Maybe I don't have the dock widget's properties set correctly?

I've kind of decided to leave the dock widget on the left for aesthetic reasons, and I can get a layout I like if "docked" isn't checked. As soon as I check docked, the QDockWidget reverts to its original size and position.

Also, any advice as to how to do the following would be appreciated:

- Dock widget on upper left, resizes horizontally and vertically as the main window is dragged. (This contains an Open Inventor SoQtRenderArea.)

- Controls (buttons, etc.) below the dock widget, and to the right of the dock widget. These should stay fixed in size; the main window shouldn't be able to get smaller than the controls.

I'm looking at the Examples and Demos, but don't see anything that helpful done in Designer.

Thanks in advance,
Martin
