[vtkusers] Problem of vtkPointWidget test

[Xiaopeng Yang]

Thanks very much. It works. I put the setposition after placewidget().

By the way, do you think whether I can use a picker in the interaction to
pick up the position of a point that I move to a new place?

Best,
Xiaopeng

just tried it and adding a simple pointWidget.SetPosition(10,0,0)
solves the problem.

perhaps you called called pointWidget.PlaceWidget() after
SetPosition() which then resets the position to the center of the
geometry!?
