Calendar

open class Calendar : Widget, CalendarProtocol

GtkCalendar is a widget that displays a Gregorian 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().

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.

The Calendar type acts as a reference-counted owner of an underlying GtkCalendar instance. It provides the methods that can operate on this data type through CalendarProtocol conformance. Use Calendar as a strong reference or owner of a GtkCalendar instance.

  • Designated initialiser from the underlying `C` data type.

    This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the Calendar instance.

    Declaration

    Swift

    @inlinable
public init(_ op: UnsafeMutablePointer<GtkCalendar>)

    Parameters

    op

    pointer to the underlying object
    Show on GitHub

  • Designated initialiser from a constant pointer to the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the Calendar instance.

    Declaration

    Swift

    @inlinable
public init(_ op: UnsafePointer<GtkCalendar>)

    Parameters

    op

    pointer to the underlying object
    Show on GitHub

  • Optional initialiser from a non-mutating gpointer to the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the Calendar instance.

    Declaration

    Swift

    @inlinable
override public init!(gpointer op: gpointer?)

    Parameters

    op

    gpointer to the underlying object
    Show on GitHub

  • Optional initialiser from a non-mutating gconstpointer to the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the Calendar instance.

    Declaration

    Swift

    @inlinable
override public init!(gconstpointer op: gconstpointer?)

    Parameters

    op

    pointer to the underlying object
