This class was introduced in Qt 6.2.
bool | isValid() const |
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.
See also QCalendar and QCalendar::System.
Returns true
if this is a valid calendar implementation identifier, false
otherwise.
See also QCalendar.
