The MultipointTouchEvents MIDlet consists of two classes:
MultipointTouchEventsExample
ColorCanvas.
The MultipointTouchEventsExample is the MIDlet
main class. It displays the ColorCanvas.
The ColorCanvas class handles touch events and
draws the worm-like animations on the screen. The worm-like animation
consists of diminishing circles, which are implemented using the nested Point class. The Point class has attributes x, y, and state, the latter
of which is either Point.PRESSED, Point.DRAGGED, or Point.RELEASED.
For information about implementing the MIDlet, see section Implementation.
