@description: this file generates a general agenda of all items of the
|

|
|
version info:
|
|
-------------
|
|
-> version 2.2 : Patrick Cool, patrick.cool@ugent.be, november 2004
|
|
Personal Agenda added. The user can add personal agenda items. The items
|
|
are stored in a dokeos_user database because it is not course or platform
|
|
based. A personal agenda view was also added. This lists all the personal
|
|
agenda items of that user.
|
|
|
|
-> version 2.1 : Patrick Cool, patrick.cool@ugent.be, , oktober 2004
|
|
This is the version that works with the Group based Agenda tool.
|
|
|
|
-> version 2.0 (alpha): Patrick Cool, patrick.cool@ugent.be, , oktober 2004
|
|
The 2.0 version introduces besides the month view also a week- and day view.
|
|
In the 2.5 (final) version it will be possible for the student to add his/her
|
|
own agenda items. The platform administrator can however decide if the students
|
|
are allowed to do this or not.
|
|
The alpha version only contains the three views. The personal agenda feature is
|
|
not yet completely finished. There are however already some parts of the code
|
|
for adding a personal agenda item present.
|
|
this code was not released in an official dokeos but was only used in the offical
|
|
server of the Ghent University where it underwent serious testing
|
|
|
|
-> version 1.5: Toon Van Hoecke, toon.vanhoecke@ugent.be, december 2003
|
|
|
|
-> version 1.0: Eric Remy, eremy@rmwc.edu, 6 Oct 2003
|
|
The tool was initially called master-calendar as it collects all the calendar
|
|
items of all the courses one is subscribed to. It was very soon integrated in
|
|
Dokeos as this was a really basic and very usefull tool.
