW window.
|
|
||||||
// 2023-10-05: Inputs: Added support for extra ImGuiKey values: F13 to F24 function keys.
|
|
||||||
// 2023-07-18: Inputs: Revert ignoring mouse data on GLFW_CURSOR_DISABLED as it can be used differently. User may set ImGuiConfigFLags_NoMouse if desired. (#5625, #6609)
|
|
||||||
// 2023-06-12: Accept glfwGetTime() not returning a monotonically increasing value. This seems to happens on some Windows setup when peripherals disconnect, and is likely to also happen on browser + Emscripten. (#6491)
|
|
||||||
// 2023-04-04: Inputs: Added support for io.AddMouseSourceEvent() to discriminate ImGuiMouseSource_Mouse/ImGuiMouseSource_TouchScreen/ImGuiMouseSource_Pen on Windows ONLY, using a custom WndProc hook. (#2702)
|
|
||||||
// 2023-03-16: Inputs: Fixed key modifiers handling on secondary viewports (docking branch). Broken on 2023/01/04. (#6248, #6034)
|
|
||||||
// 2023-03-14: Emscripten: Avoid using glfwGetError() and glfwGetGamepadState() which are not correctly implemented in Emscripten emulation. (#6240)
|
|
||||||
// 2023-02-03: Emscripten: Registering custom low-level mouse wheel handler to get more accurate scrolling impulses on Emscripten. (#4019, #6096)
|
|
||||||
// 2023-01-04: Inputs: Fixed mods state on Linux when using Alt-GR text input (e.g. German keyboard layout), could lead to broken text input. Revert a 2022/01/17 change were we resumed using mods provided by GLFW, turns out they were faulty.
|
|
||||||
// 2022-11-22: Perform a dummy glfwGetError() read to cancel missing names with glfwGetKeyName(). (#5908)
|
|
||||||
// 2022-10-18: Perform a dummy glfwGetError() read to cancel missing mouse cursors errors. Using GLFW_VERSION_COMBINED directly. (#5785)
|
|
||||||
// 2022-10-11: Using 'nullptr' instead of 'NULL' as per our switch to C++11.
|
|
||||||
// 2022-09-26: Inputs: Renamed ImGuiKey_ModXXX introduced in 1.87 to ImGuiMod_XXX (old names still supported).
|
|
||||||
// 2022-09-01: Inputs: Honor GLFW_CURSOR_DISABLED by not setting mouse position *EDIT* Reverted 2023-07-18.
|
|
||||||
// 2022-04-30: Inputs: Fixed ImGui_ImplGlfw_TranslateUntranslatedKey() for lower case letters on OSX.
|
|
||||||
// 2022-03-23: Inputs: Fixed a regression in 1.87 which resulted in keyboard modifiers events being reported incorrectly on Linux/X11.
|
|
||||||
// 2022-02-07: Added ImGui_ImplGlfw_InstallCallbacks()/ImGui_ImplGlfw_RestoreCallbacks() helpers to facilitate user installing callbacks after initializing backend.
|
|
||||||
// 2022-01-26: Inputs: replaced short-lived io.AddKeyModsEvent() (added two weeks ago) with io.AddKeyEvent() using ImGuiKey_ModXXX flags. Sorry for the confusion.
|
|
||||||
// 2021-01-20: Inputs: calling new io.AddKeyAnalogEvent() for gamepad support, instead of writing directly to io.NavInputs[].
|
|
||||||
// 2022-01-17: Inputs: calling new io.AddMousePosEvent(), io.AddMouseButtonEvent(), io.AddMouseWheelEvent() API (1.87+).
|
|
||||||
// 2022-01-17: Inputs: always update key mods next and before key event (not in NewFrame) to fix input queue with very low framerates.
|
|
||||||
// 2022-01-12: *BREAKING CHANGE*: Now using glfwSetCursorPosCallback(). If you called ImGui_ImplGlfw_InitXXX() with install_callbacks = false, you MUST install glfwSetCursorPosCallback() and forward it to the backend via ImGui_ImplGlfw_CursorPosCallback().
|
|
||||||
// 2022-01-10: Inputs: calling new io.AddKeyEvent(), io.AddKeyModsEvent() + io.SetKeyEventNativeData() API (1.87+). Support for full ImGuiKey range.
|
|
||||||
// 2022-01-05: Inputs: Converting GLFW untranslated keycodes back to translated keycodes (in the ImGui_ImplGlfw_KeyCallback() function) in order to match the behavior of every other backend, and facilitate the use of GLFW with lettered-shortcuts API.
|
|
||||||
// 2021-08-17: *BREAKING CHANGE*: Now using glfwSetWindowFocusCallback() to calling io.AddFocusEvent(). If you called ImGui_ImplGlfw_InitXXX() with install_callbacks = false, you MUST install glfwSetWindowFocusCallback() and forward it to the backend via ImGui_ImplGlfw_WindowFocusCallback().
|
|
||||||
// 2021-07-29: *BREAKING CHANGE*: Now using glfwSetCursorEnterCallback(). MousePos is correctly reported when the host platform window is hovered but not focused. If you called ImGui_ImplGlfw_InitXXX() with install_callbacks = false, you MUST install glfwSetWindowFocusCallback() callback and forward it to the backend via ImGui_ImplGlfw_CursorEnterCallback().
|
|
||||||
// 2021-06-29: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).
|
|
||||||
// 2020-01-17: Inputs: Disable error callback while assigning mouse cursors because some X11 setup don't have them and it generates errors.
|
|

