RE: [gtk-list] Re: gtk_clist_set_sort_column (?)

["Olivier Nenert" <onenert condumex com mx>]

the sort_column you may specify is mainly useful for the default_sort
provided by the
same gtk_clist. if you want to provide your own (like *MyStrcmp*),
then you can also check the list->row_column inside your code and it's not
a bad idea...
now if your MyStrcmp is actually a strcmp.. just use the default sort as it
does exactly
what you want... if your MyStrcmp compare strings a different way,
say you have
gint MyStrcmp(gchar *t1, gchar *t2)
{
    g_return_val_if_fail(t1, 0);
    g_return_val_if_fail(t2, 0);

    return(atoi(t2)-atoi(t1));
}
(for instance)

then you'd do something like this :
     gtk_clist_set_compare_func(GTK_CLIST(main_clist),
     (GtkCListCompareFunc)MyStrcmpSort);

and have:

static gint MyStrcmpSort(GtkCList      *list,
         GtkCListRow *row1,
         GtkCListRow *row2)
{
     /* ok it's not too clean, ou should check if the cell is text or
pixtext and potentially use
        GTK_CELL_PICTEXT(blahblah)->text, but you got the idea)  */
    return(MyStrcmp(GTK_CELL_TEXT(row1->cell[list->sort_column])->text,
    GTK_CELL_TEXT(row2->cell[list->sort_column])->text));
}

good luck...

Olivier.
