[Qt-interest] Performance issues with setParentItem() API.

[trinathpujari]

Hi All,

          I have a problem in using setParentItem(this) in the 
QGraphicsItem which uses QGraphicsScene.
          Whenever i uses this setParentItem( ) and setVisible(true) for 
a widget after switching the screens for the widget, board is hanging.
          Can anybody knows, how to implement parent and child 
relationship with out using setParentItem( ).
          I think this API (setParentItem( )) has some performance issues.
          Please tell me, if any other way of using setParentItem,

Thanking in Advance...

Regards
 Trinath
