is a set of libraries and tools for building
graphical applications under X11. It's freely available , but
it's past its prime. Its intended successor was Fresco (FrescoFramework
Summary of key InterViews
features from its FAQ:
- Native C++
- Glyphs - lightweight, shareable objects
- Sophisticated layout objects
- Resolution-independent graphics, printing, overlays
- Incremental update, double-buffering
- Graphical editing framework
- Apps: drawing editor, WYSIWYG document editor, interface builder
has touched many lives, in many ways (most of them good)...
- ... architectural ideas ...
- ... living with C++ ...
- ... human interface ideas ...
- ... framework technology ...
- ... builder technology ...
- ... at least two Ph.D. theses ...
- ... mucho consulting ...
- ... numerous commercial products ...
is still useful today, especially to a programmer willing to investigate problems generated by their derivations in a debugger. Several interesting things have been built with it , and a few
significant packages like Target Jr and IvTools
 are still undergoing development. But as a portion of the InterViews
team carried on in their quest to unify structured documents and structured graphics (Fresco ), and one
member of the team started to write about DesignPatterns
extracted from InterViews
, the original tar file was no longer maintained or evolved.
This represented an opportunity for third parties to come out with derivative works, which Vectaport did, layering frameworks  for Motif-look-and-feel, hierarchical documents, large-scale rasters, multi-frame and network editing on top of the original UnidrawFramework
. Other parties (like VRweb) incorporated slightly modified copies of InterViews
into their own software distributions, much like different Linux distributions do with Unix utilities. This is a process open to all-comers, given the BSD style copyright permission notice, and represents a powerful approach to programmers concerned with access to the source where-ever they might need it (a feature of Fresco  as well, by the way. It never went proprietary). -- ScottJohnston
