Description

TCalendarDialog is a TExtCommonDialog descendant which implements a calendar dialog used to select a date from a TCalendar control. It provides a Date property that contains the date used when selecting a date using the Calendar control displayed in the dialog.

TCalendarDialog creates and configures a TForm instance that is displayed in the Execute method for the dialog. The form uses the Title, DialogPosition, DisplaySettings, and Date properties assigned in the class. A new TCalendar control is created for the form, and stored in the Calendar property. Methods which implement the event handlers for the calendar control are also assigned. The form instance is displayed modally, and the modal result is captured in the UserChoice property. Date is updated when a calendar date is selected while the form is active.

TCalendarDialog.Date		The selected Date for the calendar dialog.
TExtCommonDialog.DialogPosition		Specifies the position where the dialog is displayed.
TExtCommonDialog.DlgForm		Contains the form displayed modally for the custom-drawn dialog.
