CHAPTER 10

Recognition: Advanced Topics

Using Advanced Topics in Recognition 10-29

In addition to setting the view’s vCustomDictionaries ﬂag, you need to create

dictionaries slot in either the view or its recConfig frame. The

dictionaries slot stores a single dictionary identifier or an array of dictionary

identiﬁers. You need to install the custom dictionary in this slot using code similar

to the following example.

// vCustomDictionaries flag already set

dictionaries := mySpecialDictionary;

To use system-supplied dictionaries in addition to your custom dictionary, you can

enable additional view ﬂags in the Entry Flags editor in NTK or set these

additional ﬂags procedurally. If you prefer to set view ﬂags procedurally, you must

use the

Bor function to bitwise OR the vCustomDictionaries ﬂag with any

bits already set in the

viewFlags slot. In either case, your custom dictionary must

still be speciﬁed in the

dictionaries slot.

Note that some view ﬂags enable combinations of system dictionaries. If you want

to specify explicitly which system dictionaries the view can use, set no dictionary-

enabling ﬂags other than the

vCustomDictionaries ﬂag and use system-

supplied dictionary ID constants to add speciﬁc dictionaries to the

dictionaries

slot. For descriptions of the system-supplied dictionary ID constants, see

“System-Supplied Dictionaries” (page 8-16) in Newton Programmer’s Reference.

The following code fragment shows how you can specify dictionaries explicitly

by including the appropriate constants as elements of the array in the

dictionaries slot.

dictionaries :=[mySpecialDictionary, kUserDictionary,

kCommonDictionary]

Regardless of the order of elements in the dictionaries array, the system

always searches the user dictionary ﬁrst. The system then searches all of the

speciﬁed dictionaries in the order that they appear in the

dictionaries array. In

general, the order in which this array’s items appear is not critical, except in the

case of conﬂicting capitalization information for representations of the same word

in multiple dictionaries. When multiple dictionary entries match the input, the

system uses the ﬁrst dictionary entry that was matched.

Note that the printed recognizer can always return words not present in

dictionaries. Only the cursive recognizer may be restricted to returning only words

present in dictionaries (and then only when letter-by-letter recognition is not

enabled). To test your dictionary settings, use the cursive recognizer while its

letter-by-letter option is disabled.
