KeyListener of JComboBox

[qunfeng wang]

I add a KeyListener to my comboBox. But When I edit an item of my comboBox(Of course, there are key typed, pressed, released events occured), but no event invoked.
If I use the KeyListener in a wrong way why do a keylistener be added to a comboBox.
Thanks in advance.
PS:If I don't describe it clearly, please let me know.

in the absence of any code which demonstrates the problem, I will guess

if you are adding your keylistener like this
comboBox.addKeyListener(...

it should be
comboBox.getEditor().getEditorComponent().addKeyListener(...

Thank you
It works!
Why don't write this in the java tutorial? Or I've not read it?
