GWT notification widget?

Question

do you know if there is any notification widget for GWT out there, like this one here?

AFAIK there is no such widget in core GWT, but why not roll your own:

public class DelayedPopup extends PopupPanel {

    public DelayedPopup(String text, boolean autoHide, boolean modal) {
        super(autoHide, modal);
        setWidget(new Label(text));
    }

    void show(int delayMilliseconds) {
        show();
        Timer t = new Timer() {
            @Override
            public void run() {
                DelayedPopup.this.hide();
            }
        };

        // Schedule the timer to close the popup in 3 seconds.
        t.schedule(3000);
    }
}

This is out of my head so it might not compile, but you get the idea.

Update:

As per comment, I'm adding notification that hides itself on mouse move:

public class Notification extends PopupPanel {

    public Notification(String text) {
        super(false, false);
        setWidget(new Label(text));
    }

    @Override
    public void show() {
        installCloseHandler();
        super.show();
    }

    public native void installCloseHandler() /*-{
        var tmp = this;
        $wnd.onmousemove = function() {
            // edit the com.google.gwt.sample.contacts.client package 
            // to match your own package name
            tmp.@com.google.gwt.sample.contacts.client.Notification::hide()();
            $wnd.onmousemove = null;
        }
    }-*/;
}
