How do i cancel the close event from a SmartGWT Window?

How do i cancel the close event from a com.smartgwt.client.widgets.Window ? I need the user confirmation to close the window, i saw that the class com.smartgwt.client.widgets.tab.events.TabCloseClickEvent have a cancel method that stops the action, i need the same for the com.smartgwt.client.widgets.events.CloseClickHandler. How do i implement this feature?

I found that if you don't immediately cancel the event (because it's waiting for user input) then the window closes anyway. Here is what I found worked if you need to wait for user input.

window.addCloseClickHandler(new CloseClickHandler() {
        @Override
        public void onCloseClick(CloseClickEvent event) {
            event.cancel();
            StringBuilder b = new StringBuilder();
            b.append("<BR>");
            b.append("Are you sure you want to close?");
            SC.ask("Close", b.toString(), new BooleanCallback() {
                @Override
                public void execute(Boolean value) {
                    if (value) {
                        window.close();
                    } 
                }
            });
        }
    });

In your window object

    myWindowObject.addCloseClickHandler(new CloseClickHandler() {  
            public void onCloseClick(CloseClickEvent event) {  

                    //Do whatever

                    if(IHaveTOCancel){
                            event.cancel();
                    }
                }  
            });

public HandlerRegistration addCloseClickHandler(CloseClickHandler handler)

Handles a click on the close button of this window. The default implementation hides the window and returns false to cancel bubbling. Override this method if you want other actions to be taken.
