Detect Desktop Environment

[bitChanger]

I don't know how much help this will be to you, but I always perform the following commands from a terminal.

ps -ef | grep startkde
 
or
 
ps -ef | grep gnome-session

ps -ef | grep startkde

or

ps -ef | grep gnome-session

To copy to clipboard, switch view to plain text mode 

startkde (to run kde)
gnome-session (to run Gnome)

This will tell you whether kde or gnome is running. You could write code to perform this system call and then parse the return to determine the environment.

Not pretty, but it just might work.

If you want to see how Qt does it, take a look at qt_init() in src/gui/kernel/qapplication_x11.cpp. Search for "X11->desktopEnvironment".
