Editing GtkList Labels

[Keith Geffert <keith penguingurus com>]

Hello all,

After reading through the api and the mailing list I just couldn't figure
it out.

Is it possible to edit the label associated with a GtkListItem?  As in, after
getting the selection with 
sel = GTK_LIST(list)->selection;
selitem = GTK_LIST_ITEM(sel->data);

now knowing the ref to the listitem is there a way to change the associated
label?  If there isn't a direct way what's the current convention for doing
this?

Thanks,

Keith
