I'm not sure about why that's not working... can you write a smallish piece
of code for all of us to look at?
Also, perhaps installSceneEventFilter would be easier to use?
It would look something like this:
foreach (QGraphicsItem *child, A->children())
{
child->installSceneEventFilter(A);
}
-and-
bool A::sceneEventFilter(QGraphicsItem *watched, QEvent *event)
{
if (event->type() == QEvent::QGraphicsSceneMousePress)
{
// ... do watcha gonna do
// maybe store away what item was pressed?
m_item_i_am_watching = watched;
}
return false; // Event is sent to the child.
}
