Wed Mar 7 13:24:57 2001 Tim Janik <timj@gtk.org> * gtk/*.c: marshaller fixes. * gtk/gtkmarshal.list: extreme cleanup. * gtk/gtktreeview.c (gtk_tree_view_class_init): disable interface param spec for now. * gtk/gtktexttag.c (gtk_text_tag_set_property): use g_value_get_boxed() where appliable. * gtk/gtktypeutils.[hc]: updates to GLib API changes. special cased autogenerated boxed types from gtktypebuiltins_ids.c which are not reference counted: GtkSelectionData, GdkEvent, GdkColor, GtkTextIter, PangoTabArray, PangoFontDescription, GtkTreeIter and GtkTreePath. Thu Mar 1 03:58:56 2001 Tim Janik <timj@gtk.org> * gtk/gtktreeselection.h: * gtk/gtktreemodel.c: * gtk/gtktreedatalist.[hc]: fixed includes. no gobject/* file should be included directly, and gobject/gmarshal.h as well as gtk/gtkmarshal.h even can't be included directly. * Makefile.am: grr, install gtk-config-2.0. * gtk/testgtk.c: * gtk/simple.c: * gtk/gtkmenu.c: * gtk/gtkitemfactory.c: use g_object_connect() instead of passing "*signal*::*" args to gtk_widget_set(). * gtk/gtktypeutils.[hc]: got rid of GTK_TYPE_SIGNAL. * gtk/*.c: removed trailer arg from property setters and getters. macro fixups. Thu Mar 1 04:01:57 2001 Tim Janik <timj@gtk.org> * test-gdk-pixbuf.c: fixed includes.
