Description

GtkCalendar is a widget that displays a calendar, one month at a time. It can be created with gtk_calendar_new().

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

To place a visual marker on a particular day, use gtk_calendar_mark_day() and to remove the marker, gtk_calendar_unmark_day(). Alternative, all marks can be cleared with gtk_calendar_clear_marks().

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

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

Details

GtkCalendar

typedef struct _GtkCalendar GtkCalendar;

num_marked_dates is an integer containing the number of days that have a mark over them.

marked_date is an array containing the day numbers that currently have a mark over them.

month, year, and selected_day contain the currently visible month, year, and selected day respectively.

All of these fields should be considered read only, and everything in this struct should only be modified using the functions provided below.

Note

Note that month is zero-based (i.e it allowed values are 0-11) while selected_day is one-based (i.e. allowed values are 1-31).

enum GtkCalendarDisplayOptions

typedef enum
{
  GTK_CALENDAR_SHOW_HEADING		= 1 << 0,
  GTK_CALENDAR_SHOW_DAY_NAMES		= 1 << 1,
  GTK_CALENDAR_NO_MONTH_CHANGE		= 1 << 2,
  GTK_CALENDAR_SHOW_WEEK_NUMBERS	= 1 << 3,
  GTK_CALENDAR_WEEK_START_MONDAY	= 1 << 4
} GtkCalendarDisplayOptions;

These options can be used to influence the display and behaviour of a GtkCalendar.

`GTK_CALENDAR_SHOW_HEADING`	Specifies that the month and year should be displayed.
`GTK_CALENDAR_SHOW_DAY_NAMES`	Specifies that three letter day descriptions should be present.
`GTK_CALENDAR_NO_MONTH_CHANGE`	Prevents the user from switching months with the calendar.
`GTK_CALENDAR_SHOW_WEEK_NUMBERS`	Displays each week numbers of the current year, down the left side of the calendar.
`GTK_CALENDAR_WEEK_START_MONDAY`	Since GTK+ 2.4, this option is deprecated and ignored by GTK+. The information on which day the calendar week starts is derived from the locale.
