Detailed Description

\inmodule QtCore

Since

6.2

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.
