public void mouseDragged(MouseEvent e) { //Sample 14: Perform Free Hand Drawing if (DrawMode.compareTo("FreeH") == 0) { if (SecondPoint.x != 0 && SecondPoint.y != 0) { FirstPoint.x = SecondPoint.x; FirstPoint.y = SecondPoint.y; } SecondPoint.setLocation(e.getX(), e.getY()); paint(getGraphics()); } } |
