[comp.windows.interviews] Viewers/Editors 3.0 vs 2.6

bcy@C3SERVE.C3.LANL.GOV (Bonnie Yantis) (06/28/91)

We need to use a viewer object and an editor object in a
Unidraw type application.  We're having a trouble mixing
the 2.6 and 3.0 objects and we'd like to be able take advantage
of both Unidraw and glyphs.

 
(1) Will there be a viewer object and an editor object in
    subsequent releases?
 
(2) Since the standard 2.6 graphic library doesn't run with 
    3.0, will we be able to use a viewer with the new image library?
    (We'd like to take advantage of glyphs.)
 
(3) We need something working by Oct 1.  Would you recommend 
 
    a. Doing the application in 2.6 and converting to 3.0+ later
       when (1) (hopefully!) happens or...
 
 
    b. Trying to use glyphs and hacking together something
       with canvases to represent a viewer 
 

 
We'd appreciate any feedback you can give.  Thanks in advance.

Yes.

Yes, the plan is to integrate Unidraw and glyphs, while preserving the Unidraw
class interfaces as much as possible.

If you want to use Unidraw features, (a) is the safer approach.  If you just want to view
structured graphics, you could look at how doc does it with glyphs and see if you could
adapt that.
