[Octave-bug-tracker] [bug #61172] Problems after maximize the GUI with 2 monitors

[Theodore]

Follow-up Comment #51, bug #61172 (project octave):

To fix the issue, it can be firstly set Qt::WindowState::WindowMaximized, then
compute the geometry using for example, QStyle::PM_TitleBarHeight.

The subsequent resizing of widgets will be based on total height - title bar
height, and is not affected.

Just my two cents.

(just perfection extension

will probably affect available screen size.
