Stationery

Using Stationery

Here is an example:

TextScript: func(item,target)

begin
item.text := "IOU " & target.(kDataSymbol).who

&& "owes me" &&
NumberStr(target.(kDataSymbol).howMuch);

item.text;
end;

Creating ViewDefs

5

ViewDefs may be based on any of the generic view protos. You could use, for
instance, a

clView

, which has very little functionality. Or, if you wanted a picture

to display behind your data, you could base your viewDef on a

clPictureView

.

Routing and printing formats are also implemented as viewDefs. You can learn
more about using special protos to create routing and printing formats in Chapter 21,
"Routing Interface."

Note that these are just a few examples of views you may use as a base view in
your viewDef. Your viewDef will function as expected, so long as the required slots
are set and the resulting view template is registered, either in the

allviewDefs

slot of the

newtApplication

base view or through the

InstallScript

function of an auto part.

You may create the viewDef for the auto part that extends the Notes application by
using a

clView

as the base view. Create an NTK view template, named

iouDefaultViewDef

, in which a

clView

fills the entire drawing area. Then

save the view template file (using the Save As menu item) as

iouDefaultViewDef

.

You can now set the slots as follows:

Set the

name

slot to

"IOU Info"

. This string appears in the Show button, if

there is one.

Set the

symbol

slot to

'default

. At least one of the viewDefs associated with

a dataDef must have

'default

as the value of its

symbol

slot.

Set the

type

slot to

'viewer

. The three system-defined types for viewDefs are

'editor

,

'viewer

, and

'routeFormat

. You may define others as you wish.

Set the

viewDefHeight

slot to 176 (of the four slot views that will be added

to this viewDef, each is 34 pixels high plus an 8-pixel separation between them
and an 8-pixel border at the bottom).

Set the

viewBounds

slot to 0, 0, 0, 0.

Set the

viewJustify

slot to horizontal parent full relative and vertical parent

full relative.
