It isn't clear what value DirList has here, but let's suppose
it's OK.

Please do not use GtkCList, use GtkTreeView.  Any tutorial
that taught you to use GtkClist now in 2006 should go to
the stamping mill.

The callback function definitely should not be NULL.

Please convert the code to use GtkTreeView.

GtkTreeView supports scrolling natively (don't know about
GtkCList), so gtk_container_add(scrolled_window, treeview);
should suffice.
