Dear Sir,
I use PersonalJava and Nokia SDK 1.1 emulator to test my program.
First, I define a class which extends CFrame and implements CBAListener, Runnable, KeyListener.
Second, I add Keylistener (add.KeyListener(this))in the constuctor of the class and overload the keyPressed(),keyReleased(),keyTyped().
Result, CBAlistener works fine but Keylistener does not work, Moreover, if I use mouse the click the top of the windows of my application. the KeyListener begin to work. I think it should be something related to focus event but I dont know how to handle it.
Please help me.
Code related:

public class Music extends CFrame implements Runnable, KeyListener , CBAListener
{
CBAHandler cba;
public static void main( String args[] )
{
new Music();
}

public Music()
{

cba = new CBAHandler( this );
cba.setText( ADD , "Add " );
cba.setText( CLOSE , "Close" );
cba.activate();
addKeyListener(this);
item.addKeyListener(this);
add(item);/*item is a object extends Canvas*/
show();
}
public void keyPressed(KeyEvent ke){....}
public void keyReleased(KeyEvent ke){....}
public void keyTyped(KeyEvent ke){}
......
}

this.requestFocus();
....
