All right, I just post somewhere else than pansko thread
It's simple, I want to recompile Xfmedia in order to substitute the Rat logo with something more
like Slitaz present icon theme .
It's not just a question of changing the icon in /usr/share/pixmaps but also the one in dispalyed onto openbox window and lxpanel.
I see in the Xfmedia sources the Rat logo in a folder , so I suppose that this logo is duplicated and hard-coded in the program it self as I cannot reach it in my filesystem
For exemple, these icons exists for Firefox /usr/lib/firefox/chrome/icons/default
