My problem remains the same.
I try to feed a GClist Widget (DirList in the code), in the
OpenDskFile function. It avoid a global declaration, I try to use
g_object_set_data() function. The interface is like, it did not link
the DirList widget to the main widget pWindow (in my code).

To prevent to bored you, to you know a good tutorial to learn the
interface production ?
