 In trying to make the layout of may activity adapt to both fullscreen mode
 and screen rotation, I have been frustrated by the lack of documentation.
 I have observed a private variable in window.py that maintains the status
 the fullscreen mode, but don't know how to access it. There is an OLPC-
 specific mechanism for detecting screen rotation in olpc-kbdsm, but it is
 not documented, as far as I can tell, and it would be useful to have a
 mechanism in general for notifying Sugar activities that something has
 changed.

 walterbender    garycmartin: is there an activity you can recommend as an
 example of good handling of screen rotation?
         garycmartin     walterbender: example of good handling of screen
 rotation; no not specifically. Most do a fair job relying on standard gtk
 widget auto-scaling. I can't think of any off the top of my head that try
 and detect a change and do something more advanced (e.g. Calculate could
 auto switch between basic and scientific mode, or Read could auto switch
 between 1 column or 2 column book page layouts).
         walterbender    garycmartin: how to detect the change is not well
 documented...
         garycmartin     walterbender: agreed
         walterbender    garycmartin: I cannot even find doc on how to know
 if I am in fullscreen mode or not (I know when I enter, but not when I
 leave unless I access an internal variable in window)
         manuq   walterbender: maybe kbdism can be wrapped in a signal?
         walterbender    manuq: +1
         garycmartin     walterbender: I did consider at one point looking
 at the canvas aspect ratio to decide on portrait vs landscape when a
 canvas redraw was triggered, but I didn't have a good need for it back
 then.
         walterbender    manuq: are there any code snippets as to how to
 use kbdsm?
         manuq   walterbender: you could start reporting a bug for
 enhacement
         manuq   walterbender: not that I know
         walterbender    manuq: will do
         manuq   walterbender: great
