VERSION 1.79 WIP (In Progress)
|
||||
-----------------------------------------------------------------------
|
||||
|
||||
Other Changes:
|
||||
|
||||
- InputText: Added selection helpers in ImGuiInputTextCallbackData().
|
||||
- InputText: Added ImGuiInputTextFlags_CallbackEdit to modify internally owned buffer after an edit.
|
||||
(note that InputText() already returns true on edit, the callback is useful mainly to manipulate the
|
||||
underlying buffer while focus is active).
|
||||
- DragFloat, DragScalar: Fixed ImGuiSliderFlags_ClampOnInput not being honored in the special case
|
||||
where v_min == v_max. (#3361)
|
||||
- BeginMenuBar: Fixed minor bug where CursorPosMax gets pushed to CursorPos prior to calling BeginMenuBar(),
|
||||
so e.g. calling the function at the end of a window would often add +ItemSpacing.y to scrolling range.
|
||||
- TreeNode, CollapsingHeader: Made clicking on arrow toggle toggle the open state on the Mouse Down event
|
||||
rather than the Mouse Down+Up sequence, even if the _OpenOnArrow flag isn't set. This is standard behavior
|
||||
and amends the change done in 1.76 which only affected cases were _OpenOnArrow flag was set.
|
||||
(This is also necessary to support full multi/range-select/drag and drop operations.)
|
||||
- Metrics: Various tweaks, listing windows front-to-back, greying inactive items when possible.
|
||||
- Demo: Add simple InputText() callbacks demo (aside from the more elaborate ones in 'Examples->Console').
