title: Qt QStackedWidget Resizing Issue
body: <p>I have a simple QStackedWidget with 3 different QWidgets in it. The minimum sizes of the  QWidgets are (350x200), (200x100), and (450x450).</p>
  
  <p>So the problem I'm having is when I resize the QStackedWidget, it has a minimum size of the largest QWidget within it. So if I switch to the second QWidget, (which is the QWidget with the size of (200x100)), the QStackedWidget will only size down (450x450) because of the largest QWidget inside of it. I would like it to size down to fit the current QWidget being displayed, and remove that minimum size.</p>