// 2019-12-05: Inputs: Added support for new mouse cursors added in GLFW 3.4+ (resizing cursors, not allowed cursor).
|

|

|

// !!! GLUT/FreeGLUT IS OBSOLETE PREHISTORIC SOFTWARE. Using GLUT is not recommended unless you really miss the 90's. !!!
|
|
||||||
// !!! If someone or something is teaching you GLUT today, you are being abused. Please show some resistance. !!!
|
|
||||||
// !!! Nowadays, prefer using GLFW or SDL instead!
|
|
||||||
|
|
||||||
// Implemented features:
|
|
||||||
// [X] Platform: Partial keyboard support. Since 1.87 we are using the io.AddKeyEvent() function. Pass ImGuiKey values to all key functions e.g. ImGui::IsKeyPressed(ImGuiKey_Space). [Legacy GLUT values will also be supported unless IMGUI_DISABLE_OBSOLETE_KEYIO is set]
|
|
||||||
// Issues:
|
|
||||||
// [ ] Platform: GLUT is unable to distinguish e.g. Backspace from CTRL+H or TAB from CTRL+I
|
|
||||||
// [ ] Platform: Missing horizontal mouse wheel support.
|
|
||||||
// [ ] Platform: Missing mouse cursor shape/visibility support.
|
|
||||||
// [ ] Platform: Missing clipboard support (not supported by Glut).
|
|
||||||
// [ ] Platform: Missing gamepad support.
|
|
||||||
|
|
||||||
// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.

// dear imgui: Renderer Backend for Metal
|
|
||||||
// This needs to be used along with a Platform Backend (e.g. OSX)
|
|
||||||
|
|
||||||
// Implemented features:
|
|
||||||
// [X] Renderer: User texture binding. Use 'MTLTexture' as ImTextureID. Read the FAQ about ImTextureID!
|
|
||||||
// [X] Renderer: Large meshes support (64k+ vertices) with 16-bit indices.
|
|
||||||
|
|
||||||
// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
|
|
||||||
// Prefer including the entire imgui/ repository into your project (either as a copy or as a submodule), and only build the backends you need.
|
|
||||||
// Learn about Dear ImGui:
|
|

