[vtkusers] vtkTransform::Pop() and vtkTransform::Push()

[Maarten Beek]

Hi all,

I am trying to get some king of 'undo' feature in my interactor style, so that Ctrl-Z would undo the last transformation to the currently selected actor. I am currently looking at vtkTransform::Push()) and Pop(), but haven't been able to get something working. 


Any suggestions?

Another way of phrasing my question would be: How am I supposed to use the Pop() and Push() functions?


Thanks - Maarten
