is showMaximized() guaranteed to show the window?

Is showMaximized() guaranteed to at least show the window on all desktop operating systems?
Is it possible to determine if it failed in any way (via code)?

Nor does X11 provide a way to maximize a window. QWidget::showMaximized() has to emulate the feature. Its result depends on the result of QWidget::frameGeometry() and the capability of the window manager to do proper window placement, neither of which can be guaranteed.

Hi!

Looking at void QWidget::showMaximized() in qwidget.cpp I would say 'yes' because setVisible(true) is called no matter happens before.

Do you know any desktop environment where showMaximized doesn't work?

@Wieland Thanks for the help and the link.

No I do not. I'm contributing to an open source project so I want to be sure.
