- window: get size/pos helpers given names (see discussion in #249)
|
||||
- window: a collapsed window can be stuck behind the main menu bar?
|
||||
- window: detect extra End() call that pop the "Debug" window out and assert at call site instead of later.
|
||||
- window: consider renaming "GetWindowFont" which conflict with old Windows #define (#340)
|
||||
- window/tooltip: allow to set the width of a tooltip to allow TextWrapped() etc. while keeping the height automatic.
|
||||
- draw-list: maintaining bounding box per command would allow to merge draw command when clipping isn't relied on (typical non-scrolling window or non-overflowing column would merge with previous command).
|
||||
!- scrolling: allow immediately effective change of scroll if we haven't appended items yet
