The idea is to have a small module that would be just another layer above Gtk , that would settle a few 
things automatically :
when you create a window -> automatically add a signal_connect("delete_event",\&ByeBye);
when you create a CList ->automatically add a signal_connect("select_row",sub{"increment the log of the 
widget";}); 
when you create a Combo ->automatically add a $combo->entry(signal_connect("activate",sub{"increment the log 
of the widget";});
etc...
This way , it's easy in the script , for instance , to set what the popdown strings of a combo must be ... To 
have the last selection in a clist , you just lookup in its log .

What you indicated , putting data in the widget is fine ( thanks for that ) , but i still need extra space 
for some data that's beyond the scope a single widget . Must i create a global or can i use one of GTk's ( if 
there's any ) ?

It did , thanks . But what is this nowhere to be found , even in the C documentation ?

I know this tutorial , it's my bible : always open in one of my virtual desktops ...
But about Gnome ?

I'll try this . 

Thanks.
