[Notion-devel] Notion and EWMH virtual desktops

[Arnout E. <no...@bz...>]

Hi,

EWMH ( http://standards.freedesktop.org/wm-spec/wm-spec-latest.html#id2533861 
or http://developer.gnome.org/wm-spec/ ) has a notion of 'virtual desktops'. 

It defines these as desktops 'of which only one can be shown on the screen at 
a time', and indeed there is a _net_current_desktop property defined to point
at the currently shown desktop.

Notion, however, when used with mod_xinerama, has a different model: we have 
several WScreen's, all of which are visible at the same time. Each WScreen may
contain a collection of workspaces (WGroupWS). Per WScreen, one workspaces is
actually shown.

Obviously, these models don't quite match. Any ideas how we should marry these
2 worlds? 

On the one hand it seems neat to have each WGroupWS get a EMWH DESKTOP, but of
course then you have as many 'current' desktops as there are WScreen's. We 
could switch the _NET_CURRENT_DESKTOP whenever the user switches the mouse to
the other WScreen. That doesn't really seem like the way this was intended, 
but it's the least invalid interpretation I can think of.

Ideas?


Kind regards,

Arnout
