how to make radio buttons without default selected? and, how to force all de-selected?

[Ben Johnson <ben@xxxxxxxxx>]

Hi.  My name is Ben Johnson.   This is my first time posting, and I'm
pretty much a Gtk newbie.

I've successfully created a set of radio buttons that look and act a lot
like a set of related toggle buttons.  Now I want them to behave *more*
like toggle buttons.  The problem is, there is always at least one of
the buttons selected.  I want the set to start out with no default
selected, and I want to be able to de-select a button without having a
new one get activated.

so far all I've tried is using gtk_toggle_button_set_active() on each of
the buttons while I create them, and that doesn't work.  Do I need to
call that function later?  like after they've been displayed?  or, is
there a different method/function I need to use?  My strategy for
allowing de-selection is running this same function in the "clicked"
signal handler.  I haven't tried it yet because I'm guessing it won't
work.

Thanks for your help.

/* this doesn't work like I hoped */
{
  static GtkWidget * last_created = NULL;

  if( ! last_created )
    widget = gtk_radio_button_new_with_label(NULL, name);
  else
    widget = gtk_radio_button_new_with_label_from_widget(
                 GTK_RADIO_BUTTON(last_created), name);

  /* draw like a regular toggle button */
  gtk_toggle_button_set_mode (GTK_TOGGLE_BUTTON(widget), FALSE);
  /* no default selected */
  gtk_toggle_button_set_active (GTK_TOGGLE_BUTTON(widget), FALSE);
}