|
|
||||||
// CHANGELOG
|
|
||||||
// (minor and older changes stripped away, please see git history for details)
|
|
||||||
// 2022-08-23: Metal: Update deprecated property 'sampleCount'->'rasterSampleCount'.
|
|
||||||
// 2022-07-05: Metal: Add dispatch synchronization.
|
|
||||||
// 2022-06-30: Metal: Use __bridge for ARC based systems.
|
|
||||||
// 2022-06-01: Metal: Fixed null dereference on exit inside command buffer completion handler.
|
|
||||||
// 2022-04-27: Misc: Store backend data in a per-context struct, allowing to use this backend with multiple contexts.
|
|
||||||
// 2022-01-03: Metal: Ignore ImDrawCmd where ElemCount == 0 (very rare but can technically be manufactured by user code).
|
|
||||||
// 2021-12-30: Metal: Added Metal C++ support. Enable with '#define IMGUI_IMPL_METAL_CPP' in your imconfig.h file.
|
|
||||||
// 2021-08-24: Metal: Fixed a crash when clipping rect larger than framebuffer is submitted. (#4464)
|
|
||||||
// 2021-05-19: Metal: Replaced direct access to ImDrawCmd::TextureId with a call to ImDrawCmd::GetTexID(). (will become a requirement)
|
|
||||||
// 2021-02-18: Metal: Change blending equation to preserve alpha in output buffer.
|
|
||||||
// 2021-01-25: Metal: Fixed texture storage mode when building on Mac Catalyst.
|
|
||||||
// 2019-05-29: Metal: Added support for large mesh (64K+ vertices), enable ImGuiBackendFlags_RendererHasVtxOffset flag.
|
|
||||||
// 2019-04-30: Metal: Added support for special ImDrawCallback_ResetRenderState callback to reset render state.
|
|
||||||
// 2019-02-11: Metal: Projecting clipping rectangles correctly using draw_data->FramebufferScale to allow multi-viewports for retina display.
|
|
||||||
// 2018-11-30: Misc: Setting up io.BackendRendererName so it can be displayed in the About Window.
|
|
||||||
// 2018-07-05: Metal: Added new Metal backend implementation.

// - Desktop GL: 2.x 3.x 4.x
|
|
||||||
// - Embedded GL: ES 2.0 (WebGL 1.0), ES 3.0 (WebGL 2.0)
|
|
||||||
// This needs to be used along with a Platform Backend (e.g. GLFW, SDL, Win32, custom..)
|
|
||||||
|
|
||||||
// Implemented features:
|
|
||||||
// [X] Renderer: User texture binding. Use 'GLuint' OpenGL texture identifier as void*/ImTextureID. Read the FAQ about ImTextureID!
|
|
||||||
// [x] Renderer: Large meshes support (64k+ vertices) with 16-bit indices (Desktop OpenGL only).
|

// About WebGL/ES:
|
|
||||||
// - You need to '#define IMGUI_IMPL_OPENGL_ES2' or '#define IMGUI_IMPL_OPENGL_ES3' to use WebGL or OpenGL ES.
|
|
||||||
// - This is done automatically on iOS, Android and Emscripten targets.
|
|
||||||
// - For other targets, the define needs to be visible from the imgui_impl_opengl3.cpp compilation unit. If unsure, define globally or in imconfig.h.
|
|
||||||
|
|
||||||
// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
|
|
||||||
// Prefer including the entire imgui/ repository into your project (either as a copy or as a submodule), and only build the backends you need.

