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()
.
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 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).
gchar* (*GtkCalendarDetailFunc) (GtkCalendar *calendar, guint year, guint month, guint day, gpointer user_data);
This kind of functions provide Pango markup with detail information for the
specified day. Examples for such details are holidays or appointments. The
function returns NULL
when no information is available.
calendar : |
a GtkCalendar. |
year : |
the year for which details are needed. |
month : |
the month for which details are needed. |
day : |
the day of month for which details are needed.

Since 2.14
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, GTK_CALENDAR_SHOW_DETAILS = 1 << 5 } 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

Just show an indicator, not the full details
text when details are provided. See gtk_calendar_set_detail_func() .

void gtk_calendar_set_detail_func (GtkCalendar *calendar, GtkCalendarDetailFunc func, gpointer data, GDestroyNotify destroy);
Installs a function which provides Pango markup with detail information for each day. Examples for such details are holidays or appointments.
