- @author: Eric Remy (initial version)
- @version: 2.2 alpha
- @description: this file generates a general agenda of all items of the
- courses the user is registered for
- ==============================================================================
- 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.
