Changes (since v1.91.6)

Breaking Changes:

• TreeNode: renamed ImGuiTreeNodeFlags_SpanTextWidth to ImGuiTreeNodeFlags_SpanLabelWidth for consistency with other names. Kept redirection enum (will obsolete). (#6937)

Other changes:

• Fixed issues with IsItemDeactivated() and IsItemDeactivatedAfterEdit() not emitting a reliable signal when an item is deactivated externally: e.g. via an explicit clear of focus, clear of active id, opening of modal etc. (#5184, #5904, #6766, #8303, #8004)
  • It used to work when the interruption happened in the frame before the active item as submitted, but not after. It should work in both cases now.
  • While this is not specific to a certain widgets, typically it would mostly be noticeable on InputText() because it keeps ActiveId for a longer time while allowing other interaction to happen.
• Error Handling: Fixed bugs recovering from within a table that created a child window, and from nested child windows. (#1651)
• Error Handling: Turned common EndTable() and other TableXXX functions fail cases into a recoverable error. (#1651, #8314)
• Error Handling: Exposed basic error handling options in Demo->Tools->Debug Options. (#1651)
• InputText: Fixed a bug where character replacements performed from a callback were not applied when pasting from clipboard. (#8229)
• InputText: Fixed issue when activating a ReadOnly field when the underlying value is being modified. (#8242)
• InputText: Added sanity check to detect some cases of passing a non zero-terminated input buffer.
• InputText: Fixed not calling CallbackEdit on revert/clear with Escape key, although IsItemEdited() was behaving correctly. (#8273)
• Tables: Fixed TableAngledHeadersRow() creating an infinite horizontal scrolling region when the table is hosted in a viewport with negative coordinates (left of primary monitor, with multi-viewports enabled).
• Tables, MultiSelect: Fixed an issue where column width may be miss-measured when calling BeginMultiSelect() while inside a table. (#8250)
• TreeNode, Tables: Added ImGuiTreeNodeFlags_LabelSpanAllColumns to make the label (not only the highlight/frame) also spans all columns. This is useful for table rows where you know nothing else is submitted. (#8318, #3565) (Obviously best used with ImGuiTableFlags_NoBordersInBodyUntilResize).
• Drags: Added ImGuiSliderFlags_NoSpeedTweaks flag to disable keyboard modifiers altering the tweak speed. Useful if you want to alter tweak speed yourself based on your own logic. (#8223)
• Nav: Fixed an issue where Alt key would clear current active item on windows with the ImGuiWindowFlags_NoNavInputs flag. (#8231)
• Debug Tools: Debug Log: hovering 0xXXXXXXXX values in log is allowed even if a popup is blocking mouse access to the debug log window. (#5855)
• Debug Tools: Item Picker: Always available in Tools menu regardless of value of io.ConfigDebugIsDebuggerPresent. (#2673)
• Fonts: Fixed miscalculation of Ellipsis ("...") character width when automatically created from a single comma character, affecting some fonts/settings (not all).
• Demo: Added label edition to Property Editor demo + fix an ID issue. (#8266) [moritz-h]
• Misc: Fixed misc/cpp/imgui_stdlib.h/.cpp not supporting #define IMGUI_DISABLE. (#8294) [juur]
• Misc: Fixed MinGW builds not using UTF-8 friendly _wfopen(). (#8300)
• Backends: SDL_GPU for SDL3: Added backend for SDL_GPU! (#8163, #7998, #7988) [DeltaW0x].
• Backends: SDL3: Added ImGui_ImplSDL3_InitForSDLGPU() for consistency, even though it is currently not doing anything particular. (#8163, #7998, #7988)
• Backends: Allegro5: Avoid calling al_set_mouse_cursor() repeatedly since it appears to leak on on X11 (#8256). [Helodity]
• Backends: Metal: Fixed leaks when using metal-cpp. (#8276, #8166) [selimsandal]
• Backends: Metal: Fixed resource leak when using multiple contexts. (#7419) [anszom]
• Backends: Vulkan: Fixed setting VkSwapchainCreateInfoKHR::preTransform for platforms not supporting VK_SURFACE_TRANSFORM_IDENTITY_BIT_KHR. (#8222) [Zer0xFF]
• Backends: Vulkan: Added a few more ImGui_ImplVulkanH_XXX helper functions primarily for the purpose of making our examples simpler.
• Backends: Vulkan: Added IMGUI_IMPL_VULKAN_MINIMUM_IMAGE_SAMPLER_POOL_SIZE to clarify how many image sampler descriptors are expected to be available in the provided descriptor pool. Current backend needs 1 but it is expected that by end of Q1 2025 this number will grow (will stay a small number). (#6642)
• Backends: DX11: Expose vertex constant buffer in ImGui_ImplDX11_RenderState.
  Reset projection matrix in ImDrawCallback_ResetRenderState handlers. (#6969, #5834, #7468, #3590)
• Backends: DX10: Expose ImGui_ImplDX10_RenderState for completeness. (#6969, #5834, #7468, #3590)
• Examples: Added Win32+Vulkan example for completeness. (#8180) [jristic]
