## Detailed Description

Calendar allows selection of dates from a grid of days, similar to QCalendarWidget.

The dates on the calendar can be selected with the mouse, or navigated with the keyboard.

The selected date can be set through selectedDate. A minimum and maximum date can be set through minimumDate and maximumDate. The earliest minimum date that can be set is 1 January, 1 AD. The latest maximum date that can be set is 25 October, 275759 AD.

      Calendar {
          minimumDate: new Date(2017, 0, 1)
          maximumDate: new Date(2018, 0, 1)
      }

The selected date is displayed using the format in the application's default locale.

Week numbers can be displayed by setting the weekNumbersVisible property to `true`.

      Calendar {
          weekNumbersVisible: true
      }

You can create a custom appearance for Calendar by assigning a CalendarStyle.

## Property Documentation

dayOfWeekFormat : int

The format in which the days of the week (in the header) are displayed.

`Locale.ShortFormat` is the default and recommended format, as `Locale.NarrowFormat` may not be fully supported by each locale (see Locale String Format Types) and `Locale.LongFormat` may not fit within the header cells.

frameVisible : bool

This property determines the visibility of the frame surrounding the calendar.

The default value is `true`.

locale : var

This property controls the locale that this calendar uses to display itself.

The locale affects how dates and day names are localized, as well as which day is considered the first in a week.

The following example sets an Australian locale:

      locale: Qt.locale("en_AU")

The default value is equivalent to `Qt.locale()`.

This property was introduced in QtQuick.Controls 1.6.

maximumDate : date

The latest date that this calendar will accept.

By default, this property is set to the latest maximum date (25 October, 275759 AD).

minimumDate : date

The earliest date that this calendar will accept.

By default, this property is set to the earliest minimum date (1 January, 1 AD).

navigationBarVisible : bool

This property determines the visibility of the navigation bar.

The default value is `true`.

This property was introduced in QtQuick.Controls 1.3.

selectedDate : date

The date that has been selected by the user.

This property is subject to the following validation:

- If selectedDate is outside the range of minimumDate and maximumDate, it will be clamped to be within that range.
- selectedDate will not be changed if `undefined` or some other invalid value is assigned.
- If there are hours, minutes, seconds or milliseconds set, they will be removed.

The default value is the current date, which is equivalent to:

      new Date()

visibleMonth : int

This property determines which month in visibleYear is shown on the calendar.

The month is from `0` to `11` to be consistent with the JavaScript Date object.

See also visibleYear.

visibleYear : int

This property determines which year is shown on the calendar.

See also visibleMonth.

weekNumbersVisible : bool

This property determines the visibility of week numbers.

The default value is `false`.
