NewtApp Applications

Using NewtApp

Follow these steps to ready your application for the slot views:

1. Drag out a

newtEntryView

proto on top of the

newtLayout

proto.

2. Optional. Name it

theEntry

.

There are no unusual slots to set in an entry view. Therefore, you are ready to add
the header and slot view protos.

3. Drag out a

newtEntryPageHeader

across the top of the

newtEntryView

.

4. Under the header, drag out a

newtStationeryView

proto that covers the rest

of the entry view. This special view is not be visible; its function is to provide a
bounding box for the viewDef that will eventually be displayed.

The layout should look like the screen shot shown in Figure 4-9.

The information button and picker.

Several slots in the

newtApplication

base view enable you to identify the

stationery in your application. These slots include the

allViewDefs

,

allDataDefs

, and

superSymbol

slots.

To see how to create the stationery used as part of this application,
consult Chapter 5, "Stationery." The

allDataDefs

and

allViewDefs

slots, which are discussed here, contain

references to those dataDefs and viewDefs.

The

allDataDefs

and

allViewDefs

slots are assigned references to the NTK

layout files containing your dataDefs and viewDefs. Once this is done, the
NewtApp framework automatically registers your stationery with the Newton
system registry when your application is installed on a Newton device.

Each

allDataDefs

and

allViewDefs

slot contains frames that are required to

contain slots with identical names, to indicate the dataDefs and viewDefs that work
together. (A dataDef must be registered with its set of viewDefs because dataDefs
use viewDefs to display their data.)

In the

allDataDefs

slot is a frame containing a reference to the NTK layout

template for a single dataDef. In the frame within the

allViewDefs

slot is the
