Does anyone what is required to create a dock widget that allows the user to show it, then pin it open if the user so chooses, similar to the behavior of the toolbox in visual studio .Net? I have tried playing with many of the size settings to get the desired behavior to no avail. I would like the dock widget to overlap the central widget when shown (but not pinned), then have the central widget (and any other visible widgets) resize themselves if the widget is pinned. I would hope I can do this all while having the window docked rather than floating, but I don't know if it's possible to have widget overlap when docked. Thanks in advance for any help.
