Re: Preventing selection event propagation

Tab(Layout)Panel's SelectionEvent is a GwtEvent and not a DomEvent, so its only a logical event fired by GWT and not a native event fired by the browser. Thats why you don't have a stopPropagation() / preventDefault() method.

But TabPanel and TabLayoutPanel have an addBeforeSelectionHandler() and the BeforeSelectionEvent contains a cancel() method which should cancel the upcoming selection. This should help you to solve your problem.

Our application has two tabs. On selecting the tabs we have to display
a confirmation window(dialog box). Depending on whether user clicks
"Yes" or "No" button in the confirmation window, the tab selection
event should proceed or stop.

I know we have event.stopPropagation() method for click event. However
there is no such method for selection event.

Is there any work around to stop the propagation of the selection
event. Any help is much appreciated.

Thanks in advance.
