QDockWidget Size

[kiker99]

Hallo,

i'm trying to convince a QDockWidget to resize itself to a proper size, but it alway takes away half of the window size. (at the bottom)

It would be perfect if the QDockWidget resized itself always in a certain relation to the total size of the Window (as 1/4).

I tried this, but it didn't help. A resize() also doesn't have any effect (I think because of the QLayout)

EDIT: think of setVerticalPolicy where there's setHorizontalPolicy down there. It doesn't make any sense in the other way. What do I need to set for SizePolicy if I want him to use VerticalStretch?

QSizePolicy sizePolicy2;
	sizePolicy2.setVerticalStretch(3);
	sizePolicy2.setHorizontalPolicy(QSizePolicy::Expanding);
	centralWidget2->setSizePolicy(sizePolicy2);
	//chat erstellen
	dockwidget=new QDockWidget(this);
	dockwidget->setAllowedAreas(Qt::AllDockWidgetAreas);
	addDockWidget(Qt::BottomDockWidgetArea, dockwidget);
	chatwidget=new Chat(dockwidget);
	dockwidget->setWidget(chatwidget);
	QSizePolicy sizePolicy;
	//sizePolicy.setHorizontalStretch(3);
	sizePolicy.setHorizontalPolicy(QSizePolicy::Minimum);
	sizePolicy.setVerticalStretch(1);
	dockwidget->setSizePolicy(sizePolicy);

QSizePolicy sizePolicy2;
	sizePolicy2.setVerticalStretch(3);
	sizePolicy2.setHorizontalPolicy(QSizePolicy::Expanding);
	centralWidget2->setSizePolicy(sizePolicy2);
	//chat erstellen
	dockwidget=new QDockWidget(this);
	dockwidget->setAllowedAreas(Qt::AllDockWidgetAreas);
	addDockWidget(Qt::BottomDockWidgetArea, dockwidget);
	chatwidget=new Chat(dockwidget);
	dockwidget->setWidget(chatwidget);
	QSizePolicy sizePolicy;
	//sizePolicy.setHorizontalStretch(3);
	sizePolicy.setHorizontalPolicy(QSizePolicy::Minimum);
	sizePolicy.setVerticalStretch(1);
	dockwidget->setSizePolicy(sizePolicy);
