keyPressed: JList is shown and selects corresponding entry. How?

I have a Component with a KeyListener. When the user types a key, say x, a
sorted JList in a JDialog shall pop up and immediately select the first X
entry.

How can I do that? I have already added a KeyListener that listens for a
typed char and pops up the dialog with the list. But now, I have to
propagate the key to the list so that it selects the right entry,
according to what the user has typed.

sth like this:

addKeyListener(new KeyAdapter() {
public void keyTyped(KeyEvent e) {
dialogWithJList.setVisible(true);
// now sth like:
dialogWithJList.getList().fireKeyPressed(e)
}
});

Maybe I could loop over the elements in the list and get the index of the
first X entry and select it.
But there should be a way to just bring the keyEvent that the user has
generated, forward to the JList.

thanks
Andi

It should be dispatchEvent, right? It's supposed to dispatch the keyEvent
to the JDialog. But it does not work

dialogWithJList.dispatchEvent(new KeyEvent(
    dialogWithJList,
    e.getID(),
    e.getWhen(),
    e.getModifiers(),
    e.getKeyCode(),
    e.getKeyChar()
));

Why? What can I do?
