[Interest] QGraphicsScene mouse move event

[Marc Ferland]

Hi,

Quick question about QGraphicsScene::mouseMoveEvent(...):

I only receive a mouse move event when the left mouse button is
pressed. For example, this code:

void MyScene::mouseMoveEvent(QGraphicsSceneMouseEvent *event)
{
qDebug() << "Scene mouse move event";
if (!something)
{
QGraphicsScene::mouseMoveEvent(event);
return;
}

// Do somehting each time the mouse moves over the scene rect.
}

prints "Scene mouse move event" only when I press the left mouse button
and move the mouse.

Is this normal behavior? Should I reimplement the mouseMoveEvent from
QGraphicsView instead? This is kinda strange...

Regards,

Marc

Hi Marc,

Have a look at QWidget.setMouseTracking.
