CHAPTER 21

Routing Interface

21-30 Using Routing

// get an entry from the Names soup to use for the recipient

curs:=GetUnionSoupAlways(ROM_CardfileSoupName):Query(nil);

if curs:Entry() then

begin

// set the toRef slot in the item frame

class := '|nameRef.phone|; // transport addressing class

nameRef := GetDataDefs(class):MakeNameRef(anEntry, class);

item.toRef := [nameRef];

targetInfo := {

targetView: getroot(),

target: {}, // for non-Call transports, add your data here

appsymbol: '|my:SIG|

};

// open the routing slip

OpenRoutingSlip(item, targetInfo);

// returns view (succeeded), or fails with

// nil or 'skipErrorMessage

end;

For the built-in fax and call transports, and for e-mail transports, addressing

information for an item is stored in the

toRef slot of the item frame. E-mail

transports may also store addresses in additional slots such as

cc and bcc. These

slots contain arrays of one or more name reference objects. The example code

above illustrates a name reference created from the data deﬁnition registered for the

addressing class of the transport (in this case the Call transport). For more

information about creating name references, see “Creating a Name Reference”

beginning on page 21-27.

For transports that handle data (unlike the Call transport example here), you must

also pass a target information frame to the

OpenRoutingSlip function. The

target slot in this frame contains the data to send. Note that the target slot can

contain a multiple-item target object, which you can create using the function

CreateTargetCursor.

Supporting the Intelligent Assistant 21

Besides using the standard interface for routing (the Action button), the user can

also invoke routing actions by using the Intelligent Assistant and writing the name

of the action. In order to determine what item to route, the Intelligent Assistant

sends the

GetActiveView message to your application. This method returns the

view to which the

GetTargetInfo message should be sent.

The

GetActiveView method is implemented by default in the root view and

simply returns

self, the current receiver. If this return value is not appropriate for

your application, you must override this method in your application base view.
