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

Answer 1

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

That is not a fool proof solution. In fire fox I can press the back button and the onWindowClosing method is never invoked. The reason is that I have used History.newItem() and since history exists the back button or backspace buttons simply navigate through the browser history.

So....fix that :)
