This is how you can read stylus events, i.e. get the x,y coordinates of where the pointer is pressed and how to create a key event, i.e. read what button the user has pressed:
In order to draw stuff on screen you'll either use Canvas, LWT or GameCanvas. As LWT and GameCanvas both extend Canvas, you can just implement a key and stylus listener.
Just implement the following methods in your class that draws stuff on screen, i.e. extends an interface mentioned above: (this is an extract from our code, you can implement your own handling)
//this method will be called if the stylus touches the screen at x,y:protected void pointerPressed(int x, int y) {
//do something with the received x,y coordinates current.actionPerformed(new Message(Message.STYLUS, x,y));
}
//this method will be called if the user presses a key protected void keyPressed(int keyState){
//determine whether the input is something we can use or not. boolean flag = true;
switch(keyState){
case -3:
keyState = LEFT_PRESSED;
break;
case -4:
keyState = RIGHT_PRESSED;
break;
case -1:
keyState = UP_PRESSED;
break;
case -2:
keyState = DOWN_PRESSED;
break;
case -5:
keyState = FIRE_PRESSED;
break;
default:
flag = false;
}
//if the data is good, perform the according action if(flag){
current.actionPerformed(new Message(Message.JOYSTICK, keyState));
}
}
