Panel onClick handler?

I have a Horizontal Panel, when I click anywhere in that panel, I want a dialog box to pop up. However, there doesn't seem to be a click handler for this panel. Any suggestions? thanks

Morning,

you can always add your own Handlers to any panel by calling the addDomHanlder method. The addClickHandler method sim0pliefies that. Here is some sample code for you:

        HorizontalPanel hp = new HorizontalPanel();
    hp.add(new Label("samplelabel 1"));
    hp.add(new Label("samplelabel 2"));
    hp.add(new Label("samplelabel 3"));

    ClickHandler ch = new ClickHandler() {

        @Override
        public void onClick(ClickEvent event) {
            Window.alert("clicked");                
        }
    };

    hp.addDomHandler(ch, ClickEvent.getType());

    hp.setWidth("500px");
    hp.setHeight("500px");

    RootPanel.get().add(hp);

You can read more on the subject under 'Widget Developers' on What's New in GWT 1.6?.

HorizontalPanel has methods addDomHandler and addHandler which you can use to add ClickHandler, e.g.

HorizontalPanel panel = new HorizontalPanel();
panel.addDomHandler(new ClickHandler() {
    @Override
    public void onClick(ClickEvent event) {
        // TODO process event
    }
}, ClickEvent.getType());
