I use C++, Qt 4.8.7 for creating GUI application under Windows. I have additional main window as a tab (see an image below). A, B, C, D are dockable widgets. How can I put B widget on the top of C widget? I was able to do it via mouse, but I'd like to do it programmatically. I don't want to have tabified docks.
BTW, do I have to create a dummy zero-sized central widget? Are dockable widgets more stable in Qt 5.x? Moving docks within my mainwindow is not comfortable (I've created empty small central widget).
