[wagmare]

use eventFilter() and filter the mouse events ...

bool myGraphicsView:: eventFilter(QObject *ob, QEvent *e)
{
        if(ob == item_need_filter && e->type() == QEvent::MousePress /**any event u want to filter**/) {
                .......
                }
                return true;
        }
         return QWidget::eventFilter(ob, e);
}

bool myGraphicsView:: eventFilter(QObject *ob, QEvent *e)
{
        if(ob == item_need_filter && e->type() == QEvent::MousePress /**any event u want to filter**/) {
                .......
                }
                return true;
        }
         return QWidget::eventFilter(ob, e);
}
