bool	isValid () const

詳細描述

This is an opaque type used to identify custom calendar implementations. The only supported source for values of this type is the backend's calendarId() method. A value of this type whose isValid () is false does not identify a successfully-registered backend. The only valid consumer of values of this type is a QCalendar constructor, which will only produce a valid QCalendar instance if the ID passed to it is valid.
