Window frame icon

[jf at dockes.org]

Hi,

Is there somewhere a description of how the window manager finds the small
icon which is displayed in the left of the top of the window frame ? Also
besides the window title in the panel area when iconified.

I have an application (recoll) for which the icon is ok in the application
menu, but which only gets a generic icon for the running program, so I
guess that something is missing somewhere and it would be great if someone
knew what...

Cheers,

jf
