title: Forcing an Aspect Ratio when resizing a main window
body: <p>I understand that in Qt4, there is no single flag you can set to have the mouse driven resizing of the window maintain a certain aspect ratio (say, 1:1). Is there a way to force a new size for the window while in "resizeEvent (QResizeEvent * event)"? the parameters of the event don't seem to support change or give the user a chance to inject a new size.</p>
  
  <p>My goal: GUI/Mouse resizing of a certain window will maintain its current aspect ratio, regardless of where you resize it from (sides, top, bottom, corners).</p>