// About imgui_impl_opengl3_loader.h:
|
|
||||||
//
|
|
||||||
// We embed our own OpenGL loader to not require user to provide their own or to have to use ours,
|
|
||||||
// which proved to be endless problems for users.
|
|
||||||
// Our loader is custom-generated, based on gl3w but automatically filtered to only include
|
|
||||||
// enums/functions that we use in our imgui_impl_opengl3.cpp source file in order to be small.
|
|
||||||
//
|
|
||||||
// YOU SHOULD NOT NEED TO INCLUDE/USE THIS DIRECTLY. THIS IS USED BY imgui_impl_opengl3.cpp ONLY.
|
|
||||||
// THE REST OF YOUR APP SHOULD USE A DIFFERENT GL LOADER: ANY GL LOADER OF YOUR CHOICE.
|
|
||||||
//
|
|
||||||
// IF YOU GET BUILD ERRORS IN THIS FILE (commonly macro redefinitions or function redefinitions):
|
|
||||||
// IT LIKELY MEANS THAT YOU ARE BUILDING 'imgui_impl_opengl3.cpp' OR INCUDING 'imgui_impl_opengl3_loader.h'
|
|
||||||
// IN THE SAME COMPILATION UNIT AS ONE OF YOUR FILE WHICH IS USING A THIRD-PARTY OPENGL LOADER.
|
|
||||||
// (e.g. COULD HAPPEN IF YOU ARE DOING A UNITY/JUMBO BUILD, OR INCLUDING .CPP FILES FROM OTHERS)
|
|
||||||
// YOU SHOULD NOT BUILD BOTH IN THE SAME COMPILATION UNIT.
|
|
||||||
// BUT IF YOU REALLY WANT TO, you can '#define IMGUI_IMPL_OPENGL_LOADER_CUSTOM' and imgui_impl_opengl3.cpp
|
|
||||||
// WILL NOT BE USING OUR LOADER, AND INSTEAD EXPECT ANOTHER/YOUR LOADER TO BE AVAILABLE IN THE COMPILATION UNIT.

|
||||||
// 2023-04-09: Inputs: Added support for io.AddMouseSourceEvent() to discriminate ImGuiMouseSource_Mouse/ImGuiMouseSource_Pen.
|
|
||||||
// 2023-02-01: Fixed scroll wheel scaling for devices emitting events with hasPreciseScrollingDeltas==false (e.g. non-Apple mices).
|
|
||||||
// 2022-11-02: Fixed mouse coordinates before clicking the host window.
|
|
||||||
// 2022-10-06: Fixed mouse inputs on flipped views.

/**

KeyEventResponder implements the NSTextInputClient protocol as is required by the macOS text input manager.
|
|
||||||
|
|
||||||
The macOS text input manager is invoked by calling the interpretKeyEvents method from the keyDown method.
|
|
||||||
Keyboard events are then evaluated by the macOS input manager and valid text input is passed back via the
|
|
||||||
insertText:replacementRange method.
|
|
||||||
|
|
||||||
This is the same approach employed by other cross-platform libraries such as SDL2:
|
|
||||||

|
|
||||||
and GLFW:

