I have an issue and I can't to solve it. It's look simple, but I can't find an answer.

I have created MainWidget which I call in main.cpp. It looks like

MainWidget mw;
mw.showMaximized();

And I see maximized widget. But when I'm trying to get size of mw, I get QSize(800, 600), which is obviously wrong. It looks like widget didn't change his size, just looks bigger (?) when I called showMaximized() method?

Is there any chance to get ACTUAL SIZE of widget? It will be different, depending on screen resolution, which I want to use to resize properly widgets inside MainWindow.

Is there any change to do that? Any help will be good.

    The geometry of any widget in Qt is invalid until the widget gets shown. Override `showEvent` and/or `resizeEvent` and get the geometry there. – peppe Jan 03 '15 at 22:56

QMainWindow::showMaximized() Doesn't Update Size

The questions seems to have been asked multiple times, and each one ends up with something like handle 'resizeEvent'. I don't think that there is a way around it really. Implementing a handler for resizeEvent doesn't seem too hard though. For a some reference:
