Retrieve Ubuntu launcher icon

问题:

Is there a way to retrieve application launcher icon.

I tried xprop _NET_WM_ICON command but it returns with

_NET_WM_ICON: Not found error. 

But I can see the icon in System Tray(Launcher).

How can we retrieve that icon. Any other method ?

In Ubuntu/Unity it's defined in application .desktop file, not _NET_WM_ICON. See my related answer and desktop file specification

You can associate your window with desktop file by setting _NET_WM_DESKTOP_FILE property
