Text and Ink Input and Display

Using Text

Once a lightweight paragraph view has been instantiated, you cannot dynamically
change the view flags to make it an editable view, or add multistyled text by
providing a

styles

slot, since this type of view object doesn't support these

features. If you need this functionality for an existing lightweight paragraph view,
you'll have to copy the text out of it into an editable paragraph view.

Using Input Line Protos

8

Input line protos provide the user with single lines in which to enter data. There are
four input line protos available:

protoInputLine

is a one-line input field that defines a simple paragraph

view in which the text input is left-justified.

protoRichInputLine

is the text and ink equivalent of

protoInputLine

.

protoLabelInputLine

is a one-line input field that includes a text label and

can optionally include a pop-up menu known as a picker.

protoRichLabelInputLine

is the text and ink equivalent of

protoLabelInputLine.

This proto defines a view that accepts any kind of text input and is left-justified.
Below is an example of a what a

protoInputLine

looks like on the

Newton screen:

The

protoInputLine

is based on a view of the

clParagraphView

class. It

has no child views.

The following is an example of a template using

protoInputLine

:

myInput := {...
_proto: protoInputLine,
viewJustify: vjParentRightH+vjParentBottomV,
viewLineSpacing: 24,
viewBounds: SetBounds( -55, -33, -3, -3),
...}

The slots of the

protoInputLine

are described in "protoInputLine" (page 7-17)

in Newton Programmer's Reference.

This proto works exactly like

protoInputLine

. The only difference is that

protoRichInputLine

allows mixed ink and text input, as determined by the

current user recognition preferences.
