Hi ,

HoopsWidget::HoopsWidget (QWidget* parent, const char* name)
: QWidget (parent, name)
, event_item_ (0)
, must_update_on_repaint (true)
{
setFocusPolicy (Qt::ClickFocus);
setMouseTracking (true);
setBackgroundMode (Qt::NoBackground); // avoid flicker
}

here Hoopswidget is class. after creating HoopsWidget object, I have set the graphics view using hoops API to draw the geometry. when i just resize the window the graphics view resized but window background overlap the graphics view.

I don't know Hoops but a quick search returned "this":http://docs.techsoft3d.com/visualize/3df/latest/HoopsQt/ProgrammingGuide_C.html might be a good start

Hi ,

I have found that continuously updaterequest(event no 77) event is going to fire for that widget.
so i just set setUpdatesEnabled(false) then the flickering problem goes off.
