I have fixed it :-) 

A lot of  thanks to Aldin, for your Ideas and your help. 

And  also to Thomas you have shown me the right way ;-) 

The solution is: There is a closingEvent which is be called when someone want to close the window. 

And there is a CloseEvent which is called when the window realy be closed. 

So my Question is be implementd in the onWindowClosing method and my logoutcode in the onClose method 

Thanks for your help

Yeah that's nice it's something we are looking for. But how do I interupt the thread.

I have implemented this in my webapp but now if the user reload the Page he will also be logged out when he click on "Stay".

Maybe I can attatch a callback or so ?

Window.confirm()?

We use this at the moment but there you can't change the buttons. In this confirm Dialog only "OK" or ´"Cancel" is avaible.

In that specific case, you'll want to Window.addClosingHandler and setMessage on the event.

We also have this handler added and it works well. Butt what do you mean with "setMessage"?

http://google-web-toolkit.googlecode.com/svn/javadoc/latest/com/google/gwt/user/client/Window.ClosingEvent.html#setMessage(java.lang.String)

"Set the message to a non-null value to present a confirmation dialog that asks the user whether or not she wishes to navigate away from the page." 

This is standard JS, the browser is left in control of how exactly it displays the message, but that's the only way to possibly prevent an "unload" of your app.
