I am using Qt 4.6.3 with Windows 7 with Multi-Touch hardware. I am
creating a QGraphicsObject that receives QGestureEvents using the
following function:
bool MyGraphicsObject::sceneEvent(QEvent* pEvent) {
switch (pEvent->type()) {
case QEvent::TouchBegin: // Needed to get around potential Qt
bug
pEvent->accept();
return true;
case QEvent::Gesture:
std::cout << "Gesture Event Received from sceneEvent()"
<< std::endl;
pGestureEvent->accept();
return true;
}
return QMapItem::sceneEvent(pEvent);
}
However, those events are still getting passed to viewport because my
QGraphicsView is receiving them as well via:
bool MyGraphicsView::viewportEvent(QEvent *pEvent) {
if(pEvent->type() == QEvent::Gesture) {
std::cout << "Gesture Event Received from
viewportEvent()" << std::endl;
pEvent->accept();
return true;
}
return QGraphicsView::viewportEvent(pEvent);
}
It seems to me that if the QGraphicsItem receives a gesture, the
gesture should not be passed to the viewpoint unless the QGraphicsItem
passes the event to its super class. Is that correct? Is there a way
for me to make this happen?
Thank you for your help.
