On Mac OS and Windows, the spin box is placed next to the cursor and 
moves with it. On X11, I had to disable that because there is a problem 
embedding widget items if the flag Qt::WA_PaintOnScreen is set on the 
canvas.
But yes, it might be better to have a separate window on X11.

It is intended that editing changes the result. After pressing the 
return key, the offset line should move to the new distance (but the 
mouse should not be moved, otherwise it will be overriden by the 
following mouse move position). Doesn't this work for you?

Regards,
Marco
