Routing Interface

entry and even some of the slots from the soup entry. Note that you must use name

references; you cannot specify soup entries directly.

To create a name reference object, use name reference data deﬁnitions registered

with the system in the data deﬁnition registry. There are built-in name reference

data deﬁnitions for e-mail (

'|nameRef.email|), fax ('|nameRef.fax|), and

call (

'|nameRef.phone|) information associated with names from the Names

ﬁle. These data deﬁnitions contain a method,

MakeNameRef, that creates and

returns a name reference.

You can pass a Names soup entry directly to

MakeNameRef, or you can construct

your own simple frame of information that contains the appropriate slots. Fax and

call name references should include the slots

name, phone, and country. E-mail

name references should include the slots

name, email, and country. For more

information about these slots, see “Names Soup Format” (page 16-15) in Newton

Programmer’s Reference.

Here’s an example of how to create a name reference for a fax phone number or an

e-mail address:

// use a Names file entry directly

local myData := aNamesFileEntry; // entry from Names soup

// or create your own fake entry frame based on other info

local myData := {

name:{first:"Juneau", last:"Macbeth"},

phone: "408-555-1234", // fax phone string

email: "[email protected]", // e-mail address string

country: "USA",

}

// then create the fax name reference

aToRef := GetDataDefs('|nameRef.fax|):MakeNameRef(myData,

'|nameRef.fax|);

// or create the e-mail name reference

aToRef := GetDataDefs('|nameRef.email|):MakeNameRef(myData,

'|nameRef.email|);

For more information about name references and the MakeNameRef method, see

the documentation of

protoListPicker in Chapter 6, “Pickers, Pop-up Views,

and Overviews.”

Specifying a Printer 21

For print operations, the printer slot of the item frame speciﬁes which printer to

use. This slot must contain a printer frame. The only valid way of obtaining a

printer frame is from the

currentPrinter variable of the user conﬁguration
