Custom item - get key code?

[mikecotic]

i got this in my custom item

private int key;
protected void keyPressed(int keyCode) {
key = keyCode;
this.repaint();
}

how do i know what key is "int key" ? like num key 6 or the key with the "c" letter?

why are not there any enums or something in j2me?

Hi mikecotic,

just check the CustomItem getGameAction() method and the game action constants defined in Canvas JavaDocs: by using these, you can easily check which key was pressed.

this wont work ...

    private int key;
    protected void keyPressed(int keyCode) {
        key = keyCode;
        if(Canvas.GAME_C ==keyCode)
        {
            //the "C" key was pressed , usally responisble for deleting
            //content / items . 
        }
        this.repaint();
    }

You have two errors in your code:

* you have to retrieve the game action from the keyCode argument of the keyPressed() method, like this:

int gameAction = getGameAction(keyCode);

and you have to use it when comparing with Canvas game action constants.

* GAME_C does not represent the delete key, but is a generic "C" game button. Delete button has not an associated game action, so you have to implement a different mechanism to identify it. Here's a key codes table that could be useful:
