Recognition: Advanced Topics
10-22 Using Advanced Topics in Recognition
When the view receives input, it uses parent inheritance to find configuration
information. If a
_recogSettings slot exists in the view’s _parent chain, the
view uses the value of this slot, along with values supplied by an optional
recConfig frame and values inherited from the system’s user configuration data.
The recToggle view’s ViewSetupFormScript method uses the value of the
_recogSettings slot to set the state of the recToggle view. To restore the
recognition settings that were in effect the last time your application was used, you
can save the value of the
_recogSettings slot when the application closes and
restore the value of this slot when the application reopens. If you prefer that the
recToggle view always open to a default setting, rather than a saved one, you
can place the value nil in the _recogSettings slot when your application opens.
Providing the _recogPopup Slot 10
You can customize the appearance and behavior of your recToggle view by
providing a _recogPopup slot in its view template. This slot contains an array of
symbols corresponding to items included in the picker that the recToggle view
displays. The first item in the array appears at the top of the picker and specifies the
default recognizer enabled by the
recToggle view. The picker includes subsequent
items in the order in which they appear in the array.
Table 10-2 summarizes the symbols that may appear in the _recogPopup slot,
along with the corresponding item each produces in the recToggle picker.
To specify that the recToggle view enable a default recognizer other than the one
specified by the first symbol in the _recogPopup array, your recToggle view’s
template can provide a defaultItem slot. This slot holds an integer value
specifying the array element to be used as the default.
