The Tycho graphics editor is still in a preliminary form. It is currently used as a base class for more specialized editors like the graph display widgets. The features it currently provides are described below.
Support for title, subtitle, author, version and copyright header
information. The idea here is to provide a common look for titles
across a wide variety of graphical display and edit widgets in Tycho
that will need titles. The Title
command in the
Edit
menu invokes a
dialog that facilitates entering such titles. This dialog lists only
title types that do not already exist. To edit an existing title type,
use the Edit Item
command in the Edit
menu.
What goes in the version title depends on the version control system you will use. If you use SCCS, then the following will work well:
Version: %W% %G%The SCCS system will translate this when the file is checked in to, for example,
Version: @(#)filename 1.2 12/13/96Similarly, the copyright line used at Berkeley looks like this:
Copyright (c) 1995-%Q%, The Regents of the University of California.The SCCS version control system translates this to
Copyright (c) 1995-1996, The Regents of the University of California.
The contents of the canvas in a graphical widget can be converted
to postscript and sent to a printer. The
Print
command in the File
menu opens a
dialog box that controls various parameters of this process.
The contents of the canvas in a graphical widget can be converted
to a number of file formats, including
encapsulated postscript
GIF, and
XWD.
Currently, the latter two work on Unix installations only.
The Export
command in the File
menu opens a
dialog box that controls various parameters of this process.
