I'll double check that as well, just to be sure.
Thanks to both for the very prompt replies. Much appreciated.
I checked again and it seems that Zeljko wrote Qt bindings so that they
take care of the csNoFocus flag. But no other WidgetSet does so. So
there probably is an incompatibility between LCL WidgetSets regarding this.
csNoFocus has no effect on plain win32 TWinControl and it's descendants
that do not handle csNoFocus explicitely (and are not bound to native
widgets - they are special, see below).
It is also so that some (maybe all) native win32 widgets (edit, button
etc.) always get focused automatically if they are clicked on with the
mouse and they are enabled - you cannot have a clickable TButton that
doesn't receive focus when clicked on but receives focus with TAB key.
With a custom non-native button it is perfectly possible.
