|
||
* @Short_description: Displays a calendar and allows the user to select a date
|
||
* @Title: GtkCalendar
|
||
*
|
||
* #GtkCalendar is a widget that displays a Gregorian calendar, one month
|
||
* at a time. It can be created with gtk_calendar_new().
|
||
*
|
||
* The date that is currently displayed can be altered with
|
||
* 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 selected date can be retrieved from a #GtkCalendar using
|
||
* gtk_calendar_get_date().
|
||
*
|
||
* Users should be aware that, although the Gregorian calendar is the
|
||
* legal calendar in most countries, it was adopted progressively
|
||
* between 1582 and 1929. Display before these dates is likely to be
|
||
* historically incorrect.

* GtkCalendar has a main node with name calendar. It contains a subnode called header
|
||
* containing the widgets for switching between years and months.
|
||
*
|
||
* The grid subnode contains all day labels, including week numbers on the left (marked
|
||
* with the .week-number css class) and day names on top (marked with the .day-name
|
||
* css class).
|
||
*
|
||
* Day labels that belong to the previous or next month get the .other-month style class.
|
||
* The label of the current day get the .today style class.
|
||
*
|
||
* Marked day labels get the :selected state assigned.
