Re: G_LIST_REMOVE not working... at least not for me :-)

[Mike Dailey <daileyml yahoo com>]

No, that doesn't appear to work.

I get an error stating that I can not GTK_LIST_CLEAR a
G_LIST.

Here is my error:

(FMC:2376): GLib-GObject-WARNING **: invalid cast from
(NULL) pointer to `GtkList'

(FMC:2376): Gtk-CRITICAL **: file gtklist.c: line 1139
(gtk_list_clear_items): assertion `GTK_IS_LIST (list)'
failed


There is no G_LIST_CLEAR_ITEMS equivelent, and my list
is a G_LIST, not a GTK_LIST.... so at this point I'm
pretty much lost.  There seems to be no API reference
or command explaining how--when you remove the last
item from a G_LIST--you are about to update the parent
Combo box to show the now empty (NULL) list.  Since
you can't 'gtk_combo_set_popdown_strings' a NULL list,
I have no idea what the GTK developers do to resolve
this.

Thoroughly confused...
