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.
