GWT Update Event Detection

Question

We need to define an update event (f5) / web application reload. Is there an event in GWT that can detect this?

thanks MJ

Answer 1

Add a window close handler :

HandlerRegistration registration = Window.addClosingHandler(new ClosingHandler() { void onWindowClosing(ClosingEvent event) { // call the server, or whatever } }); 

EDIT

HandlerRegistration used to unregister Handler if you no longer need it.
