I have a class derived from QGraphicsView
, which contains QGraphicsItem
-derived elements. I want these elements to change color whenever the mouse cursor hovers over them, so I implemented hoverEnterEvent
(and hoverLeaveEvent
):
void MyGraphicsItem::hoverEnterEvent(QGraphicsSceneHoverEvent* event) { update (boundingRect()); }
However, this event handler code is never executed. I've explicitly enabled mouse tracking:
MyGraphicsView::MyGraphicsView(MainView *parent) : QGraphicsView(parent) { setMouseTracking(true); viewport()->setMouseTracking(true); ... }
Still, no luck. What am I doing wrong?
Fixed it. I need to use setAcceptHoverEvents(true)
in the constructor of my QGraphicsItem
-derived class.
