or typing them. To prevent invalid input by these means, you can implement a

ViewChangedScript

method that validates its view's input.

Using the vAnythingAllowed Mask

9

The

vAnythingAllowed

mask can be used only with views based on the

clEditView

class. When used by itself, this mask sets all of the bits in the view's

input mask, potentially enabling all of the system-supplied recognizers and
dictionaries. However, the actual recognition behavior of views that use this mask
varies according to current user preference settings.

For a view that sets the

vAnythingAllowed

mask, the recognition system

replaces the set of view flags you've specified with a set of flags derived from the
current settings of user preferences that affect recognition.The actual set of
recognizers enabled for the view is controlled by

user preferences specified in the system's user configuration data.

the application's

protoRecToggle

view, if it has one.

the view's

recConfig

frame, if it has one.

Slots in the system's user configuration data specify recognition behaviors that all
views inherit. However, an optional

protoRecToggle

view can specify different

behaviors for individual views by overriding values inherited from user configuration
data. Similarly, each view can provide a

recConfig

frame that overrides settings

specified by the

protoRecToggle

view or the system's user configuration data.

Thus, in practice, the

vAnythingAllowed

mask usually is not what its name

implies: if any bit in this mask is turned off (by another flag, or by a

recToggle

view, for example), the input mask is no longer

vAnythingAllowed

.

The built-in Notepad application provides a good example of the behavior of views
that use the

vAnythingAllowed

mask, including the use of a

protoRecToggle

view to change recognition settings.
