Status view subtypes

Each child view included in a subtype has one important value that controls the
appearance of that child element. For example, the

vProgress

subtype consists of

three child views that have these important values:

statusText

(the string

displayed at the top of the view),

titleText

(the string displayed at the bottom of

the view), and

progress

(an integer indicating the percentage of the page that

should be shown filled with black). The important values for each subtype appear in
Table 22-1. This information is necessary for use in the

SetStatusDialog

method.

A transport specifies the use of a subtype in the status view by passing the subtype
name in the

name

parameter to the

SetStatusDialog

transport method.

Transports can dynamically switch from one status subtype to another without
closing the status view, and can easily update the contents of the status view as well
(for example, updating the progress indicator).
