Class Description
An EOTextAssociation object displays a plain or rich text
attribute in an NSText object (Application Kit) by binding the text
object to a string or NSData attribute. It determines the kind of
text received from an object by examining the beginning for signature
codes specific to RTF and RTFD. When writing text back to the object,
the association examines the configuration of the NSText object
to determine the type to use according to the following table:
| Multiple Fonts |
Allows Graphics |
Type Written to Object |
| NO |
NO |
NSString text |
| YES |
NO |
NSData containing RTF |
| YES |
YES |
NSData containing RTFD |
The following tables describe the display objects an EOTextAssociation
can be used with, the aspects of an EOTextAssociation, and the object
keys it takes.
| Usable With |
| NSText, NSTextView, NSCStringText |
| Aspects |
| value |
A text attribute of the selected object. |
| editable |
A boolean attribute of the selected object, which determines whether
the text object is editable. |
| Object Keys Taken |
| delegate |
An EOTextAssociation accepts delegate messages related
to the editing and validation of text; see the NSText, NSTextView,
and NSCStringText class specifications for more information. |
