33 * @Short_description: Displays a calendar and allows the user to select a date
36 * #GtkCalendar is a widget that displays a Gregorian calendar, one month
37 * at a time. It can be created with gtk_calendar_new().
39 * The month and year currently displayed can be altered with
40 * gtk_calendar_select_month(). The exact day can be selected from the
41 * displayed month using gtk_calendar_select_day().
43 * To place a visual marker on a particular day, use gtk_calendar_mark_day()
44 * and to remove the marker, gtk_calendar_unmark_day(). Alternative, all
45 * marks can be cleared with gtk_calendar_clear_marks().
47 * The way in which the calendar itself is displayed can be altered using
48 * gtk_calendar_set_display_options().
50 * The selected date can be retrieved from a #GtkCalendar using
51 * gtk_calendar_get_date().
53 * Users should be aware that, although the Gregorian calendar is the legal
54 * calendar in most countries, it was adopted progressively between 1582 and
55 * 1929. Display before these dates is likely to be historically incorrect.
