Since then I checked the QualityDashboard a couple of times, but it
doesn't seem to be that you
made the changes yet. I'm not trying to hurry you, but.... ;-)
I think it isn't very hard to implement. If you want me to do it, please
let me know, and I'll
do it right away.

Furthermore I have another question concerning picking. You can give the
pickers have a
StartPickMethod, a PickMethod and an EndPickMethod, but you can give a
vtkProp only a
PickMethod. I would like the vtkProp to have a StartPickMethod and an
EndPickMethod as well,
'cause I could realy use them.

best regards, and keep up the good work,
