Inherits from:
EOCocoaSimpleTextPlugin : EOTextAssociation.TextPlugin (EOInterface) : EOValueAssociation.ValuePlugin (EOInterface) : EOWidgetAssociation.WidgetPlugin (EOInterface) : Object
Implements:
NSDisposable
Package:
com.webobjects.eointerface.cocoa


Class Description


In a Cocoa application, an EOCocoaTextPlugin object displays a plain or rich text attribute in an NSText object (com.apple.cocoa.application.NSText) 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
NSText, NSTextView.


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.
enabled A boolean attribute of the selected object, which determines whether the text object is enabled.


Object Keys Taken
delegate An EOTextAssociation accepts delegate messages related to the editing and validation of text; see the NSText and NSTextView class specifications for more information.

Constructors



EOCocoaTextPlugin

public EOCocoaTextPlugin( com.webobjects.eointerface.EOWidgetAssociation anEOWidgetAssociation, Object widget)

Creates a new EOCocoaTextPlugin to monitor and update the value in aDisplayObject, which is typically aCocoa NSActionCell.

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.
