it's less overhead to use the ItemStateListener than the ActionListener. - sorry that I have not mentioned it in the first mail. I didn't think of it by then. the itemstatelistener is only notified if the selection changes, while the actionlistener is notified even if the checkbox is already selected and gets clicked a second time.
