Does anyone know how to get a window icon by PID in Linux? Me interest only examples on C++ with Xlib or on Java with JNA.
PS. Excuse me for my English.

6PIDs don't have window icons, and one process (e.g. pid) may have multiple windows, or none at all - Linux is not a natively graphical system. There will be plenty of PIDs that have absolutely nothing to do with the Xwindow system and have no windows, period. – Marc B Aug 03 '12 at 19:10

2Yes, I understand it. And I precisely know that necessary process has a one or more windows. – Sworfly Aug 03 '12 at 19:21

1I think what Marc wanted to express was that if PID's aren't necessarily associated with any particular window there probably won't be any standard way to obtain a window icon from a PID. – Cubic Aug 03 '12 at 19:42

You could use GTK, loop through open windows, check their PID and grab the icon from the window:
