In fact my window derives from QWidget. Changing it to QMainWindow makes it receive mouseMoveEvents without clicking as desired - thank you ! 

However, it does not work if the mouse resides outside the window. So I changed my class back to QWidget and followed your suggestion of creating an extra QMainWindow and set my widget as the central widget via setCentralWidget(); In that context I also overwrote the mouse event handler of the QMainWindow with mouse pos messages. Unfortunately this didn't solve the problem either: Only the central widget's handler fired only when placing the mouse on it and not outside the widget's boundaries.

Did I correctly follow you suggestion or am I possibly mistaken ?

Thanks and best

Alex
