[harshkurra21]

i write a given code for using navigation key but in s40 devices instead of navigation key 2,5,8 key produce the respected event

protected void keyPressed(int key) {
if (getKeyCode(DOWN) == key) {

x = x + 1;
if (x >= 3) {
x = 3;
}


repaint();
}

if (getKeyCode(UP) == key) {

x = x - 1;
if (x <= 0) {
x = 0;
}

repaint();
}
if (getKeyCode(FIRE) == key) {
if (x == 0) {
as.display.setCurrent(as.form);
}
if (x == 1) {
as.display.setCurrent(as.formm1);
}
if (x == 3) {
as.destroyApp(true);
as.notifyDestroyed();
}
}
}

Hello harshkurra21,

based on the MIDP specification:

"...the class Canvas has methods for handling abstract game events. An implementation maps all
these key events to suitable keys on the device. For example, a device with four-way navigation and a select
key in the middle could use those keys, but a simpler device may use certain keys on the numeric keypad (e.g.,
2, 4, 5, 6, 8).

So based on your findings it seems that the numeric keypad is used in the Series 40 devices accordingly the definition of the specification. I presume this is due to backward compatibility purposes mainly, need to check this further to ensure.

Are you using full-screen mode or normal mode for your Canvas?

If you are using the normal mode, please check whether using the full-screen mode helps:

Canvas yourCanvas;

..

yourCanvas.setFullScreenMode(true);
