Don't know what exact interaction you are trying to implement. However,
I guess that you can easy do in Java without vtkInteractorStyleUser. You
can implement custom interaction using standard Java mouse listeners.
Take a look at source code for vtkPanel.java for examples of using
MouseListener, MouseMotionListener, and KeyListener to implement
interaction with VTK. You can use MouseAdapter, MouseMotionAdapter, or
KeyAdapter is you need to implement individual listener methods rather
than full listener interfaces.

You can also use Interactor's AddObserver method of to customize
interaction. Illustrations of that are in Java examples ImageInteractor,
BoxWidget, TransformWithBoxWidget, VolumeRenderWithBoxWidget,
AnnotatePick, and SpherePuzle. Java VTK examples are available from
http://ij-plugins.sourceforge.net/vtk-examples

BTW: I do not see use vtkInteractorStyleUser in any VTK Tcl or Python
examples. Can you point some specific example code?
