bvs%carlisle@Sun.COM (Bruce V. Schwartz / Marketing Technical Support) (01/05/89)
This is the new version of the browser that was hidden on the SUG SEX machine in a miscellaneous/unorganized directory. So you may not have seen this even if you got SEX at SUG. Many changes in November 1988. Integrated several of Richard Hess's improvements. New features include improved scrolling, caching of browsed classes, addition of the NoClass class for browsing the systemdict, better decompilation of dictionaries, process control (new request cancels previous), better error handling, faster sorting, and looks better on B/W screen. The browser is built on the classes defined in pw.ps. The class browser has 5 panes. It is similar in appearance to the Smalltalk browser. The first pane on the top of the window contains the list of classes in the server. The next 3 contain the list of methods, class variables, and instance variables associated with the selected class in the first pane. The bottom pane is used to display information about the current selection. Bruce V. Schwartz Sun Microsystems bvs@sun.com #! /bin/sh # This is a shell archive, meaning: # 1.