||||||

// 2023-10-05: Inputs: Added support for extra ImGuiKey values: F13 to F24 function keys, app back/forward keys.
|
|
||||||
// 2023-04-06: Inputs: Avoid calling SDL_StartTextInput()/SDL_StopTextInput() as they don't only pertain to IME. It's unclear exactly what their relation is to IME. (#6306)
|
|
||||||
// 2023-04-04: Inputs: Added support for io.AddMouseSourceEvent() to discriminate ImGuiMouseSource_Mouse/ImGuiMouseSource_TouchScreen. (#2702)
|
|
||||||
// 2023-02-23: Accept SDL_GetPerformanceCounter() not returning a monotonically increasing value. (#6189, #6114, #3644)
|
|
||||||
// 2023-02-07: Implement IME handler (io.SetPlatformImeDataFn will call SDL_SetTextInputRect()/SDL_StartTextInput()).
|
|
||||||
// 2023-02-07: *BREAKING CHANGE* Renamed this backend file from imgui_impl_sdl.cpp/.h to imgui_impl_sdl2.cpp/.h in prevision for the future release of SDL3.
|
|
||||||
// 2023-02-02: Avoid calling SDL_SetCursor() when cursor has not changed, as the function is surprisingly costly on Mac with latest SDL (may be fixed in next SDL version).
|
|
||||||
// 2023-02-02: Added support for SDL 2.0.18+ preciseX/preciseY mouse wheel data for smooth scrolling + Scaling X value on Emscripten (bug?). (#4019, #6096)
|
|
||||||
// 2023-02-02: Removed SDL_MOUSEWHEEL value clamping, as values seem correct in latest Emscripten. (#4019)
|
|
||||||
// 2023-02-01: Flipping SDL_MOUSEWHEEL 'wheel.x' value to match other backends and offer consistent horizontal scrolling direction. (#4019, #6096, #1463)
|
|
||||||
// 2022-10-11: Using 'nullptr' instead of 'NULL' as per our switch to C++11.
|
|
||||||
// 2022-09-26: Inputs: Disable SDL 2.0.22 new "auto capture" (SDL_HINT_MOUSE_AUTO_CAPTURE) which prevents drag and drop across windows for multi-viewport support + don't capture when drag and dropping. (#5710)
|
|
||||||
// 2022-09-26: Inputs: Renamed ImGuiKey_ModXXX introduced in 1.87 to ImGuiMod_XXX (old names still supported).
|
|
||||||
// 2022-03-22: Inputs: Fix mouse position issues when dragging outside of boundaries. SDL_CaptureMouse() erroneously still gives out LEAVE events when hovering OS decorations.
|
|
||||||
// 2022-03-22: Inputs: Added support for extra mouse buttons (SDL_BUTTON_X1/SDL_BUTTON_X2).
|
|
||||||
// 2022-02-04: Added SDL_Renderer* parameter to ImGui_ImplSDL2_InitForSDLRenderer(), so we can use SDL_GetRendererOutputSize() instead of SDL_GL_GetDrawableSize() when bound to a SDL_Renderer.
|
|
||||||
// 2022-01-26: Inputs: replaced short-lived io.AddKeyModsEvent() (added two weeks ago) with io.AddKeyEvent() using ImGuiKey_ModXXX flags. Sorry for the confusion.
|
|
||||||
// 2021-01-20: Inputs: calling new io.AddKeyAnalogEvent() for gamepad support, instead of writing directly to io.NavInputs[].
|
|
||||||
// 2022-01-17: Inputs: calling new io.AddMousePosEvent(), io.AddMouseButtonEvent(), io.AddMouseWheelEvent() API (1.87+).
|
|
||||||
// 2022-01-17: Inputs: always update key mods next and before key event (not in NewFrame) to fix input queue with very low framerates.
|
|
||||||
// 2022-01-12: Update mouse inputs using SDL_MOUSEMOTION/SDL_WINDOWEVENT_LEAVE + fallback to provide it when focused but not hovered/captured. More standard and will allow us to pass it to future input queue API.
|
|
||||||
// 2022-01-12: Maintain our own copy of MouseButtonsDown mask instead of using ImGui::IsAnyMouseDown() which will be obsoleted.
|
|
||||||
// 2022-01-10: Inputs: calling new io.AddKeyEvent(), io.AddKeyModsEvent() + io.SetKeyEventNativeData() API (1.87+). Support for full ImGuiKey range.
|
|
||||||
