We plan to publish a series of design notes & other documentation in this section. At the moment there isn't much available but the library will expand over time.
Porting PWLib PSoundChannel to CoreAudio
Andreas Fenkart - who wrote the native PSoundChannel implementation for Mac OS X using CoreAudio - has published his design notes. You can download the Porting PWLib PSoundChannel to MacCoreAudio design notes here (PDF).
XMeeting Graphical User Interface
Ivan Guajana made a documentation about the new GUI that appeared first in XMeeting 0.1. Although only valid for the XMeeting 0.1 release, this documentation contains much insight in the basic design of the GUI. Download it here.
