Problem with QGraphicsScene mouse move event

[wysota]

QGraphicsSceneMouseEvent::button() returns the mouse button that causes the event to happen. Since mouse movement is not related to pressing a mouse button, button() probably returns Qt::NoButton. Try this instead:

if(e->buttons() & Qt::LeftButton) { ... }

if(e->buttons() & Qt::LeftButton) { ... }

Works like a charm. Thanks, wysota
