Perhaps you could simplify things by laying out 4 separate views on a
scene and rendering the IDLgrScene on you draw widget.

It's interesting how the lack of automatic layout of object graphics
is initially perceived as a weakness. Some authors of IDL packages try
to
automate layout by making wrapper classes to manage the object
graphics. I did this at first, however, now I leave layout as an
exercise for the caller. This gives the caller more chance to mix and
match layouts.

Actually , Ihave a separate class for managing and laying out views on
a scene. I use the /GRID_LAYOUT option on my atom tree (http://
barnett.id.au/idl/nmtkatomtree.html). For some instances I don't find
atom tree useful, so I defer to managing the atoms by hand.

Anyway, my OO jargon is probably not going to help you just yet. Have
you used IDL revolution (http://ittvis.com/codebank/search.asp?
FID=473) at all? Was it useful as a learning experience?
