CHAPTER 10

Recognition: Advanced Topics

Using Advanced Topics in Recognition 10-35

Usually, you do not need to load the auto-add dictionary into RAM yourself—the

system does so automatically whenever the Personal Word List slip is opened or

the system is reset. However, the system provides the

LoadAutoAddDictionary

function for your convenience.

Disabling the Auto-Add Mechanism 10

When the cursive recognizer is enabled, words not appearing in any of the

currently enabled dictionaries are added to the auto-add and user dictionaries

automatically as they are recognized or corrected. The value of the

doAutoAdd

slot in the system’s user conﬁguration data controls this default behavior.

However, not all input to a view is appropriate to add to dictionaries; for example,

consider a spreadsheet that allows the user to select cells by entering row and

column numbers—you wouldn’t want to add these strings to the dictionaries as

they are recognized. To disable the automatic addition of new words to the user and

auto-add dictionaries, you can use either of the following techniques:

■ Set the _noautoadd slot in the view or its recConfig frame to a

non-

nil value.

■ Set the _noautoadd slot in the word’s wordInfo frame to a non-nil

value. You can get a word’s

wordInfo frame by calling the

GetCorrectionWordInfo function from within the view’s

ViewWordScript method.

Alternatively, you can set the value of the

doAutoAdd slot in the system’s user

conﬁguration data to

nil and call the ReadCursiveOptions function; however,

it is not recommended that you change user conﬁguration settings without ﬁrst

obtaining conﬁrmation from the user.

Adding Words to the Auto-Add Dictionary 10

The AddAutoAdd function adds a speciﬁed word to both the user and auto-add

dictionaries. This function returns the value

true after adding the word

successfully. The word is not added if its unpunctuated form is present in the

standard set of dictionaries enabled by the

vCharsAllowed ﬂag.

If the auto-add dictionary already contains its maximum of 100 words, this

function does not add the new word but displays the notify icon instead. When the

user taps the notify icon, it posts a notify action that displays the Recently Written

Words slip. The user can then edit the Recently Written Words slip before

attempting to add more words; if the user responds immediately, no new words are

lost. For more information on the notify icon and notify actions, see Chapter 17,

“Additional System Services.”
