Maximized window goes up and hides the QMenuBar while demaximizing

[darkgaze]

I click the middle button in the menu bar right side buttons. The unmaximize, make it resizable. If i do that, the window goes up to pos 0,0 for the Graphics View, so i cannot move the window, or use any button on the menubar.

On the other hand, if i drag the menubar down it gets out of the maximized mode, but this way i got the window holding it and i can move it, and works superb.

So... how can i reimplement or change the way the menubar middle button (not maximize, not minimize... what is it´s name?) so it doesn´t bring the window to 0,0 ?

Thanks!
