From 04bda8ad1e0cb676d711dbf0f22ff9f4fb615891 Mon Sep 17 00:00:00 2001 From: Damon Chaplin Date: Tue, 23 Oct 2001 00:23:42 +0000 Subject: added setDefaultTimezone() method. 2001-10-22 Damon Chaplin * idl/evolution-calendar.idl: added setDefaultTimezone() method. * pcs/cal-backend.c (cal_backend_get_default_timezone): (cal_backend_set_default_timezone): new functions to call class methods. * pcs/cal-backend-file.c: lots of changes to handle the default timezone and use it. * pcs/query.c: use the default timezone. * gui/dialogs/task-details-page.c (date_changed_cb): initialized completed_tt. * gui/dialogs/event-page.c: changed it to handle DATE values. The 'All Day Event' checkbox is only set now when the DTSTART and DTEND are DATE values. * gui/dialogs/comp-editor-util.c (comp_editor_free_dates): free the CalComponentDateTime structs as well. * gui/e-tasks.c: set the default timezone on the server. * gui/tag-calendar.c: * gui/gnome-cal.c: * gui/e-week-view.c: * gui/e-day-view.c: updates to handle DATE values. * gui/e-calendar-table.c (date_compare_cb): updated to use the new ECellDateEditValue values, so it now works. (percent_compare_cb): updated to use GPOINTER_TO_INT values. (e_calendar_table_init): use an ECellPercent for the percent field and an ECellDateEditText for the date fields. * gui/comp-util.c (cal_comp_util_compare_event_timezones): return TRUE if the DTSTART or DTEND is a DATE value. We don't want to show the timezone icons for DATE values. * gui/comp-editor-factory.c (resolve_pending_requests): set the default timezone on the server. * gui/calendar-model.c: major changes to support sorting properly. For date and percent fields we now use subclasses of ECellText, so we don't use a char* as the model value. For the percent field we now use a GINT_TO_POINTER. For the date fields we now use a ECellDateEditValue* as the value. * gui/calendar-config.c (calendar_config_configure_e_cell_date_edit): set the timezone and use_24_hour flags of the new ECellDateEditText. * conduits/todo/todo-conduit.c (pre_sync): * conduits/calendar/calendar-conduit.c (pre_sync): set the default timezone on the server. * cal-util/timeutil.c (time_days_in_month): removed debug message. * cal-util/test-recur.c: try to handle timezones in the iCalendar file properly, and updated to pass default timezone. * cal-util/cal-util.c (cal_util_generate_alarms_for_comp): (cal_util_generate_alarms_for_list): added default timezone argument. * cal-util/cal-recur.c: changed many of the functions to take a default timezone, to use to resolve DATE and floating DATE-TIME values. * cal-client/cal-client.c (cal_client_set_default_timezone): new function to set the default timezone. (cal_client_ensure_timezone_on_server): new function to ensure that a given timezone is on the server. * gui/e-cell-date-edit-text.c: new subclass of ECellText to display and edit a date value. * cal-util/cal-recur.c (cal_obj_byday_expand_monthly): changed week_num to -week_num when calculating the weeks to go back from the end of the month for things like BYDAY=-2WE. Fixes bug #11525. (cal_recur_generate_instances_of_rule): only go up to MAX_YEAR (2037). We can't really handle anything past that anyway. (cal_recur_ensure_rule_end_date): initialize cb_date.end_date to 0, so if the RULE doesn't generate COUNT instances we save 0 as the time_t. svn path=/trunk/; revision=13920 --- calendar/gui/e-cell-date-edit-text.c | 234 +++++++++++++++++++++++++++++++++++ 1 file changed, 234 insertions(+) create mode 100644 calendar/gui/e-cell-date-edit-text.c (limited to 'calendar/gui/e-cell-date-edit-text.c') diff --git a/calendar/gui/e-cell-date-edit-text.c b/calendar/gui/e-cell-date-edit-text.c new file mode 100644 index 0000000000..d0b9d2bf7a --- /dev/null +++ b/calendar/gui/e-cell-date-edit-text.c @@ -0,0 +1,234 @@ +/* -*- Mode: C; tab-width: 8; indent-tabs-mode: t; c-basic-offset: 8 -*- */ + +/* + * Author : + * Damon Chaplin + * + * Copyright 2001, Ximian, Inc. + * + * 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.
