Recognition

Using the Recognition System

The

vNoSpaces

flag must appear in an evaluate slot named

textFlags

that you

create in the view. The

vSingleUnit

flag appears in the view's

viewFlags

slot,

as usual.

Forcing Capitalization

9

The

vCapsRequired

flag directs the system to capitalize the first letter of each

word returned by the recognizer before displaying the text in the view.

Setting the

vCapsRequired

flag does not affect the recognizer's behavior--it

affects post-processing performed on the recognizer's output before it is returned to
the view.

Justifying to Width of Parent View

9

Setting the

vWidthIsParentWidth

flag for a view based on the

clParagraphView

class causes the view to extend its right boundary to match

that of its parent automatically.

The

vWidthIsParentWidth

flag must appear in an evaluate slot named

textFlags

that you create in the view.

Like other flags set in the

textFlags

slot, the

vWidthIsParentWidth

flag

does not affect the recognizer's behavior--it affects post-processing performed on
the recognizer's output before it is returned to the view.

Restricting Input to Single Lines or Single Words

9

Including the

oneLineOnly

flag in your view's

viewJustify

slot causes the

view to accept only a single line of text input, with no word wrapping provided.

You can restrict input to a single word by including the

oneWordOnly

flag in the

view's

viewJustify

slot. If this flag is set, the view replaces the currently

displayed word with the new one when the user writes in the view. You can also
restrict input to single characters by using this flag in conjunction with a custom
dictionary of single letters.

For more information on these flags, see their descriptions in Chapter 3, "Views."
For information on the use of custom dictionaries, see "Using Custom
Dictionaries" beginning on page 10-24.

Validating Clipboard and Keyboard Input

9

It is possible for the user to enter invalid values in fields by dragging text from the
Clipboard or by using a keyboard to type in the field. For example, setting the

vPhoneField

flag normally restricts input to numeric values in phone number

formats; however, the user can still enter invalid values in such a field by dragging
