Wed Oct 10 12:48:38 2001 Owen Taylor <otaylor@redhat.com> * gtk/gtkmain.c (gtk_init_check): Call setlocale (LC_ALL, ""). (#60606) * gtk/gtkmain.c (gtk_disable_setlocale): Add function to disable calling setlocale (LC_ALL, ""). * gtk/gtkmain.c (gtk_set_locale): Indicate in the docs that this function is not typically useful. * gdk/x11/{gdkim-x11.c,gdkmain-x11.c,gdkprivate-x11.h}: Automatically initialize GDK for the current locale on gdk_init(). Don't reset locale to C when XSupportsLocale() fails. * gdk/linux-fb/gdkim-fb.c (gdk_set_locale): Remove useless checks for UTF-8 locale breakage that mattered only for X. * examples/calendar/calendar.c tests/{testgtk.c,testtext.c,testcalendar.c}: Remove calls to gtk_set_locale(). * gtk/gtkiconfactory.c gtk/gtkitemfactory.c: gdk_pixbuf_new_from_stream => gdk_pixbuf_new_from_inline.
