target

The object being acted upon.

Sometimes the target consists of multiple items,
for example, when multiple items are selected
from an overview for sending.

template

A frame that contains the data

description of an object (usually a view). A
template is intended to be instantiated at run
time. See also proto.

text run

A sequence of characters that are all

displayed with the same font specification. Text
is represented in paragraph views as a series of
text runs with corresponding style (font spec)
information. See also font spec.

tick

A sixtieth of a second.

transport

A NewtonScript object that

provides a communication service to the
Newton In/Out Box. It interfaces between the In/
Out Box and an endpoint. Examples include the
print, fax, beam, and mail transports. See also
endpoint.

transport

A special type of Newton

application used to send and/or receive data.
Transports communicate with the In/Out Box on
one end and typically to an endpoint object on
the other end. Examples include the built-in
transports such as print, fax, and beam. See also
endpoint.

user proto

A proto defined by an application

developer, not supplied by the system.

view

The object instantiated at run time from a

template. A view is a frame that represents a
visual object on the screen. The

_proto

slot of

a view references its template, which defines its
characteristics.

view class

A primitive building block on

which a view is based. All view protos are based
directly or indirectly (through another proto) on
a view class. The view class of a view is
specified in the

viewClass

slot of its template

or proto.

view definition

A view template that defines

how to display data from a particular data
definition. A view definition is registered with
the system under the name of the data definition
to which it applies. The shortened term viewDef
is sometimes used. See also data definition.

wedge

A pie-shaped segment of an oval,

bounded by a pair of radii joining at the oval’s
center. Contrast with arc.
