About Keyboard Text Input

8

Your application can provide keyboards and keypads for user text input by creating
an object from one of the keyboard view classes or protos:

The

clKeyboardView

class provides a keyboard-like array of buttons that the

user can tap with the pen to perform an action. This class is described in
"Keyboard Views" (page 8-26).

Views and protos for text input and display

edit view

Use the

clEditView

class for basic text input and display.

Objects of this class can display and/or accept text and
graphic data. The

clEditView

automatically creates child

clParagraphView

views for text input and display and

clPolygonView

views for graphic input and display. You

can also include

clPictureView

views in your

clEditViews

.

For more information about this class, see "General Input
Views" (page 8-6).

paragraph views

Use the

clParagraphView

class to display text or to accept

text input.

For more information about this class, see "Paragraph Views"
(page 8-10).

lightweight
paragraph views

If your paragraph view template meets certain criteria, the
Newton system automatically creates a lightweight paragraph
view for you. Lightweight paragraph views are read-only
and use only one font, although they can contain ink. These
views require significantly less memory than do standard
paragraph views.

For more information about lightweight paragraph views, see
"Lightweight Paragraph Views" (page 8-11).

input line protos

You can use one of the input line protos to allow the user to
enter a single line of text, as described in "Using Input Line
Protos" (page 8-12).
