hai Guys,

I have a problem on How to implement keyListener for Canvas Midlet, I have a canvas class the scroll seems doesn't work. I have already put

Application.getApplication().addKeyListener( this ) ;

in canvas class but still no effect at all.

I have 1 question also on How To print out the System.out.println("debug"); on BlackBerry Simulator Output Console.

I Use Eclipse ganyMede and ejde 4.6.0

Thanks for Your help

Regards,

Purbo

Thanks simon_hain I'll try I have to make sure that

keyPressed and keyReleased methods of the current Canvas object are called with the keyCode parameter having a value of Canvas.DOWN. by adding

    protected void keyPressed(int keyCode) {
       
        System.out.println("Keypress : "+ keyCode);

But the system doesn't print anything on console screen windows, is it true that this method wasn't called when I Scroll using trackpad ?

Thanks for Your Answer
