Summary0024735: TCustomControl, csNoFocus and TabStop
DescriptionTCustomControl is created with TabStop=True and with flag csNoFocus in ControlStyle. I know it is unusual.
When there is TabStop=True and with flag csNoFocus set, one of them should have precedence.
Behaviour should be the same for GTK and Qt.
Focus should be never lost.

I don't know what Delphi do it this special case.
Steps To ReproduceRun demo. Focus is on the Edit. The red rectangle cannot obtain focus on mouse click - correct.
But when you press "TAB", then
on Qt: focus is lost
on GTK: focus is on the red rectangle although it has csNoFocus in ControlStyle
Additional InformationLazarus 1.1 r42054M FPC 2.7.1 x86_64-linux-qt

IMO if csNoFocus is set than that control should not take focus in any case (mouse or kbd). Must look into Delphi docs to see what's exact meaning of csNoFocus.

csNoFocus is a LCL invention which is implemented only on carbon, cocoa and qt.
