I am using QDockWidgets and placing two of them on the left side of my application so that tabs can be used to select between them. However, Qt\'s default behavior for this
I think, Tom was not too far away from a solution:
You can set your own Widget as title bar:
myDockingWidget->setTitleBarWidget(myTitleBar)
If you design this widget to not show the dock window title, you have it. Via the signal QDockWidget::topLevelChanged your docking widget can even become informed, when it gets floating, so you could then enable the title in myTitleBar again.
