  * on bigger resolutions this class will help you.
  * You can add as many widgets you want to it. Set a poliy on which width/height it
  * should switch the layout.
  * You can either say to place widgets vertical or horizontal.
  * This class uses QHBox, QVBox and QTAbWidget internally.
  * OSplitter takes ownership of the widgets
