Hello, Items specific to the Qt widget set.

We have QApplication_focusChanged_Event, but we cannot attach it to the application object. Den, can you give a way to do that?

Best regards, Paul Ishenin.

look in mainwindow.pas :

Hook:=QApplication_hook_create(Handle);
QApplication_focusChanged_Event(Method):=FocusChanged;
QApplication_hook_hook_focusChanged(Hook,Method);

you could delete the hook at program exit.
but then again every memory is released at program exit anyhow.

why I have not seen that QApplication_hook_hook_focusChanged :)

Ok, I will delete it anyway in qt interface finalization code.
