I just noticed this also. The DragMove functionality is exactly what I want for
my application. Tried to reimplement the QDragObject::drag but then I didn't
know if a widget had accepted the dragobject or not. Will DragMove be added in
Qt-1.42 or do I have to wait until 2.0? Do anyone here know of a workaround?
