The event handlers that handle the movement of the stylus on the PDA display are penDown, penMove, and penUp.
The penDown() method is invoked if the user places the pen on the display. It passes the X and Y coordinates of the point at which the stylus was placed on the display.
public void penDown( int x, int y )
The penMove() method is invoked if the user moves the pen over the display. The X and Y coordinates define the current position of the pen.
public void penMove( int x, int y )
The penUp() method is invoked if the user removes the pen from the display. It passes two parameters, the X and Y coordinates of the point from which the pen was removed.
public void penUp( int x, int y )
