remove left-over usages of an anonymous GBoxed typedef.
Mon Jun 11 17:07:06 2001 Tim Janik <timj@gtk.org> * gboxed.[hc]: remove left-over usages of an anonymous GBoxed typedef. * gobjectnotifyqueue.c: moved property notify queue implementation bits into this function. * gparam.[hc]: added g_param_spec_pool_belongings(), completed g_param_spec_pool_list(). added GParameter for _setv() functions. * gobject.[hc]: use gobjectnotifyqueue.h implementation now. got rid of properties_changed signal. new functions g_object_newv(), g_object_class_list_properties(). removed "properties_changed" signal. * gtype.[hc]: added g_type_depth() to figure number of parent types + 1 for a type. * gsignal.h: add g_signal_connect() (as per owen's request) and g_signal_connect_swapped().
