Detailed Description
Represents a null calendar class; that is, a calendar which contains no information and provides no capabilities.
The null calendar can be passed to functions which need a calendar object when there is no real calendar available yet.
CalendarNull can be used to implement the null object design pattern: pass a CalendarNull object instead of passing a 0 pointer and checking for 0 with each access.

Constructor & Destructor Documentation
CalendarNull::CalendarNull | ( | const KDateTime::Spec & | timeSpec | ) | [explicit] |
Construct Calendar object using a time specification (time zone, etc.
Private class that helps to provide binary compatibility between releases.
). The time specification is used for creating or modifying incidences in the Calendar. It is also used for viewing incidences (see setViewTimeSpec()). The time specification does not alter existing incidences.
- Parameters:
-
timeSpec time specification
For internal use only.
Definition at line 47 of file calendarnull.cpp.
CalendarNull::CalendarNull | ( | const QString & | timeZoneId | ) | [explicit] |
Constructs a null calendar with a specified time zone timeZoneId
.
- Parameters:
-
timeZoneId is a string containing a time zone ID, which is assumed to be valid. If no time zone is found, the viewing time specification is set to local clock time. Example: "Europe/Berlin"
