First - Is your application real-time? Or simply interactive?
For non-real-time interactive applications, I prefer to use multiple
pfPipewindow's instead of multiple channels one pfPipeWindow.
Do you intend to have multiple windows on screen at the same time? If so, are
these windows independant? Can they be moved, minimized, lower and raised
independantly? If yes then you need multiple pfPipeWindow's.
However, imagine a 3-D graphics editor with 4 views of the object being drawn.
This would be a perfect case for multiple pfChannel's since the application
should not allow the views to be moved at will be the user.
I suggest you carefully look at the two examples multiwin.c and multichan.c
located in /usr/share/Performer/src/pguide/libpf/C.
