Does TListBox behave as expected?

Yes, OnSelectionChange of TListBox works.

OnSelectionChange can be triggered by code

lbWeekdays.Selected[1] := True;

But doesn't react to selection by mouse or keyboard.

Gtk2 is also fixed. Please test and close if ok, also make some tests so it can be included in 1.8 fixes.

GTK2: Works. Thank you!
QT: Works, except item 0 in the list doesn't fire the first time it is clicked. Seems to be selected already, but not marked blue? Therefore do not fire? Click another item and from then on all items trigger OnSelectionChange.
QT5: Can't test. Lazarus doesn't compile as qt5 for me.

Please test and close if ok. Added additional patch for first time click.
