Transport Interface

22-22 Using the Transport Interface

Figure 22-1 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 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).
