@ -42,18 +42,25 @@ Breaking Changes:
Other Changes:
- Windows: fixed background order of overlapping childs submitted sequentially. (#4493)
- Windows: Fixed background order of overlapping childs submitted sequentially. (#4493)
- InputTextMultiline: Fixed label size not being included into window contents rect unless
the whole widget is clipped.
- InputText: Allow cancelling/validating input with gamepad nav events to facilitate undoing
an accidental press on NavInput (Triangle button on PS4/PS5) without a wired keyboard. (#2321)
- TextUnformatted: Accept null ranges including (NULL,NULL) without asserting, in order to conform
to common idioms (e.g. passing .data(), .data() + .size() from a null string). (#3615)
- Nav: Fixed toggling menu layer with Alt or exiting menu layer with Esc not moving mouse when
the NavEnableSetMousePos config flag is set.
- Menus: adjust closing logic to accomodate for varying font size and dpi.
- Drag and Drop: Fixed using BeginDragDropSource() inside a BeginChild() that returned false. (#4515)
- PlotHistogram: Fixed zero-line position when manually specifying min<0 and max>0. (#4349) [@filippocrocchini]
- IO: Added 'io.WantCaptureMouseUnlessPopupClose' alternative to `io.WantCaptureMouse'. (#4480)
This allows apps to receive the click on void when that click is used to close popup (by default,
clicking on a void when a popup is open will close the popup but not release io.WantCaptureMouse).
- Fonts: imgui_freetype: Fixed crash when FT_Render_Glyph() fails to render a glyph and returns NULL
(which apparently happens with Freetype 2.11). (#4394, #4145?).
- Fonts: Fixed ImFontAtlas::ClearInputData() marking atlas as not built. (#4455, #3487)
- Backends: OpenGL3: Fixed our new GL loader conflicting with user using GL3W. (#4445)
- Backends: OpenGL3: Fixed our custom GL loader conflicting with user using GL3W. (#4445) [@rokups]
- Backends: WebGPU: Fixed for latest specs. (#4472) [@Kangz]
- Backends: Metal: Fixed a crash when clipping rect larger than framebuffer is submitted via
a direct unclipped PushClipRect() call. (#4464)

@ -362,9 +362,10 @@ It's mostly a bunch of personal notes, probably incomplete. Feel free to query i
- nav: patterns to make it possible for arrows key to update selection (see JustMovedTo in range_select branch)
- nav: restore/find nearest NavId when current one disappear (e.g. pressed a button that disappear, or perhaps auto restoring when current button change name)
- nav: SetItemDefaultFocus() level of priority, so widget like Selectable when inside a popup could claim a low-priority default focus on the first selected iem
- nav: NavFlattened: init requests don't work properly on flattened siblings.
- nav: NavFlattened: pageup/pagedown/home/end don't work properly on flattened siblings.
- nav: NavFlattened: ESC on a flattened child should select something.
- nav: NavFlattened: broken: in typical usage scenario, the items of a fully clipped child are currently not considered to enter into a NavFlattened child.
- nav: NavFlattened: init request doesn't select items that are part of a NavFlattened child
- nav: NavFlattened: cannot access menu-bar of a flattened child window with Alt/menu key (not a very common use case..).
- nav: simulate right-click or context activation? (SHIFT+F10)
- nav/tabbing: refactor old tabbing system and turn into navigation, should pass through all widgets (in submission order?).
