[vtkusers] vtkCommand doesnt exist in Java?

[Gökhan ERSOY]

here is a part of my code. when i write the name of callback function
myCallBack as "myCallBack" in parameter list of AddObserver, it is not
recognized. does anyone have an idea? or is there any faulty statement?

----------------------------------------------------------------------------------------------------------------
public class SimpleTexture {
    ...
   public SimpleTexture() {
       vtkRenderer ren = new vtkRenderer();
       ...
       vtkActor planeActor = new vtkActor();
       ...
       planeActor.AddObserver("LeftButtonPressEvent", this, "myCallBack");
       ren.AddActor(planeActor);
       ...
   }
   ...
   private void myCallBack(){
        System.out.println("Hello");
   }
   ...
   public static void main(String[] args) {
        SimpleTexture simpleTexture = new SimpleTexture();
   }
}
----------------------------------------------------------------------------------------------------------------

Thanks...

Gökhan
