I tried your example because I don't know the _NET_WM_PID property and was interested in it. Unfortunately the call to XGetWindowProperty() never filled the &prop data. Your code is checking against the return code of XGetWindowProperty() which is fine but prop equals to (nil) in all my tests. I was using metacity as suggested windowmanger. Do you have any idea why it fails ? The window Id which is required of course is obtained from a "xwininfo" call. I passed the information from this command to the example. Did I something stupid ?
