Revision history [back]

I am creating a bunch of components dynamically in java - add manually creating event listeners for them as follows:

Idspace linkWrapper = new Idspace();
linkWrapper.setSclass("link-wrapper");

Button linkButton = new Button();
linkButton.addEventListener(Events.ON_CLICK, new org.zkoss.zk.ui.event.EventListener() {
    @Override
    public void onEvent(Event event) throws Exception {
    ...
    }
});
linkWrapper.appendChild(linkButton);

Do I have to remove all of the event listeners for these buttons manually or will

linkWapper.getChildren().clear()

remove all of the event listeners for me ?
