Comments, debug code (commented), todo list

WantCaptureMouse: Tweaked logic so WantCaptureMouse can stay false when e.g. hovering over void while an InputText() is active. (#621)

Exposed PushMultiItemsWidths() to imgui_internal.h

Merge pull request #1113 from Urmeli0815/ImGuiSelectableFlags_MenuItem ...

MenuItem: only activate on Release, not on Click (nb: and not on ClickRelease to allow opening menu and selecting something with a single click. Windows seems to behave the same, allowing to click and hold to e.g. Open then move cursor, release on Save and save gets activated)

Begin: Fixed auto-fit calculation code that predict the presence of ascrollbar so it works in the case size constraints are used. I actually don't need this fix now, but earlier experiment with BeginCombo() required this fix.

Begin: Moving some code into a CalcSizeAutoFit() function.

BeginCombo(): rework internals a little to make it easier to provide custom combo-like elements relying in BeginCombo(). ...

BeginPopupEx() doesn't enforce AlwaysAutoResize flag anymore.

SetNextWindowPos: added a ImVec2 pivot parameter for positioning a given a center, bottom-right position, etc. As a generalization of SetNextWindowPosCenter() which is now obsolete. This will be useful for combo-like popups as well. ...

Demo: Simple-overlay window uses the SetWindowPos pivot to select a corner to position itself at.

Begin(): Minor tidying up of flow

Window: Tweaked ApplySizeFullWithConstraint() -> CalcSizeFullWithConstraint() so it can be used without side-effect

Popups: Exposing a little more of popups internals in imgui_internals.h

ColorEdit: fixed weird ternary pattern that makes some compiler warning (fair)

BeginTooltipEx() internal tweaks

Merge branch 'master' into styles

PushStyleVar/PopStyleVar: internal tweaks

Style: Moving code in a function to make incoming diff easier to parse.

Merge branch 'master' into styles

More consistently uses "Dear ImGui"

Implicit "Debug" window uses a "Debug##Default" identifier to allow the user creating such window with custom flags

Internals: moved ButtonRepeat and AllowKeyboardFocus bools/stacks to a generic ItemFlags stack. Merged from Navigation branch.

BeginCombo() tweaks, merged from Navigation branch.

Fixed WantTextInput from being true when an activated Drag or Slider was previously turned into an InputText(). (#1317)

Minor comments + renaming internal fields

Improved ColorPicker hue wheel color interpolation

Begin(): fixed calling Begin() more than once per frame setting `window_just_activated_by_user` which in turn would set Appearing to true for that frame.

Begin(): renamed locals.

Begin(): Removed unnecessary code (at the time of 1.18 commit e9e0e36, CursorPos was used to compute SizeContentsFit and this was necessary)

Begin(): Tidying up some code, should be a no-op.

TODO, minor tweak

Combo: Internally split into BeginCombo(), EndCombo(), toward a more flexible combo api.
