sorry, accidently hit submit,
was trying to say that the link changed to
http://api.kde.org/4.x-api/kde-workspace-apidocs/libs/kworkspace/html/namespaceKWorkSpace.html

(no base in kdebase anymore)

thanks for the KDE_SESSION_VERSION info.
i’ve made a post here: http://dazzle.cs.mcgill.ca/wordpress/?p=11 which references your blog.
(i’m trying to document things i find useful, such as how you’ve done above)
thanks again!

James: I looked at the source but it ended up being available at the documentation for KWorkspace IIRC. Of course how you go from session management to KWorkspace is kind of strange to me but eh, whatever.

I have no clue how to detect if you’re running under a GNOME session but KDE_FULL_SESSION is the way to detect KDE. Note that it’s only been implemented since 3.5.5 so as long as you don’t need to detect older KDE sessions that should be fine.

If you need to separate between KDE 3.5 and KDE 4 you can use the KDE_SESSION_VERSION variable added in KDE 4.

Please see kdebase/workspace/startkde.cmake for more information (or just vim `which startkde` if you have KDE installed). grep for KDE_FULL_SESSION.

many thanks, i’ve been trying to find documentation on those three int’s too. funny that i should find it here, and not on a kde website. oh well. in case it’s useful to you, here are the docs for the gnome version (not to incite DE wars, but because i was looking for them too)
http://www.gnome.org/~mccann/gnome-session/docs/gnome-session.html#org.gnome.SessionManager.Logout

ps: did you get your answer from the source, or is there some magical documentation somewhere else?

pps: in case you happen to know and don’t mind being asked, what is the *correct* way to detect which desktop environment is running. at the moment i have something that looks like (python):

def session():
# this was adapted from:
# http://gitweb.compiz-fusion.org/?p=fusion/misc/compiz-manager;a=blob;f=compiz-manager
# TODO: is there a better way to implement this ?
if os.name == ‘nt’: return ‘windows’
elif os.getenv(‘KDE_FULL_SESSION’) == ‘true’: return ‘kde’
elif os.getenv(‘GNOME_DESKTOP_SESSION_ID’) != ”: return ‘gnome’
else: return ”

cheers!

Thanks! I’ve always wondered how to do that.
