// 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.

// (minor and older changes stripped away, please see git history for details)
// 2021-XX-XX: Platform: Added support for multiple windows via the ImGuiPlatformIO interface.
// 2022-01-10: Inputs: calling new io.AddKeyEvent(), io.AddKeyModEvent() + 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).

// (minor and older changes stripped away, please see git history for details)
// 2021-XX-XX: Platform: Added support for multiple windows via the ImGuiPlatformIO interface.
// 2022-01-10: Inputs: calling new io.AddKeyEvent(), io.AddKeyModEvent() + 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.

// [X] Platform: Mouse cursor shape and visibility. Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange'.
// [X] Platform: Keyboard arrays indexed using VK_* Virtual Key Codes, e.g. ImGui::IsKeyPressed(VK_SPACE).
// [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 VK_* values will also be supported unless IMGUI_DISABLE_OBSOLETE_KEYIO is set]

@ -104,6 +104,35 @@ Other changes:
Breaking Changes:
- Reworked IO keyboard input system. (#2625, #3724) [@thedmd, @ocornut]
- Added io.AddKeyEvent() function, obsoleting writing directly to io.KeyMap[], io.KeysDown[] arrays.
- Added io.AddKeyModEvent() function, obsoleting writing directly to io.KeyCtrl, io.KeyShift etc.
- Added io.SetKeyEventNativeData() function (optional) to pass native and old legacy indices.
- Added full range of key enums in ImGuiKey (e.g. ImGuiKey_F1).
- Added GetKeyName() helper function.
- Obsoleted GetKeyIndex(): it is now unnecessary and will now return the same value.
- All keyboard related functions taking 'int user_key_index' now take 'ImGuiKey key':
- IsKeyDown(), IsKeyPressed(), IsKeyReleased(), GetKeyPressedAmount().
- All backends were updated to use io.AddKeyEvent().
- Backward compatibility:
- Old backends populating those arrays will still work! (for a while)
- Calling e.g. IsKeyPressed(MY_NATIVE_KEY_XXX) will still work! (for a while)
- Those legacy arrays will only be disabled if '#define IMGUI_DISABLE_OBSOLETE_KEYIO' is set in your imconfig.
In a few versions, IMGUI_DISABLE_OBSOLETE_FUNCTIONS will automatically enable IMGUI_DISABLE_OBSOLETE_KEYIO,
so this will be moved into the regular obsolescence path.
- Transition guide:
- IsKeyPressed(MY_NATIVE_KEY_XXX) -> use IsKeyPressed(ImGuiKey_XXX)
- IsKeyPressed(GetKeyIndex(ImGuiKey_XXX)) -> use IsKeyPressed(ImGuiKey_XXX)
- Backend writing to io.KeyMap[],KeysDown[] -> backend should call io.AddKeyEvent(), if legacy indexing is desired, call io.SetKeyEventNativeData()
- Basically the trick we took advantage of is that we previously only supported native keycode from 0 to 511,
so ImGuiKey values can still express a legacy native keycode, and new named keys are all >= 512.
- This will enable a few things in the future:
- Access to portable keys allows for backed-agnostic keyboard input code. Until now it was difficult to
share code using keyboard accross project because of this gap. (#2625, #3724)
- Access to full key ranges will allow us to develop a proper keyboard shortcut system. (#456)
- io.AddKeyEvent() will later be turned into a trickling IO queue (for all inputs) to handle very low framerate better. (#2525, #2787, #3383)
- io.SetKeyEventNativeData() include native keycode/scancode which will later be exposed. (#3141, #2959)
- Renamed ImGuiKey_KeyPadEnter to ImGuiKey_KeypadEnter to align with new symbols. Kept redirection enum. (#2625)
- 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

- Backends: GLFW: Pass localized keys (matching keyboard layout). Fix e.g. CTRL+A, CTRL+Z, CTRL+Y shortcuts.
We are now converting GLFW untranslated keycodes back to translated keycodes in order to match the behavior of every
other backend, and facilitate the use of GLFW with lettered-shortcuts API. (#456, #2625)
