Tutorial: How to listen to all major events of ICY. Painter added/removed, plugin started/closed, roi, focus, viewer (...)

        // add the global event listener
        Icy.getMainInterface().addListener(mainListener);

        frame.addFrameListener(new IcyFrameAdapter()

            @Override
            public void icyFrameClosed(IcyFrameEvent e)
            {
                // remove the main listener so there is no more reference on plugin instance
                Icy.getMainInterface().removeListener(mainListener);
            }
        });

        // add the scroll pane to the frame
        frame.getMainPanel().add(scrollPane);
        // set default size
        frame.setSize(700, 300);
        // add the frame to the interface
        addIcyFrame(frame);
        // center frame
        frame.center();
        // make it visible
        frame.setVisible(true);
    }
}

This class demonstrate how use the MainListener to track global event on Viewer, Sequence, ROI and Painter objects
