Yes, as far as I know there is no clean way to get the items selected. Here 
is what I'm doing:


GList            *selected;
    
selected = GTK_CLIST(receiver_clist)->selection;
while (selected != NULL)
{
     gtk_clist_get_text(GTK_CLIST(clist), GPOINTER_TO_INT(selected->data), 0, 
                              &data);

/*  do whatever you need to with data */

     selected = selected->next;
}

Sorry, my example is for a CList but the idea is the same for a list, you 
just cycle through the linked list grabbing the data until you hit NULL. 

Use at your own risk I suppose since you are messing around with an internal 
data structure, but it's the only sane way I have found to do it.
