Field Methods |
The Field type exposes the following members.
Methods| Name | Description | |
|---|---|---|
 | Close | |
| Equals | (Inherited from Object.) |
| EraseAppearance | Removes any appearances associated with the field.
|
| FindInheritedAttribute | Some of the Field attributes are designated as inheritable.
If such an attribute is omitted from a Field object, its value is inherited
from an ancestor node in the Field tree. If the attribute is a required one,
a value must be supplied in an ancestor node; if it is optional and no
inherited value is specified, the default value should be used.
The function walks up the Field inhritance tree in search for specified
attribute.

have any widget annotations or interactive fields.
