ocornut a1e05521e9 Backends: GLFW: added a Win32-specific implementation of ImGui_ImplGlfw_GetContentScaleXXXX functions for legacy GLFW 3.2. (#9003) 
Since we ship GLFW 3.2 binaries for Windows this makes our examples a little better behaving by default.
Ideally we'd use ImGui_ImplWin32_GetDpiScaleForHwnd() and ImGui_ImplWin32_GetDpiScaleForMonitor() but they are too much code to copy.

ocornut ea1c04f7ab Multi-Select + Tables: fixed an issue which could lead to an extra vertical offset in the Header row. (#8250, #7994) 
Because BeginMultiSelect() does `ms->ScopeRectMin = window->DC.CursorMaxPos = window->DC.CursorPos` at a time where CursorPos is already past MaxPos.y because of ItemSpacing.y. Accumulate spacing.

ocornut 0e318a5182 Backends: SDL2: Made ImGui_ImplSDL2_GetContentScaleXXX helpers return a minimum of 1.0f, as some Linux setup seems to report <1.0f value and this breaks scaling border size. (#9369) 2026-04-16 11:32:07 +02:00
ocornut 19753a30d8 Multi-Select: Box-Select+Tables: fixed Column return value when UnClipRect is active. (#7994, #8250) 
Amend 6ce4b44 + bbd0af7. This probably should be redesigned to be more generic, e.g. move UnclipRect concept outside of Boxselect.

ocornut bbd0af7256 Multi-Select: Box-Select+Tables: fixed using BeginMultiSelect() before table layout is locked. (#8250) 2026-04-13 16:19:45 +02:00
ocornut f83a378d62 TabBar: changed edge's TabItem ClipRect to not pass an inverted PushClipRect(). 
While not currently a problem, it would be if ImRect::Overlaps() is changed to use <= instead of < (cc: #3976 which deal with Contains but sort of similar topic).
Changing ImDrawList::PushClipRect()'s intersect_with_current_clip_rect path to use ClipRectFull() would also fix this, but it may ambiguous there which behavior would be correct.
Amend 1ec464eb9.

ocornut 6ce4b44547 Mulit-Select: Box-Select: fixed an issue using in a table while relying on the TableNextColumn() return value to perform coarse clipping. (#7994) 
This is presumably not sufficient as MultiSelectAddSetRange() is also deficient there.
 2026-04-09 23:13:12 +02:00
ocornut f08b33fd0c Multi-Select: Box-Select: fixed an issue where items out of horizontal view would sometimes lead to incorrect merging of sequential selection requests. (#7994, #1861, #6518) 
SetNextItemSelectionUserData() could use g.NextItemData.SelectionUserData if we could guarantee if would be valid when nesting multi-select blocks.
But it doesn't make much of a difference as whole ImGuiMultiSelectTempData fits in 2 cache lines.
 2026-04-09 22:16:47 +02:00
ocornut b444694b3d Multi-Select: Box-Select: fixed an issue using ImGuiMultiSelectFlags_BoxSelect2d mode, where items out of view wouldn't be properly selected. (#7994, #1861, #6518) 
Because BoxSelectRectPrev and BoxSelectRectCurr were clamped to scope boundaries, dragging mouse outside of the scope would usually keep one axis unchanged.

ocornut 0867f6113a Tables: reorder allowed check sweep through columns, checks _NoOrder barrier, and reworked to be easy to use from context menu. (#9312) 
The sweep doesn't make a difference for reordering with headers as reordering is currently done 1 by 1. But menu ordering will change that.

ocornut 9fedea83f0 Tables: TableQueueSetColumnDisplayOrder() enforce handling ImGuiTableColumnFlags_NoReorder as advertised: can't reorder through them. (#9312) 
This would never using interactive reordering as reordering from headers was done on a 1 by 1 basis which was already covered in the test.
Hard to tell what's a sensible design for this tbh. Expecting _NoOrder columns to be sequential and leading/trailing anyhow.
