The dates on the calendar can be selected with the mouse, or navigated with the keyboard. The selected date can be set through \l selectedDate. A minimum and maximum date can be set through \l minimumDate and \l 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. 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 \c true. You can create a custom appearance for Calendar by assigning a7172737475767778798081828384858687888990919293949596979899100101102103104105106107108109110111112113114115116117118119120121122123124125126127128129130131132133134135136137138139140
