Description

Gnome::Gtk4::Calendar is a widget that displays a Gregorian calendar, one month at a time.

A Gnome::Gtk4::Calendar can be created with .newcalendar().

The date that is currently displayed can be altered with .select-day().

To place a visual marker on a particular day, use .mark-day() and to remove the marker, .unmark-day(). Alternative, all marks can be cleared with .clear-marks().

The selected date can be retrieved from a Gnome::Gtk4::Calendar using .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

Gnome::Gtk4::Calendar 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.
