to not mess all topics there.
demo:
https://github.com/Alexey-T/ATFlatControls/tree/master/app/demo_tabs
Tabs 2nd and 3rd have custom hint.
When I move mouse over tabs (tab 2 and 3) I expect that hint refreshes ONLY on move to new tab.
gtk3: hint refreshed+flickers on EVERY mouse move.
Set breakpoint in TApplication.ActivateHint.
It's called in mouse move.
on gtk3, it goes to
HintControlChanged := not CheckHintControlChange or (FHintControl &LtPos;> Info.Control); if Info.ControlHasHint then begin if HintControlChanged then begin StopHintTimer; HideHint; FHintControl := Info.Control; FHintRect := FHintControl.BoundsRect; end;
so gtk3 has HintControlChanged=true! its a bug!
on mouse move inside one tab, control is the same.
