ocornut 46a050fff2 Nav: minor optimization NavUpdate(). 
To be honest this is mostly to ease debug stepping in the common case.

ocornut ac1f57ba0c Fixed BeginMenu() leading to window with is_resizable_width=true. Fix/amend 95bd1577d. (#9355) 
We should instead probably make BeginChild() not set on ImGuiWindowFlags_AlwaysAutoResize on either ResizeX or ResizeY, but that'll be done later.

ocornut bca5a69928 BeginMenu()/MenuItem(): fixed accidental triggering of child menu items when opening a menu inside a small host window forcing the child menu window to be repositioned under the mouse cursor. (#8233, #9394) 
nb: ImGuiSelectableFlags_NoHoldingActiveID is not used anymore. Would remove remove once we remove the unnecessary call to Selectable() from MenuItem().

ocornut a70b97ee48 Warning fixes. 2026-05-07 16:51:34 +02:00
ocornut 6df50a0667 (Breaking) DrawList: swapped the last two arguments of AddRect(), AddPolyline(), PathStroke(). thickness<>flags. 
Added inline redirection functions when IMGUI_DISABLE_OBSOLETE_FUNCTIONS is off.
Marked the old functions are =delete when IMGUI_DISABLE_OBSOLETE_FUNCTIONS is on, to allow for better type-checking.
The aim is to be able to use/add flags to more ImDrawList functions, and making existing functions consistents was deemed very desirable.

ocornut db23a78c60 Internals: store ImGuiItemStatusFlags_EditedInternal bypassing ImGuiItemFlags_NoMarkEdited.

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.

 2026-04-20 11:12:43 +02:00
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.
 2026-04-17 19:23:10 +02:00
ocornut cdb046ac3f Demo: Assets Browser: fixed not submitting anything after a SetCursorScreenPos() call when no items. Would not manifest because BeginMultiSelect() altered CursorMaxPos. (#5548)

ocornut 97939e6837 Multi-Select: Box-Select: fixes for using accross nested child windows. (#8364)

 2026-04-17 16:36:09 +02:00
ocornut c91b03060d Multi-Select: Box-Select: improve dirty unclip rectangle calculation + use in ImGuiMultiSelectFlags_BoxSelect1d mode when needed (e.g. wheel scrolling up). (#7994, #8250, #7821, #7850, #7970) 2026-04-17 14:38:12 +02:00

ocornut d4783bd553 Added missing Test Engine hooks for PlotXXX(), VSliderXXX(), TableHeader(). 2026-04-16 16:39:07 +02:00
ocornut ce855cada2 Tables, Multi-Select: Fixed an issue using Multi-Select within a Table causing column width measurement to be invalid when trailing column contents is not submitted in the last row. (#9341, #8250) 2026-04-16 15:21:56 +02:00
ocornut 39e7bf5a08 Separator(): enforce a minimum border size if style.SeparatorSize is 0.0f. (#9369) 2026-04-16 11:32:40 +02:00
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 3cd8683061 Fonts: assert when using MergeMode with an explicit size over a target font with an implicit size, as scale factor are likely erroneous. (#9361) 2026-04-13 16:45:18 +02:00
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.
