From 4517358debc8bcd761a469e901bae160704deaf2 Mon Sep 17 00:00:00 2001 From: Damon Chaplin Date: Thu, 14 Jun 2001 06:00:21 +0000 Subject: new dialog for setting the time zone. 2001-06-14 Damon Chaplin * gui/dialogs/e-timezone-dialog.[hc]: * gui/dialogs/e-timezone-dialog.glade: new dialog for setting the time zone. * gui/dialogs/Makefile.am: added timezone dialog files. * idl/evolution-calendar.idl: added CalTimezoneInfo struct and seq, and getBuiltinTimezoneInfo method. * pcs/cal.c (impl_Cal_get_builtin_timezone_info): implemented method. (cal_class_init): added method to epv. * cal-client/cal-client.c (struct CalClientPrivate): added timezone_info array to contain cached info on builtin timezone city names and coordinates. (cal_client_get_builtin_timezone_info): new function to get the info about builtin timezones. * cal-client/cal-client.h: added CalTimezoneInfo struct, to contain the city names and coords of the builtin timezones. svn path=/trunk/; revision=10223 --- calendar/gui/dialogs/Makefile.am | 3 + calendar/gui/dialogs/e-timezone-dialog.c | 526 +++++++++++++++++++++++++++ calendar/gui/dialogs/e-timezone-dialog.glade | 264 ++++++++++++++ calendar/gui/dialogs/e-timezone-dialog.h | 72 ++++ 4 files changed, 865 insertions(+) create mode 100644 calendar/gui/dialogs/e-timezone-dialog.c create mode 100644 calendar/gui/dialogs/e-timezone-dialog.glade create mode 100644 calendar/gui/dialogs/e-timezone-dialog.h (limited to 'calendar/gui/dialogs') diff --git a/calendar/gui/dialogs/Makefile.am b/calendar/gui/dialogs/Makefile.am index 74c65d72ab..de97ea2d45 100644 --- a/calendar/gui/dialogs/Makefile.am +++ b/calendar/gui/dialogs/Makefile.am @@ -32,6 +32,8 @@ libcal_dialogs_a_SOURCES = \ comp-editor-util.h \ delete-comp.c \ delete-comp.h \ + e-timezone-dialog.c \ + e-timezone-dialog.h \ event-editor.c \ event-editor.h \ event-page.c \ @@ -51,6 +53,7 @@ glade_DATA = \ alarm-notify.glade \ alarm-page.glade \ cal-prefs-dialog.glade \ + e-timezone-dialog.glade \ event-page.glade \ recurrence-page.glade \ task-details-page.glade \ diff --git a/calendar/gui/dialogs/e-timezone-dialog.c b/calendar/gui/dialogs/e-timezone-dialog.c new file mode 100644 index 0000000000..7e9fce6cb8 --- /dev/null +++ b/calendar/gui/dialogs/e-timezone-dialog.c @@ -0,0 +1,526 @@ +/* -*- Mode: C; tab-width: 8; indent-tabs-mode: t; c-basic-offset: 8 -*- */ +/* Evolution calendar - Timezone selector dialog + * + * Copyright (C) 2001 Ximian, Inc. + * + * Authors: Damon Chaplin + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License as published by + * the Free Software Foundation; either version 2 of the License, or + * (at your option) any later version. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
