Transport Interface

Using the Transport Interface

Routing information view

In your transport object, store a reference to your routing information template in
the

transportInfoForm

slot.

To add your own information to the routing information view, you can supply a

BuildText

method. From

BuildText

, call the

AddText

method for each

additional line of text you want to add below the existing elements. Alternatively,
you can add child views to the routing information view.

If you do add additional lines or views to the routing information view that cause it
to increase in height, you must also set the

addedHeight

slot in the routing

information view or in your

BuildText

method (or anywhere before the inherited

ViewSetupFormScript

method is called). In this slot, specify the number of

pixels by which you are increasing the height of the view.

The header view may include editable fields. If the user changes something in an
editable field, you probably want to know about it so that you can save the new
information or perform other operations. The

InfoChanged

message is provided

for this purpose. This message is sent to whatever object you designate when the
header view is closed.

Providing a Routing Slip Template

22

A transport uses a routing slip when sending an item in order to get all the informa-
tion necessary to transmit the item. Since the user interface for the routing slip is
provided by the transport, the application does not need to know anything about
what is required to send the item.
