[vtkusers] SetStartMethod/SetEndMethod in vtkProcessObject ?

[Oliver Vidovic]

 Hi,

 I found out that (in Java), vtkProcessObject's methods SetStartMethod and
SetEndMethod use as parameters: callback object as Object, and the name of
the method that will be called on the callback object as String.
 This works as long as the vtkProcessObject is a 3D process object (e.g.
vtkPolyDataMapper).
 Any idea why this would not work with 2D process objects (e.g.
vtkTextMapper, vtkPolyDataMapper2D) ?


 thanks
