hi all,

I am facing a problem in selecting the items in a qlistwidget.
Actually i have a class which inherit qlistwidget and i am showing the items
in icon mode .
here in this custom widget i am showing a rubberband like this :

void MyWidget::mousePressEvent(QMouseEvent *event)
 {
     origin = event->pos();
     if (!rubberBand)
         rubberBand = new QRubberBand(QRubberBand::Rectangle, this);
     rubberBand->setGeometry(QRect(origin, QSize()));
     rubberBand->show();
 }

 void MyWidget::mouseMoveEvent(QMouseEvent *event)
 {
     rubberBand->setGeometry(QRect(origin, event->pos()).normalized());
     setSelection(QRect(origin,e->pos()).normalized(),QItemSelectionModel::Select);
//setSelection(rubberBand->rect(),QItemSelectionModel::Select );



 }

 void MyWidget::mouseReleaseEvent(QMouseEvent *event)
 {
     rubberBand->hide();
   }


here all things goes fine but no item is selected .
I am unable to understand why this is happening .
Please help me on this issue .

Thanks in Advance.
