Strange performance of QDockWindow?

[luffy27]

I have a MainWindow subclassed by QMainWindow, and also a QDockWindow on the bottom of the MainWindow. Then I add a QWidgetStack into the QDockWindow. The QWidgetStack contains two QHBox. Each QHBox is a toolbar. Finally, I want to switch on/off between the two toolbar by clicking a toolbutton, that is why I use a QWidgerStack in the QDockWindow.

However, despite of the swicth on/off functionality, the QDockWindow has a ridiculous presentation or performance, it can not show correctly!

Below is my code, Please Help Me!

Wouldn't it be simpler to use regular toolbars? QToolBar inherits QDockWindow so you can use it just like a dock window and you can use show() and hide() to switch between toolbars without a widget stack.

[luffy27]

Is there any functions like show() or hide() supplied by QToolBar?
Ok, I will try it.

But by the way, I have solved the problem by adding this:
toolBarDockWindow->setWidget(toolBarStack);

Thanks a lot!

Yes, QToolBar inherits QWidget.

toolBarDockWindow->setWidget(toolBarStack);

Using show/hide will give you much cleaner code, especially if you use setShown()/setHidden() which are slots, so that you'll be able to connect them to actions that can trigger those changes.

All right, I will try it.
Thanks a lot!
