Set focus to applet in code

[chirs]

Hi,

I have a java applet which will allow user to type in a letter. But
the user has to first click on the applet to set focus. How can I set
focus to applet in code? Here is a part of code:

int m;

public void paint(Graphics g) {
g.drawString("" + (char)m,200,200);
}

public boolean keyDown(Event evt, int key) {
m=key;
repaint();
return true;
}

Thanks
