CHAPTER 22

Transport Interface

Using the Transport Interface 22-21

Providing a Status Template 22

A status template for a transport is based on the proto protoStatusTemplate.

The status template displays status information to the user. A transport should

generally display a status view whenever it is sent the

ReceiveRequest or

SendRequest messages.

You probably won’t need to create your own status template. The

protoTransport

is deﬁned with a default status template named

statusTemplate (based on

protoStatusTemplate), which includes six predefined subtypes, described in

Table 22-1 and shown in Figure 22-1. Each subtype consists of a set of child views

that are added to the base status view. The base status view includes a transport

icon and a close box, to which different child views are added, depending on the

speciﬁed subtype name.
