    • Method Detail

      • mouseDragged

        public void mouseDragged​(LayerEvent e)
        Invoked when the mouse moves while the button is still held down.
        Specified by:
        mouseDragged in interface LayerListener
        Parameters:
        e - The event

        Invoked when the mouse moves while over a layer or figure.
        Specified by:
        mouseMoved in interface LayerMotionListener
        Parameters:
        e - The event

      • mousePressed

        public void mousePressed​(LayerEvent e)
