ΓòÉΓòÉΓòÉ 5. Glossary ΓòÉΓòÉΓòÉ

This is an alphabetical list of key ObjectVision terms.

active form
The form currently being completed or edited. It appears in front of all other
forms in the application.

calculated field
A field that uses a tree to calculate its value. When selected, a calculated
field is indicated by a solid outline with an inner dotted line.

Clipboard
A temporary holding place for cut or copied objects. You can paste the contents
of the Clipboard into any ObjectVision application. When you cut or copy
something else, the contents of the Clipboard are replaced with the new
material.

event tree
A tree that performs an action after an event condition has occurred to the
tree's object.

field
A uniquely named object that contains a value either entered by a user,
calculated, or delivered by a link. Fields are the basic elements of a form.

field sequence
The order of user movement through fields on a form. Field sequence is
determined by the physical ordering of the fields from left to right and top to
bottom. The relative position of a field's bottom right corner determines
whether it is before or after another field.

font
A typestyle used for a field label, field value, or text object.

form
The container ObjectVision uses to hold objects such as fields, tables, or
graphics. A form is the primary interface between ObjectVision applications and
users.

form completion
The mode a user is in when filling in an ObjectVision application. After a form
is completed, the status indicator in the title bar reads (Complete).

Goal form
The top form in the application's stack of forms. It appears when you first
open the ObjectVision application. When you choose another form, it becomes the
Goal form.

guided completion
The technique ObjectVision uses to automatically select fields for data entry.
When you press Enter, the next field requiring input is selected. If you
interrupt this method of selection by selecting another field, you can restart
guided completion with File|Resume.

links
The part of an ObjectVision application used to read from and write to ASCII,
Paradox, dBASE, Database Manager, Btrieve data files or DDE-supported
applications.

node
A generic term for part of a tree. A node can be an empty node, a simple or
complex branch node, a root node, or a conclusion node.

override
A new value that is typed over a calculated one. After a user overrides a
calculated value, the field displays a dot pattern. Field|Calculate restores
the calculated value.

protection
A field property that prevents users from changing a calculated field value or
viewing a tree.

row pointer
A right-pointing triangle that indicates the current or active row in a table
object. The row pointer appears to the left of the first column in a table
object.

Scratchpad form
The form ObjectVision automatically creates to display any field in the
application that's not on a form.

selected field
The field that is outlined with a solid line or a solid line combined with a
dot pattern or dotted line.

stack
The order of forms in an ObjectVision application.

table object
An ObjectVision form object that displays sets of one or more database records
at a time.

tree
A graphical display of calculations or actions. Trees are like flow charts
because they evaluate a condition, and based on the result, perform the next
branch or conclusion.

values
The data contained in fields. A user can type values, select them from a list,
or check them; an ObjectVision application can calculate values or read them
from an external data file.

value tree
A tree used to calculate a value for its field. Value trees are properties of
fields and columns only.
