* gtk/gtkwidget.c (gtk_widget_get_property): fix PROP_EVENTS.
* gtk/Makefile.am:
* gtk/gtk.h: disabled GtkPacker compilation.
* gtk/gtkarg.[hc], gtk/gtkargcollector.c: got rid of these.
* gtk/gtknotebook.c:
* gtk/gtktable.c:
* gtk/gtkbox.c: ported this over to child properties.
* gtk/gtksettings.c: fetch class properties via
g_object_class_list_properties().
* gtk/gtkcontainer.[hc]: implemented child properties, got rid of the
child arg interface. use gobjectnotifyqueue.c for child property
notification.
* gtk/gtkwidget.[hc]: provide necessary means for container child
properties, i.e. ::child_notify signal,
gtk_widget_freeze_child_notify(),
gtk_widget_child_notify(),
gtk_widget_thaw_child_notify().
* tests/testgtk.c: removed inferior property handling code, for
property editing, a generic module should be used, and GLE
coincidentally fullfills that purpose.
* docs/reference/Makefile.am: disabled gtk docs building, gtk-doc
needs to be adapted to g_object_class_list_properties() before this
builds again.
