NOTE: I'm assuming you're talking about a GtkCList.  If not, ignore the
rest of this message.

You'd think such a function would exist, but when I needed the same
thing, I couldn't find one.  I did the following:

void clist_select_row_callback(GtkWidget* clist, gint row, gint column,
                    GdkEventButton* event, gpointer data)
{
...
    /* there is no "get current selection" function for the clist.
       the OK button needs to know the current selection, add it
       as user data to the clist */
    gtk_object_set_user_data(GTK_OBJECT(clist), (gpointer)row);
...
}

and when I needed the row number:

    row = (gint)gtk_object_get_user_data(GTK_OBJECT(data));

I'd love to know if there was a better way to handle this!
