How to add one warning msg before close CTabItem/CTabFolder [message #1771266]

I have one stand alone Java SWT application and CTabFolder and CTabItem items were used. When user try to close one CTabItem by click on "X" icon beside CTabItem title, I want to pop up one window and give user option to cancel this action. No idea how to do it. Don't know how to add listener to CTabItem. I can add one listener for CTabFolder and orverride close function, but I only can do some thing before closing. I can not cancel this action. Thanks. Gary

folder.addCTabFolder2Listener(new CTabFolder2Adapter() {
	@Override
		public void close (CTabFolderEvent event) {
		    System.out.println(" Open popup window here, and do some thing");
                    System.out.println("can not cancel this action ?");
       }
}

Many SWT events have a special flag called "doit". Setting its value to false prevents further processing of the listener chain.
DId you try CTabFolderEvent.doit = false in your close method?
