Text and Ink Input and Display

Using Text

The slots of

protoRichInputLine

are described in "protoRichInputLine"

(page 7-19) in Newton Programmer's Reference.

This proto defines a view that features a label, accepts any kind of input, and is
left-justified. The

protoLabelInputLine

can optionally include a picker.

When the

protoLabelInputLine

does include a picker, the user selects a

choice from the picker. That choice is entered as the text in the input line, and is
marked with a check mark in the picker.

Figure 8-2 shows an example of a

protoLabelInputLine

with and without the

picker option:

An example of a

protoLabelInputLine

The

protoLabelInputLine

is based on a view of the

clParagraphView

class. It has two child views:

The

labelLine

child view uses the

protoStaticText

proto to create the

static text label and to activate the picker if the proto includes one.

The

entryLine

child view uses the

protoInputLine

proto to create the

input field into which the user writes text. The text value entered into this field is
stored in the

text

slot of this view.

You can have your label input line protos remember a list of recent items. To do
this, assign a symbol that incorporates your developer signature to the

'memory

slot of your prototype. The system automatically maintains the list of recent
items for your input line. To access the list, use the same symbol with the

AddMemoryItem

,

AddMemoryItemUnique

,

GetMemoryItems

, and

GetMemorySlot

functions, which are described in "Utility Functions" (page 26-1).
