Capture mouse cruising events (buttons not pressed)

[novaktamas]

I have a

@ZoomPan_GrView::ZoomPan_GrView(QWidget* parent) : QGraphicsView(parent) { //my subclassed QGraphicsView
@

where I can zoom and pan my graphicsview through mouse event handlers:

@virtual void mousePressEvent(QMouseEvent* event);
virtual void mouseReleaseEvent(QMouseEvent* event);
virtual void mouseMoveEvent(QMouseEvent* event);
virtual void wheelEvent(QWheelEvent* event);
virtual void resizeEvent(QResizeEvent* event);
@
but I want to display the mouse's scene coordinates when mouse simply cruising over the graphicsview.
All the above events depends on mousebutton press.

I tried MouseGrabArea and grabMouse() etc. but all I produced were various and impressive crashes:))
How to grab mouse coordinates when just moving over the graphicsview?

Did you enable mouse tracking on the viewport?

Thank you, Peppe, this was the problem.
If I

QGraphicsView::setMouseTracking(true)

than got the

mouseMoveEvent(QMouseEvent* event)

invoked.