// 2021-08-17: Calling io.AddFocusEvent() on SDL_WINDOWEVENT_FOCUS_GAINED/SDL_WINDOWEVENT_FOCUS_LOST.
|
|
||||||
// 2021-07-29: Inputs: MousePos is correctly reported when the host platform window is hovered but not focused (using SDL_GetMouseFocus() + SDL_HINT_MOUSE_FOCUS_CLICKTHROUGH, requires SDL 2.0.5+)
|
|
||||||
// 2021-06-29: *BREAKING CHANGE* Removed 'SDL_Window* window' parameter to ImGui_ImplSDL2_NewFrame() which was unnecessary.
|
|
||||||
// 2021-06-29: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).
|
|
||||||
// 2021-03-22: Rework global mouse pos availability check listing supported platforms explicitly, effectively fixing mouse access on Raspberry Pi. (#2837, #3950)
|
|
||||||
// 2020-05-25: Misc: Report a zero display-size when window is minimized, to be consistent with other backends.
|
|
||||||
// 2020-02-20: Inputs: Fixed mapping for ImGuiKey_KeyPadEnter (using SDL_SCANCODE_KP_ENTER instead of SDL_SCANCODE_RETURN2).
|
|
||||||
// 2019-12-17: Inputs: On Wayland, use SDL_GetMouseState (because there is no global mouse state).
|
|
||||||
// 2019-12-05: Inputs: Added support for ImGuiMouseCursor_NotAllowed mouse cursor.
|
|
||||||
// 2019-07-21: Inputs: Added mapping for ImGuiKey_KeyPadEnter.
|
|
||||||
// 2019-04-23: Inputs: Added support for SDL_GameController (if ImGuiConfigFlags_NavEnableGamepad is set by user application).
|
|
||||||
// 2019-03-12: Misc: Preserve DisplayFramebufferScale when main window is minimized.
|
|
||||||
// 2018-12-21: Inputs: Workaround for Android/iOS which don't seem to handle focus related calls.
|
|
||||||
// 2018-11-30: Misc: Setting up io.BackendPlatformName so it can be displayed in the About Window.
|
|
||||||
// 2018-11-14: Changed the signature of ImGui_ImplSDL2_ProcessEvent() to take a 'const SDL_Event*'.
|
|
||||||
// 2018-08-01: Inputs: Workaround for Emscripten which doesn't seem to handle focus related calls.
|
|
||||||
// 2018-06-29: Inputs: Added support for the ImGuiMouseCursor_Hand cursor.
|
|
||||||
// 2018-06-08: Misc: Extracted imgui_impl_sdl.cpp/.h away from the old combined SDL2+OpenGL/Vulkan examples.
|
|
||||||
// 2018-06-08: Misc: ImGui_ImplSDL2_InitForOpenGL() now takes a SDL_GLContext parameter.
|
|
||||||
// 2018-05-09: Misc: Fixed clipboard paste memory leak (we didn't call SDL_FreeMemory on the data returned by SDL_GetClipboardText).
|
|
||||||
// 2018-03-20: Misc: Setup io.BackendFlags ImGuiBackendFlags_HasMouseCursors flag + honor ImGuiConfigFlags_NoMouseCursorChange flag.
|
|
||||||
// 2018-02-16: Inputs: Added support for mouse cursors, honoring ImGui::GetMouseCursor() value.
|
|
||||||
// 2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves.
|
|
||||||
// 2018-02-06: Inputs: Added mapping for ImGuiKey_Space.
|
|
||||||
// 2018-02-05: Misc: Using SDL_GetPerformanceCounter() instead of SDL_GetTicks() to be able to handle very high framerate (1000+ FPS).
|
|
||||||
// 2018-02-05: Inputs: Keyboard mapping is using scancodes everywhere instead of a confusing mixture of keycodes and scancodes.
|
|
||||||
// 2018-01-20: Inputs: Added Horizontal Mouse Wheel support.
|
|
||||||
// 2018-01-19: Inputs: When available (SDL 2.0.4+) using SDL_CaptureMouse() to retrieve coordinates outside of client area when dragging. Otherwise (SDL 2.0.3 and before) testing for SDL_WINDOW_INPUT_FOCUS instead of SDL_WINDOW_MOUSE_FOCUS.
|
|
||||||
// 2018-01-18: Inputs: Added mapping for ImGuiKey_Insert.
|
|
||||||
// 2017-08-25: Inputs: MousePos set to -FLT_MAX,-FLT_MAX when mouse is unavailable/missing (instead of -1,-1).
|
|
||||||
// 2016-10-15: Misc: Added a void* user_data parameter to Clipboard function handlers.

