Emulating PyQt's QDockWidget look and feel

[Aerylle Lain]

Really love the extra control pyqtgraph's implementation of docks gives, but was wondering if it was possible to emulate the display of docks so that they look like QDockWidgets? Namely, when you drag docks the entire dock is displayed as moving, and possibly even the allowed areas are shown with other docks "moving aside" like they do in PyQt. Even just implementing the former is fine.

Looking for ideas, or at least where to start, I'd be happy to work out the full implementation myself if anyone can give me a clue about what I should look at/modify first, or if this isn't really compatible with pyqtgraph's implementation of docks. Thanks!
