gtk/gdk/gdkpixmap.c
Tim Janik d69496c060 urg, removed implementation of gtk_marshal_VOID__INT_INT_INT_INT. if 
Wed Oct 25 20:47:41 2000  Tim Janik  <timj@gtk.org>

        * gtk/gdk-pixbuf-loader.c (gdk_pixbuf_loader_class_init): urg, removed
        implementation of gtk_marshal_VOID__INT_INT_INT_INT. if people do that,
        couldn't they at least give it a non-standard name?

        * gtk/gtktextlayout.c: arg! yet another implementation of
        gtk_marshal_VOID__INT_INT_INT_INT(), is this a conspiracy?

        * gtk/gtktextbuffer.c: gotcha! captured a vagabonding
        gtk_marshal_VOID__INT_POINTER_INT() implementation, braught it back
        home. now i know this _is_ a conspiracy.

        * gtk/gtkwidget.c (gtk_widget_class_init): marshaller fixups for
        ::state-changed.

        * gtk/gtkaccelgroup.c (gtk_accel_group_create_remove):
        (gtk_accel_group_create_add): marshaller signature fixups.

        * gtk/gtklistitem.c (gtk_list_item_class_init): signal creation fixups,
        pass in GTK_TYPE_SCROLL_TYPE instead of GTK_TYPE_ENUM.

        * gtk/gtkobject.[hc]: removed GTK_CONNECTED flag, it's not valid
        anymore.

Tue Oct 24 23:59:21 2000  Tim Janik  <timj@gtk.org>

        * docs/reference/Makefile.am: disabled SUBDIRS for the moment, since
        due to the signal system changes, it wouldn't build currently. to
        be fixed soon.

        * docs/Changes-2.0.txt: GtkSignal/GSignal updates.

        * gtk/gtkwidget.c: ::direction_changed takes an enum as argument,
        so it needs gtk_marshal_VOID__ENUM() instead of
        gtk_marshal_NONE__UINT().

        * gdk/gdk*.c: adapted type registration functions.

        * gtk/gtkbindings.c:
        * gtk/gtkaccelgroup.c: operate on GSignalQuery, GtkSignalQuery is
        gone.

        * gtk/gtkenums.h: define GtkSignalRunType in terms of GSignalType.

        * gtk/gtkobject.c:
        (gtk_object_destroy):
        (gtk_object_shutdown): fixed recursion guards. basically we have to
        catch the case where any of GObject.shutdown() or gtk_object_destroy()
        is called during ::destroy, and avoid recursion there.

        * gtk/gtktypeutils.c:
        * gtk/maketypes.awk: awk-script hackup to provide gtk_type_init() with
        boxed_copy/boxed_free. this needs a more general solution based on a
        publically installed code-generator utility.

        * gtk/gtktypeutils.[hc]: compat aliased GTK_TYPE_BOXED to G_TYPE_BOXED,
        glib's gobject has support for that now.
        define GtkSignalMarshaller in terms of GSignalCMarshaller.


Mon Oct 23 09:36:42 2000  Tim Janik  <timj@gtk.org>

        * gtk/gtksignal.[hc]:
        * gtk/gtkmarshal.[hc]:
        * gtk/Makefile.am: generate marshallers with glib-genmarshal and don't
        compile gtkmarshal.c on its own anymore, just include it in gtksignal.c.
        removed #include <gtkmarshal.h>s all over the place, gtksignal.h takes
        care of that.

        * *.c: marshaller name fixups.

        * gtk/gtkmarshal.list: added a comment briefing the format.

Sun Oct 22 23:14:39 2000  Tim Janik  <timj@gtk.org>

        * gtk/gtksignal.[hc]: nuked old implementation. we mostly have
        compatibility macros here now. more specifically, most of
        the API is preserved (yes, _most_, nonwithstanding the
        following exceptions listed, the API is stil lHUGE ;)
        things that got removed completely:
        GtkSignalQuery, gtk_signal_query(), gtk_signal_n_emissions(),
        gtk_signal_n_emissions_by_name(), gtk_signal_handlers_destroy(),
        gtk_signal_set_funcs(), gtk_signal_handler_pending_by_id(),
        gtk_signal_add_emission_hook(), gtk_signal_add_emission_hook_full(),
        gtk_signal_remove_emission_hook().
        non-functional functions variants:
        gtk_signal_add_emission_hook(), gtk_signal_remove_emission_hook().
        the GtkCallbackMarshal argument to gtk_signal_connect_full() is
        not supported anymore.
        (gtk_signal_compat_matched): new internal function to aid
        implementation of the compatibility macros, it  provides
        functionality to block/unblock/disconnect handlers based
        on func/data.

        * gtk/gtkenums.h: define GtkSignalRunType in terms of GSignalType,

        * *.c: adaptions to new type registration API signatures.


Fri Oct 20 15:26:33 2000  Tim Janik  <timj@gtk.org>

        * gtk/gtktypeutils.[hc]: removed G_TYPE_GTK_POINTER cludge.
