Ah, well, answers that question anyway.; thanks.

Not a problem; this particular "dock" isn't floatable either. The only 
reason I'm even using QDockWidget, really, is because I want this:

   ┌──┬────────────────┐
   │  │                │
   │  │                │
   │  ├────────────────┤
   │  │                │
   └──┴────────────────┘

...and not this:

   ┌──┬────────────────┐
   │  │                │
   │  │                │
   ├──┴────────────────┤
   │                   │
   └───────────────────┘

...where the bottom panel is (also) a QDockWidget. (In that case, one 
that *can* be floated or closed.) In all other respects, though, I want 
the side panel to be a fixed UI element.
