yes, i have seen that, but it's my co-worker who have begun the project 
and included clists, and it seems to be enough for me at the moment


so, about the depreciated state of Clist :
is there a protocol to follow, to convert Clist in Tree_View,
but avoiding to fall in a state where all goes wrong because of my 
unknown of Tree_View mechanisms ?

It's right that if there was a way to easily upgrate to Tree_View, i 
would be happy to use its advantages :-)


about the "clicked" signal : (in fact it's not Clist-specific)
i didn't see any equivalent in Tree_View, rather than in Clist.
Yet i use "button_press_event", and it's functional even if it's less 
ergonomic than a "real click"

but, why not set the "clicked" signal for all widgets, as there is 
"button_press_event" and some others, rather than only for buttons, 
Tree_View, and some other widgets ???
