I want to get mouse cursor position instantaneously on a widget which is in a graphicsproxywidget; but the mouseMoveEvent is not being called anytime. I put a qDebug inside the event, nothing is written on the console when i run the application. I reimplemented the event in the proxywidget class' definition.
void panelProxy::mouseMoveEvent(QGraphicsSceneMouseEven t *event)
{
qDebug("mousevent");
}
What may be the problem?

have you set QGraphicsItem::setAcceptHoverEvents() to true?

No, i didnt set QGraphicsItem::setAcceptHoverEvents() true; i can use hover events, there is no problem with them. But mouseMoveEvent doesn't work...

The point is: you won't get mouseMoveEvents unless you set the item to accept hover events.

Now, Ive tried to implement the event inside of the widget, not inside of the proxywidget..It works partially know...
void screenWidget::mouseMoveEvent(QMouseEvent *event)
{
qDebug("mouseevent in widget");
}
I moved the cursor for 30 seconds on the screen;but there were just 2 events I could see on the console! What is that know:confused: Shouldn't that event be called every milliseconds I move the mouse?

setMouseTracking is already set true. The question is why is the event being called sometimes;but sometimes not?

I think, i got the problem. I should setMouseTracking(true) for central widget and all child widgets. Isn't there any direct way to make setMouseTracking(true) for all widgets on the scene?

You can set the mouse tracking on the parent widgets if ther is one item in the scene, or iterate on top child items and set it manually
