What process a window belongs to?

Por: rcmorano Tags:
Windows managers add some properties to windows and one of them is '_NET_WM_PID(CARDINAL)' which stores what PID created that window. In order to get that PID, we just have to execute the command below and click on the window we want to read info from :] 
$ xprop |grep WM_PID
_NET_WM_PID(CARDINAL) = 2717
$ ps ax | grep firefox
2717 ?        Sl   387:39 /usr/lib/firefox-3.0.6/firefox
