You could do it this way:
have to int members iny our class
int m_lastX, m_lastY

in the mouse move envet handler you can do something like this:
(assuming event is a QMouseEvent*

int dX =3D m_lastX - event->x();
int dY =3D m_lastY - event->y();
m_lastX =3D event->x();
m_lastY =3D event->y();

hth,
