Bug 547270 – Make GtkHSV public
* gtk/Makefile.am
* gtk/gtk.h: install gtkhsv.h as public header (its symbols were
always public anyway).
* gtk/gtkhsv.h: add single-include guards, add class struct padding,
seal the instance member, cleanup.
* gtk/gtkhsv.c: center the widget in its allocation,
add "Since: 2.14", cleanup.

* Practically everything changed.
Change all references of GIMP Toolkit (and variations of it)
to GTK+ Toolkit, showing no mercy at all to our beloved
ancestry. (#540529)
svn path=/trunk/; revision=20709
2008-05-28 Michael Natterer <mitch@imendio.com>
* gtk/gtk.h: define __GTK_H_INSIDE__ around including all other
headers.
* gtk/gtktypebuiltins.h.template
* gtk/gtkversion.h.in
* gtk/gtk*.h: add single-include guards that #error out if
GTK_DISABLE_SINGLE_INCLUDES is defined and any of these files is
included individually.
* gtk/gtkprintbackend.h
* gtk/gtkprinter-private.h
* gtk/gtktextlayout.h
* gtk/gtktexttagprivate.h
* gtk/gtktexttypes.h
* gtk/gtktreedatalist.h: include <gtk/gtk.h> instead of individual
headers in these private or semi-private headers.
* gtk/gtkimmodule.h: also here because it's not in gtk.h.
* gtk/gtkpagesetupunixdialog.h
* gtk/gtkprinter.h
* gtk/gtkprintjob.h
* gtk/gtkprintunixdialog.h: likewise in the gtkunixprint headers.
* gtk/gtkclist.h
* gtk/gtkcombo.h
* gtk/gtkctree.h
* gtk/gtkfilesel.h
* gtk/gtkitemfactory.h
* gtk/gtklist.h
* gtk/gtklistitem.h
* gtk/gtkoldeditable.h
* gtk/gtkoptionmenu.h
* gtk/gtkpixmap.h
* gtk/gtkpreview.h
* gtk/gtksignal.h
* gtk/gtktipsquery.h: whenever possible, include only <gtk/gtk.h>
instead of individual headers in these deprecated headers. They
don't get included at all when GTK_DISABLE_DEPRECATED is defined,
so if an app needs them anyway, it must undef GTK_DISABLE_DEPRECATED
and include them individually, which should continue to work.
* gtk/gtkclist.c: include "gtkctree.h" because of the change
above.
svn path=/trunk/; revision=20221
2008-05-02 Michael Natterer <mitch@imendio.com>
* gtk/gtk.h: add 15 files that were missing (they all got included
indirectly by including gtk.h, so should have been here in the
first place).

Make GtkCellView public, since people seem to have uses for it,

gtk_accel_group_add/remove, gtk_accel_group_handle_add/remove,
gtk_accel_group_create_add/remove, gtk_accel_group_entries_from_object.
introduced ::accel_changed signal for change notification, and
gtk_accel_group_connect/disconnect to connect closures to accel groups.
made gtk_accel_group_attach/detach and gtk_accel_group_activate private
functions.
deprecated gtk_accel_group_ref/unref.
* gtk/gtkaccellabel.[hc]: changes to make accellabels pay attention
to accel group changed notification and basically operate on closures.
removed gtk_accel_label_get_accel_object and
gtk_accel_label_set_accel_object.

gtk_accel_label_set_accel_widget.

of accelerators on menu items that don't come with an accelerator
binding by default.

them appropriately in the parser.

gtk_widget_accelerators_locked, gtk_widget_remove_accelerators and
gtk_widget_(un)lock_accelerators.
accelerators maintained through gtk_widget_add/remove_accelerator()
are not runtime changable now, the correct sequence to setup a
widget for runtime changable accelerators is now:
gtk_accel_map_add_entry(accel_path, key, mods);
_gtk_widget_set_accel_path(widget, accel_path, accel_group);
* gtk/gtkwindow.[hc]: accelerator changes, proxy and coalesce accel
group changes (as well as mnemonic changes) through the new signal
::accels_changed.
Sat Nov 10 12:08:56 2001 Tim Janik <timj@gtk.org>
