CHAPTER 4

NewtApp Applications

Using NewtApp 4-21

frame containing slots with references to all the viewDef layout templates that

work with that dataDef.

The recommended way to name the corresponding

allDataDefs and

allViewDefs slots is to set the slot names to the data symbol constant,

as shown in the following code examples.

Set the

allDataDefs slot to return a frame with references to all the application’s

dataDefs, as follows:

result := {};

result.(kDataSymbol) := GetLayout("IOUDataDef");

// result.(kData2Symbol) := ... to add a 2nd DataDef

result;

Set the allViewDefs slot to return a frame with references to all the application’s

viewDefs, in a parallel manner, as shown in the following code:

result := {};

result.(kDataSymbol) := {

default: GetLayout("IOUDefaultViewDef"),

notes: GetLayout("IOUNotesViewDef"),

iouPrintFormat: GetLayout("IOUPrintFormat"),

// Use for routing (beaming, mailing, transports):

frameFormat: {_proto: protoFrameFormat},

};

// Use to add a 2nd DataDef:

// result.(kData2Symbol) := {...}

result;

A NewtApp application only accepts stationery when a dataDef has a

superSymbol with a value matching the value of the newtApplication

base view’s

superSymbol slot. For this reason you want the value of the

superSymbol slot to be a unique symbol. This sample application uses

the constant

kSuperSymbol, which is set to the application symbol

'|IOU:PIEDTS|, to set the superSymbol slot.

Using the Required NewtApp Install and Remove Scripts 4

An InstallScript function and RemoveScript function are required to

These scripts are boilerplate functions you should copy unaltered.
