GKB-Editor User Manual
GKB-Editor User Manual
This section assumes you have already installed the GKB-Editor at your
site, and have successfully loaded the code into a lisp image
containing one of the supported frame systems. For a high level
description of the GKB-Editor and its capabilities, see the GKB-Editor home page. For installation
information, see the Installation Instructions.
To start up the GKB-Editor, type
to the lisp listener. A large window will appear containing a
copyright notice and divided vertically into five parts:
If, when you start, a KB has already been selected (either because you
used the GKB-Editor to select it last time, or because you opened it
using the GFP), you may begin browsing the KB immediately. Otherwise,
you must open and select a KB before you can begin browsing or
editing. If no KB is currently open, you will see the message
Create or Open a KB in the status line where you would
normally see the name and package of the KB.
- menu bar
This is a list of pull-down (or in CLIM 1.1, pop-up) command menus.
The individual commands are each described in the appropriate sections
of this manual.
- status line
This line contains several important pieces of
information. From left to right, it lists the name and package of the
current KB, and
the type of viewer in operation (if you have just started up, this
will be the Class-Instance Hierarchy Viewer).
In addition, if the KB has been modified since it was last saved, this
will be indicated by three asterisks at the far left.
- graphing pane
This large pane containing the copyright notice
will contain graphical output produced by the GKB-Editor. Items
displayed here are sensitive to pointer clicks.
- text pane
This small pane is for textual input and output. Warning
messages from the underlying FRS will appear here, as well as feedback
and instructions from GKB-Editor commands. When asked to select a
frame, you may type in its name here instead of clicking in the
- pointer documentation line
When the pointer passes over a sensitive item, the operations that
correspond to left, middle, and right clicks are listed here. Holding
down, for example, the shift key will show operations that
correspond to the various mouse clicks with the shift key held down.
The first time you open a KB, you must use the Open or New command, which will pop up a
dialogue, prompting you for a filename and other information about the
KB. This information is saved persistently, so the next time you wish
to open the same KB, you need only select its name from the list of
KBs provided when you invoke the Open command. For more information,
see the section on Opening a KB.
The GKB-Editor features four types of viewers, the class hierarchy viewer, the frame relationships viewer, the spreadsheet viewer, and the frame-editing viewer. The original
application window that appears when you first start up the GKB-Editor
is the class hierarchy viewer. From this
window, you can pop up either of the other three viewers. However, many
of the application and knowledge base operations are accessible only
from this original application window, so you must eventually return
to it. Descriptions and examples of each of the available viewers are
given in the appropriate sections. We recommend you read the section
on the class hierarchy viewer first,
before reading about the other three viewers.
