- Package:
- com.webobjects.eointerface
Class Description
In a Java Client application (using Swing), an EOTextAssociation object displays a plain text attribute in an EOTextField, EOTextArea, or EOFormCell by binding the text object to a string. Text is written back to the object as a String.
In a Cocoa application, an EOTextAssociation object displays a plain or rich text attribute in an NSText object 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 |
| Usable With |
| com.webobjects.eointerface.swing: EOTextField, EOTextArea, EOFormCell |
| com.webobjects.eointerface.cocoa: NSText, NSTextView |

Constructors
EOTextAssociation
public EOTextAssociation(Object aDisplayObject)
You normally set up associations with the Interface Builder application, in which case you don't need to create them programmatically. However, if you do create them up programmatically, setting them up is a multi-step process. After creating an association, you must bind its aspects and establish its connections.
