gtkradiobutton property group

[John Williams <asb1231 gmail com>]

Hello,

I'm looking at the GtkRadioButton
(http://library.gnome.org/devel/gtk/stable/GtkRadioButton.html) and
see that the property group is of type GtkRadioButton *, but the
return of the function gtk_radio_button_get_group is a GSList *. Is
this right?

I suppose that the in the group property have all the other radio
buttons of the same group, is this right?

Thank you!
