[Solved] QGraphicsView mousePressEvent and selection behavior?

maherali

Hi
I'm new to Qt framework, I re implemented the mousePressEvent to place a custom item on the scene , but the problem is now, I can't select the items with single click, I can select it using only double click, I can't select a group by dragging the mouse to draw selection rectangle.

should I implement all these functions again to make it work with single click?
@void YPeersView::mousePressEvent(QMouseEvent event)
{
QPoint p=event->pos();
QPointF pf=mapToScene(p);
YPeerNode * node=NULL;
switch(getPeersViewState())
{
case YCore::PeerScenarioStateAddNode:
addNode(pf);
break;
case YCore::PeerScenarioStateAddConnection:
break;
case YCore::PeerScenarioStateRemove:
break;
case YCore::PeerScenarioStateSelect:
node=(YPeerNode) scene()->itemAt(mapToScene(event->pos()));
if(node && node->isEnabled() && node->flags() & QGraphicsItem::ItemIsSelectable)
node->setSelected(!node->isSelected());

    break;
default:
    break;

}

QGraphicsView::event(event);
}@

I've sent the event to the parent but it's not working.

Should QGraphicsView::event(event) be instead QGraphicsView::mousePressEvent(event) in the case you want the default handler?
