Ptolemy is a software environment that provides simulation an code generation capabilities. http://ptolemy.eecs.berkeley.edu describes the Ptolemy project in detail. Ptolemy uses Octtools to represent data internally. A Ptolemy Palette is a Octtools facet that contains other sub-facets. EditPalette class is derived from the EditForest class, and therefore inherits all of its features.
The Palette editor uses the Octtools octls
program
to list the sub-facets in a palette. octls
is part of the
Ptolemy software environment.
