[vtkusers] modify a text in the renderer with the mose move event

[Jérôme]

Hi,
Please "Reply all" when you answer, so that me, David and anybody interested
could follow the *whole* thread!

Well, if you remove your text actor after creating it, you certainly won't
have text displayed...
For the first solution, you obviously have to memorize the previous added
actor, then you can remove it when you want:
It seems that you dont use the Object Oriented capability of python, so you
can forget the second solution.
