# Gtk::Calendar Class Reference
[Widgets]

Inheritance diagram for Gtk::Calendar:

[legend]

List of all members.

## Detailed Description

Display a calendar and/or allow the user to select a date.

This is a widget that displays a calendar, one month at a time.

The month and year currently displayed can be altered with select_month(). The exact day can be selected from the displayed month using select_day().

The way in which the calendar itself is displayed can be altered using set_display_options().

The selected date can be retrieved from a GtkCalendar using get_date().

If performing many 'mark' operations, the calendar can be frozen to prevent flicker, using freeze(), and 'thawed' again using thaw().

The Calendar widget looks like this:

## Member Typedef Documentation

typedef sigc::slot<Glib::ustring, guint, guint, guint> Gtk::Calendar::SlotDetails

For instance,.

     Glib::ustring on_calendar_details(guint year, guint month, guint day);

Parameters:
