WM_CLIENT_LEADER(WINDOW): window id # 0x3200001
 
'''_NET_WM_PID(CARDINAL) = 7661'''
 
WM_LOCALE_NAME(STRING) = "en_US.UTF-8"
 
WM_CLIENT_MACHINE(STRING) = "tweedleburg"
 
WM_NORMAL_HINTS(WM_SIZE_HINTS):
 
                program specified minimum size: 0 by 0
 
                window gravity: NorthWest
 
WM_PROTOCOLS(ATOM): protocols  WM_DELETE_WINDOW, WM_TAKE_FOCUS, _NET_WM_PING, _NET_WM_SYNC_REQUEST
 
'''WM_CLASS(STRING) = "Navigator", "Firefox"'''
 
[...]
 
From this you can tell that the application identifies itself as "Navigator", "Firefox". If this is too unsure for you, have a look at the process ID PID, which is 7661 in the above example:
 
ps -A |grep 7661
 
  7661 ?        01:00:53 firefox-bin
 
By this you see that the [[process]] that manages the Window is number 7661 and called firefox-bin.
