NSTextAttachmentCell — Mac OS X 10.0

Synopsis

This protocol declares an interface for classes that draw text attachments and handle mouse events within a text attachment. NSCell implements all of the methods of this protocol, less three: cellBaselineOffset, setAttachment:, and attachment. NSTextAttachmentCell extends NSCell’s interface by implementing these three methods.
