Problem at Minimizing QDockWidget

Hey,

I have implemented my own dock widget and title widget. titile widget has minimize, maximize, dock/undock and close buttons. when I minimized the dock widget, it appears like that :

when i double clicked the minimized title widget, it dockes itself to a dock window. what i want is to replace the dock widget to its old geometry. i tried to overwrite WindowStateChange and mouseDoubleClickEvent, but that did not work (qt does not return those events in minimized state). is it possible to show tool buttons in minimized state or overwrite doube clicking?

Here is my own dock title :

Here is my minimizing function:

Code:

---

void KtDockTitle::on_pbMin_clicked()
{
	if(!parentWidget()->isWindow())
		return;
 
	if(parentWidget()->isMinimized())
	{
		parentWidget()->showNormal();
		parentWidget()->setGeometry(oldGeometry_);
	}
	else
	{
		oldGeometry_ = parentWidget()->geometry();
		parentWidget()->showMinimized();
	}
}

cn u plz send that code , ....im also hvng same requirement of miniming the dockwidget ,like mdisubwindow........
