Disable back button in GWT

Question

Is there a way to disable the Back button in a browser (basically clearing the History token stack) in GWT? Once I browse to a certain page in my application I want to make sure that the user can't use the back button to go back, but only be able to use links on the page to navigate the site.

Answer 1

You cannot disable a button just intercept it and change its return to something the browser does not understand.

This removes the history:

 Window.addWindowClosingHandler(new ClosingHandler() {
     @Override
      public void onWindowClosing(ClosingEvent event) {
      event.setMessage("My program");
      }
    }); 

To understand it see: http://groups.google.com/group/google-web-toolkit/browse_thread/thread/8b2a7ddad5a47af8/154ec7934eb6be42?lnk=gst&q=disable+back+button#154ec7934eb6be42

However, I would recommend not doing this because your it goes against good UI practices. Instead you should figure out a way that the back button does not cause a problem with your code.
