[Seaside] getting the browser's screen resolution?

Hi Lukas. Since most methods in Seaside are undocumented, and it seems difficult to deduce what should I do from what you wrote, can you show me how to get those current values (how to trigger the callback to set weight and height)?

There is no difference to PHP, JSP, RoR, ... whatever. You can
basically take any solution from there and take it over to Seaside.

If you use Scriptaculous something like that might work for you:

html script: (html request
    callback: [ :value | width := value ] value: (SUStream on:
'window.innerWidth || document.documentElement.clientWidth ||
document.body.clientWidth || 0');
    callback: [ :value | height := value ] value: (SUStream on:
'window.innerHeight || document.documentElement.clientHeight ||
document.body.clientHeight || 0'))

This generates a new request posting the current values into your
web-applications.  Maybe nicer would be to override #initialRequest:
and do a redirect posting the size, but that wouldn't be that simple
