How to close IFeedback in Wicket?

Question

I have an IFeedback component on my html, and it shows messages if something happens, etc: I upload a file, and a message will inform me: 1 file upload successfully. And what I want is to close this message peace. How could I do it? If I refresh the page, the message will disappear, but I want to create a button, or a link, to click on it, and than the message will close/disappear. Can anyone give me an example, or some help?

You can add an AjaxEventBehavior that add's a click handler to your component and when it's clicked it will disappear. Here example code with an FeedbackPanel:

private FeedbackPanel feedbackPanel() {
    final FeedbackPanel fb = new FeedbackPanel("feedbackPanel") {
        @Override
        protected void onConfigure() {
            super.onConfigure();
            setVisible(anyMessage());
        }
    };
    fb.add(new AjaxEventBehavior("click") {
        @Override
        protected void onEvent(AjaxRequestTarget target) {
          fb.setVisible(false);
          target.add(fb);
        }
    });
    fb.setOutputMarkupPlaceholderTag(true);
    return fb;
}
