Tables: Fix invalid data in TableGetSortSpecs() when SpecsDirty flag is unset. (#4233)
Amend4ce6bd8cf
, but with usage of ImPool<> bug existed even before4ce6bd8c
. Would only materialize if user called (ableGetSortSpecs and used data without checking SpecsDirty.

|
||||
- Tables: Added ImGuiTableColumnFlags_NoHeaderLabel to request TableHeadersRow() to not submit label for a column.
|
||||
Convenient for some small columns. Name will still appear in context menu. (#4206).
|
||||
- Tables: Fix columns order on TableSetupScrollFreeze() if previous data got frozen columns out of their section.
|
||||
- Tables: Fix invalid data in TableGetSortSpecs() when SpecsDirty flag is unset. (#4233)
|
||||
- Fixed printf-style format checks on non-MinGW flavors. (#4183, #3592)
|
||||
- Demo: Fixed requirement in 1.83 to link with imgui_demo.cpp if IMGUI_DISABLE_METRICS_WINDOW is not set. (#4171)
|
||||
Normally the right way to disable compiling the demo is to set IMGUI_DISABLE_DEMO_WINDOWS, but we want to avoid
