they are just examples

the fact is that i've started working with gtk two days ago because i
was interested in make a gnome panel monitor, and in the tutorial i've
found, i create a panel with the bonobo inititialization..
i dont know if i can do this even with glade..
Talking about the spawn, i think the problem is due to the command
itself (uname) that at the end print a "\n"; So i gotta throw away that
char from the string to obtaine a one line label, isn't it?
