title: PySide QTabWidget resize event
body: <p>LS
  I have a widget on a tabsheet. During setup of the app window the size of the tabsheet is used to determine the size for the widget. The widget size is then set to fully cover fill the tabsheet. When I resize the window the tab is also resized, but the widget remains at the original size (as from the initialisation). I would like a recalculation for the size of my widget so it can be set to a new size after the tab size has been changed.
  I need a trigger that captures a window resize event and then do the widget size recalculation. How can this be done ?
  Tnx</p>
