how do i implement lazy loading in gwt just like the one they have in http://www.smartclient.com/smartgwt/showcase/ and so i would like the whole page to be loaded first and and after that i want all widgets to load

iv tried Gwt.runasync but it aint doing much also i tried using

Scheduler.get().scheduleDeferred(new ScheduledCommand() {
            @Override
            public void execute() {
                loadWidgets();
            }
        });


void loadWidgets() {
        hugeWidgets=load_some_huge_widgets();
        RootLayoutPanel rp = RootLayoutPanel.get();
        rp.add(hugeWidgets);

}
