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
