@ -124,6 +124,21 @@ Breaking Changes:
Other Changes:
- Viewports Added ImGui::GetMainViewport() as a way to get the bounds and work area of the host display. (#3789, #1542)
- In 'master' branch or without multi-viewports feature enabled:
- GetMainViewport()->Pos is always == (0,0)
- GetMainViewport()->Size is always == io.DisplaySize
- In 'docking' branch and with the multi-viewports feature enabled:
- GetMainViewport() will return information from your host Platform Window.
- In the future, we will support a "no main viewport" mode and this may return bounds of your main monitor.
- For forward compatibility with multi-viewports/multi-monitors:
- Code using (0,0) as a way to signify "upper-left of the host window" should use GetMainViewport()->Pos.
- Code using io.DisplaySize as a way to signify "size of the host window" should use GetMainViewport()->Size.
- We are also exposing a work area in ImGuiViewport ('WorkPos', 'WorkSize' vs 'Pos', 'Size' for full area):
- For a Platform Window, the work area is generally the full area minus space used by menu-bars.
- For a Platform Monitor, the work area is generally the full area minus space used by task-bars.
- All of this has been the case in 'docking' branch for a long time. What we've done is merely merging
a small chunk of the multi-viewport logic into 'master' to standardize some concepts ahead of time.
- Tables: Fixed PopItemWidth() or multi-components items not restoring per-colum ItemWidth correctly. (#3760)
- Window: Fixed minor title bar text clipping issue when FramePadding is small/zero and there are no
close button in the window. (#3731)
@ -152,7 +167,9 @@ Other Changes:
Would lead to a buffer read overflow.
- ImDrawList: Clarified PathArcTo() need for a_min <= a_max with an assert.
- ImDrawList: Fixed PathArcToFast() handling of a_min > a_max.
- Demo: Added 'Examples->Fullscreen Window' demo. (#3789)
- Metrics: Backported "Viewports" debug visualizer from 'docking' branch.
- Demo: Added 'Examples->Fullscreen Window' demo using GetMainViewport() values. (#3789)
- Demo: 'Simple Overlay' demo now moves under main menu-bar (if any) using GetMainViewport()'s work area.
- Backends: Win32: Dynamically loading XInput DLL instead of linking with it, facilite compiling with
old WindowSDK versions or running on Windows 7. (#3646, #3645, #3248, #2716) [@Demonese]
- Backends: Vulkan: Add support for custom Vulkan function loader and VK_NO_PROTOTYPES. (#3759, #3227) [@Hossein-Noroozpour]