// 2023-11-13: Updated for recent SDL3 API changes.
|
|
||||||
// 2023-10-05: Inputs: Added support for extra ImGuiKey values: F13 to F24 function keys, app back/forward keys.
|
|
||||||
// 2023-05-04: Fixed build on Emscripten/iOS/Android. (#6391)
|
|
||||||
// 2023-04-06: Inputs: Avoid calling SDL_StartTextInput()/SDL_StopTextInput() as they don't only pertain to IME. It's unclear exactly what their relation is to IME. (#6306)
|
|
||||||
// 2023-04-04: Inputs: Added support for io.AddMouseSourceEvent() to discriminate ImGuiMouseSource_Mouse/ImGuiMouseSource_TouchScreen. (#2702)
|
|
||||||
// 2023-02-23: Accept SDL_GetPerformanceCounter() not returning a monotonically increasing value. (#6189, #6114, #3644)
|
|
||||||
// 2023-02-07: Forked "imgui_impl_sdl2" into "imgui_impl_sdl3". Removed version checks for old feature. Refer to imgui_impl_sdl2.cpp for older changelog.

// This needs to be used along with a Renderer (e.g. DirectX11, OpenGL3, Vulkan..)
|
|
||||||
// (Info: SDL3 is a cross-platform general purpose library for handling windows, inputs, graphics context creation, etc.)
|
|
||||||
// (IMPORTANT: SDL 3.0.0 is NOT YET RELEASED. IT IS POSSIBLE THAT ITS SPECS/API WILL CHANGE BEFORE RELEASE)
|
|
||||||
|
|
||||||
// Implemented features:
|
|
||||||
// [X] Platform: Clipboard support.
|
|
||||||
// [X] Platform: Mouse support. Can discriminate Mouse/TouchScreen.
|
|
||||||
// [X] Platform: Keyboard support. Since 1.87 we are using the io.AddKeyEvent() function. Pass ImGuiKey values to all key functions e.g. ImGui::IsKeyPressed(ImGuiKey_Space). [Legacy SDL_SCANCODE_* values will also be supported unless IMGUI_DISABLE_OBSOLETE_KEYIO is set]
|
|
||||||
// [X] Platform: Gamepad support. Enabled with 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad'.
|
|
||||||
// [X] Platform: Mouse cursor shape and visibility. Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange'.
|
|
||||||
// Missing features:
|
|
||||||
// [x] Platform: Basic IME support. Position somehow broken in SDL3 + app needs to call 'SDL_SetHint(SDL_HINT_IME_SHOW_UI, "1");' before SDL_CreateWindow()!.

// dear imgui: Renderer Backend for Vulkan
|
|
||||||
// This needs to be used along with a Platform Backend (e.g. GLFW, SDL, Win32, custom..)
|
|
||||||
|
|
||||||
// Implemented features:
|
|
||||||
// [!] Renderer: User texture binding. Use 'VkDescriptorSet' as ImTextureID. Read the FAQ about ImTextureID! See https://github.com/ocornut/imgui/pull/914 for discussions.
|
|
||||||
// [X] Renderer: Large meshes support (64k+ vertices) with 16-bit indices.
|
|
||||||
|
|
||||||
// Important: on 32-bit systems, user texture binding is only supported if your imconfig file has '#define ImTextureID ImU64'.
|
|
||||||
// See imgui_impl_vulkan.cpp file for details.
|
|
||||||
|
|
||||||
// The aim of imgui_impl_vulkan.h/.cpp is to be usable in your engine without any modification.
|
|
||||||
// IF YOU FEEL YOU NEED TO MAKE ANY CHANGE TO THIS CODE, please share them and your feedback at https://github.com/ocornut/imgui/
|
|
||||||
|
|
||||||
// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
|
|
||||||
// Prefer including the entire imgui/ repository into your project (either as a copy or as a submodule), and only build the backends you need.

// Important note to the reader who wish to integrate imgui_impl_vulkan.cpp/.h in their own engine/app.
|
|
||||||
// - Common ImGui_ImplVulkan_XXX functions and structures are used to interface with imgui_impl_vulkan.cpp/.h.
|
|
||||||
// You will use those if you want to use this rendering backend in your engine/app.
|
|
||||||
// - Helper ImGui_ImplVulkanH_XXX functions and structures are only used by this example (main.cpp) and by
|
|
||||||
// the backend itself (imgui_impl_vulkan.cpp), but should PROBABLY NOT be used by your own engine/app code.
