Removing Words From the Auto-Add Dictionary

10

The

RemoveAutoAdd

function deletes a specified word from both the user and

auto-add dictionaries. This function returns

true

if the word was removed and

returns

nil

if the word was not removed. This method does not remove the word if

it is not present in the auto-add dictionary or if there are case inconsistencies
between the argument to this function and the word actually found in the dictionary.

Using protoCharEdit Views

10

The

protoCharEdit

proto provides a comb-style view that facilitates the

correction of individual characters in misrecognized words. The view provided by
this proto uses an

rcGridInfo

frame internally to provide a horizontal row of

single-character input areas. The system-supplied corrector available from the
picker displayed when the user taps a recognized word makes use of this view.
Figure 10-7 illustrates a typical

protoCharEdit

view.

Example of a

protoCharEdit

view

This section describes how to position a

protoCharEdit

view, how to manipulate

the text string it displays, and how to restrict its input to a specified set of characters.

Positioning protoCharEdit Views

10

There are two ways to position a

protoCharEdit

view within its parent view.

You can set the values of its

top

and

left

slots to values that position it at the top

left corner of the view, or you can provide a similar value for its

viewBounds

slot.

If you specify the values of the

top

and

left

slots, then the

ViewSetupFormScript

method of the

protoCharEdit

view supplies an

appropriate value for the

viewBounds

slot based on the values of the

cellHeight

,

cellWidth

, and

maxChars

slots. On the other hand, if you

provide the values of the

viewBounds

and

cellWidth

slots, then this view

supplies appropriate values for the

maxChars

and

cellHeight

slots for you.

This proto provides useful default values for the

cellWidth

and

cellHeight

slots; it is recommended that you do not change these values.

The technique you use depends on how you want to set the slots that this proto
provides. For detailed information, see "protoCharEdit" (page 8-41) in Newton
Programmer's Reference.
