gglEvent (Type of variable)

The gglEvent type is used to describe and modify an event of a calendar. The calendar is described via the gglCalendar type. This calendar is used by the Google Calendar service.

Note: See Declaring a variable for more details on the declaration of this type of variable and the use of WLanguage properties.

Caution: the access to the Google Calendars changes from November 17, 2014

From November 17 2014, Google is only using the Google API version 3 (Google API version 2 is abandoned). This change of version has modified the exchange format of data used by the functions for accessing the Google Calendars.

An "OAuth 2.0" authentication is now required to access this service. This authentication mode requires:

the declaration of the application in the Google console. To use the Google Calendars, the application must use the "Calendar API" service.
the use of new properties in the gglConnection variable.

See the help about GglConnect for more details.

Caution: The gglCalendar, gglEvent and gglLocation variables are also modified. Some properties become obsolete with the Google API version 3: they must not be specified anymore.

Example

// Connection to Google
Cnt is gglConnection
Cnt..Email = "vince@gmail.com"
Cnt..Password = "azerty"
Cnt..ApplicationName = "MyApp-01"
IF GglConnect(Cnt) = False THEN
Error(ErrorInfo())
END
...
// Retrieve the array of available calendars
arrCalendars is array of gglCalendar
arrCalendars = GglListCalendar(Cnt)
// Retrieve all the events of the first calendar
GglFillCalendar(Cnt, arrCalendars[1])
// Browse the events
Evt is gglEvent
FOR EACH Evt OF arrCalendars[1]
Trace(Evt..Title)
END

Versions 20 and later

Managing the dates and their time zone

Further to the use of the "OAuth 2.0" authentication, the management of dates was modified. All the dates returned by GglGetCalendar, GglListCalendar, ... in the gglEvent variables are using the time zone of the local computer. Therefore, they can be directly used in a Calendar control with the current time zone.

To convert them into a specific time zone, you have the ability to use DateTimeLocalToTimeZone or DateTimeLocalToUTC.

You have the ability to retrieve the time zone of the accessed calendar via the ..TimeZone property of the gglCalendar variables. The returned value corresponds to the name of the time zone, issued from the "tz" database (or Olson database). This name can be directly used by DateTimeLocalToTimeZone.
