java - How to add close button in GWT -


i've code:

... menubar options = new menubar(true); options.additem("first label", new scheduledcommand()         {         @override             public void execute() {              popuppanel popupproperties = new popuppanel();             tabpanel tabpanel = new tabpanel();             flowpanel flowpanel = new flowpanel();             ...             flowpanel.add(...);             scroll = new scrollpanel(flowpanel);              tabpanel.add(scroll, "first tab");             popupproperties.add(tabpanel);              rootpanel.get().add(popupproperties);             popupproperties.center();             popupproperties.show();             }         } ...

if add simplepanel button (close) popupproperties, doesn't work. how can it? lot.

use verticalpanel , add popup-panel. add tabpanel , button verticalpanel.

and don't add popup-panel panel. use center() show it.
