[vtkusers] vtkImplicitPlaneWidget + Java.

[Shyam Prakash]

If adding observer is what you are looking for, then

Suppose you want to invoke the method updatePlanePosition() which is in
the class PlaneWidgetObserver then

PlaneWidgetObserver planeObserver = new PlaneWidgetObserver();
pw.AddObserver("AnyEvent", planeObserver,"updatePlanePosition");

You can replace "AnyEvent" with the suitable event to meet your needs

In fact, i want attach an Observer ( pw.AddObserver(...); ) Have a look
on vtkImplictPlaneWidget.py for more details :-(
