/**
|
||
* GtkCalendar:
|
||
*
|
||
* `GtkCalendar` is a widget that displays a Gregorian calendar, one month
|
||
* at a time.
|
||
*
|
||
* 
|
||
*
|
||
* A `GtkCalendar` can be created with [ctor@Gtk.Calendar.new].
|
||
*
|
||
* The date that is currently displayed can be altered with
|
||
* [method@Gtk.Calendar.select_day].
|
||
*
|
||
* To place a visual marker on a particular day, use
|
||
* [method@Gtk.Calendar.mark_day] and to remove the marker,
|
||
* [method@Gtk.Calendar.unmark_day]. Alternative, all
|
||
* marks can be cleared with [method@Gtk.Calendar.clear_marks].
|
||
*
|
||
* The selected date can be retrieved from a `GtkCalendar` using
|
||
* [method@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.
|
||
*
|
||
* # CSS nodes

* ```

* calendar.view

||
* ╰── label[.day-name][.week-number][.day-number][.other-month][.today]
|
||
* ```
|
||
*
|
||
* `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.
