[Qt-interest] Mouse events inside item view delegates

[Neville Dastur]

Thank you Andre. I had, but could see how it would help, the 4.6 
documentation is sparse, to say the least. Reading the 4.7 docs (which 
does apply to 4.6.3) it states that even if an editor event does not 
occur, mouse events are still sent to the member function.

For anyone else, this snippet achieves the desired effect:

     virtual bool editorEvent (QEvent *event, QAbstractItemModel *model,
                               const QStyleOptionViewItem &option, const 
QModelIndex &index ) {

         if(event->type() == QEvent::MouseButtonRelease) {
             QMouseEvent *me = (QMouseEvent*)event;
             if (me) {
                 qDebug() << "::editorEvent() mouse release click 
position = " << (me->pos() - option.rect.topLeft());
             }
         } else {
             event->ignore();
         }
     }
