NewtApp Applications

Using NewtApp

3. Set the

masterSoupSlot

to the symbol

'IOUSoup

. This correlates to the

name of the soup as it is set up in the

newtApplication.allSoups

slot.

See "Setting Up the Application Soup," beginning on page 4-15.

4. Add the

forceNewEntry

slot. Leave it with the default value

true

.

This causes a new entry to be created if a user tries to open an empty folder.

5. Add a

viewFormat

slot and set the

Fill

value to

White

. This makes the data

it displays look better and keeps anything from inadvertently showing through.
In addition, the white fill improves the speed of the display and enhances view
performance.

6. Set the name slot to a string like

"Overview"

.

7. Add a

centerTarget

slot and set it to

true

. This assures that the entries are

centered for display in the Overview.

Once the name of the status bar is declared to the application base view (in the

newtApplication.statusBarSlot

), you may control the appearance and

disappearance of buttons on the status bar, from the layout view, as needed.

To do this, you must specify which buttons should appear on the status bar by
using the slots

menuLeftButtons

and

menuRightButtons

. Each of these is

an array that must contain the name of the button proto(s) that you wish to appear
on the menu bar's left and right sides. When you use these arrays, the button protos
listed in them are automatically placed correctly on the status bar, according to the
current human interface guidelines.

To appropriately set up the appearance of the status bar for display in the Overview,
first add the optional slots

menuLeftButtons

and

menuRightButtons

. The

buttons you name in these slots replace the menu bar buttons from the main layout,
since the

statusBarSlot

is set there.

Set the

menuLeftButtons

slot to an array that includes the protos for the

Information and New buttons. These buttons are automatically laid out on the
status bar, going from left to right.

menuLeftButtons:=[

newtInfoButton,
newtNewStationeryButton,
]

Set the

menuRightButtons

slot to an array that includes the protos for the

Action and Filing buttons. These buttons are automatically laid out on the status
bar from right to left.
