I need separate hide and the clock on the "x" button because different things shall happen in my application.

Tried with that subclassing example in the mentioned thread, but I can not access the closeBtn so how can I access the close button if I subclass WIndow or Dialog?

If you app clothes the window automatically, than it is in another state as if the user clothes the window. Your controller/presenter whatever should easily be able to find out what happend due to the state of your app.

Also as the closeBtn is protected, it should be easy to use it in a subclass. Also if it would be private, you could JSNI to access it

You could also disable the events completly if you close it manually and enable them after it.

Than you can call your listener also manually.

the closeButton is private. Did it with a different state, but it's not as intuitiv as I thought first

Than you are using an older version. You can however also use JSNI to access private members..

It depends on how you structure the code. I never use the presentation layer to distinguish between different states
