[vtkusers] vtkPicker in Java

[Brian Henz]

I have had some varying success with vtkCellPicker in Java.  Use the 
MouseMotionListener to keep track of the current position of the mouse.


class MouseTracker implements MouseMotionListener {
  public void mouseMoved(MouseEvent e){
    //  sharedrenpanel is the vtkPanel
    guiLocationX = e.getX();
    guiLocationY = sharedrenpanel.getHeight() - e.getY();
  }
}

// Then to get the Pick information start here and call
//   functions as needed such as GetCellId, ...
Integer x = new Integer(guiLocationX);
Integer y = new Integer(guiLocationY);

// sharedren is the vtkRenderer for the vtkPanel
myPicker.Pick(x.doubleValue(), y.doubleValue(), 0.0, sharedren);
int myCell = myPicker.GetCellId();
