[Octave-bug-tracker] [bug #44776] [Qt] Restore window button does not trigger a repaint event for its content

[Michael Goffioul]

Follow-up Comment #11, bug #44776 (project octave):

Given that a figure can contain a menubar and toolbars, it would be difficult
to inherit from QCanvas or QGraphicsScene. Or you'd need another outer
container. But the fact is that a Matlab figure has a dual personality: it
represents the external window (with a toolbar, a menubar...), and at the same
time it represents the internal container (QMainWindow's central widget; e.g.
"position" property maps to the position of the central widget in global
coordinates; removing the figure's menubar doesn't change the "position"
property, which means you have to move the outer container to keep "position"
constant...). This dual personality makes things more complicated than it
seems.

That being said, you are obviously welcome to rewrite the graphics code using
a state-of-the-art approach.
