promote PyQt5 QDockWidget to pyqtgraph.dockarea.Dock

[Tim Williams]

Hi.

Very new to both PyQt and pyqtgraph. Is there a way to promote a QDockWidget to a Dock widget in pyqtgraph?  I've seen the example in 

http://www.pyqtgraph.org/documentation/how_to_use.html#embedding-widgets-inside-pyqt-applications

but I don't see how to do this for Docks. I want to be able to use QtDesigner to set up a  *.ui file, but also be able to use the more capable Docks in pyqtgraph.

Thanks for any help.

The DockArea doesn't extend QDockWidget, only QWidget.  So you could promote a QWidget, except for the fact that this assumes the constructor can take a single non-keyword argument and assume it to be its parent, which is not the case for DockArea.  I've got a PR to fix this here:

Thanks for the quick reply. I tried extending a QWidget after failing with QDockWidget. I wasn't sure if I sure promote to a Dock or a DockArea. (Looks like I can't get there from here yet anyway though.) I'll wait and see how your PR shakes out.
