What you want is possible, but likely difficult. First, you need to thoroughly understand the Cocoa text architecture and layout. From this alone, you would have known that subclassing NSTextView is likely the wrong approach. You will also need to see the WWDC 2010 talk on advanced text techniques. That will give you an idea about inline views. An all-Cocoa solution might not be the best choice, however, although it will probably be easier (though you won't think so as you trudge through it, take it from me ;-), though likely less performant. You may quickly get into having too many NSViews, which are heavy and slow. Anyway, you would likely start with an NSView subclass, using multiple NSTextViews when text is divided by a "block" view, and inline views for the inline part. You will also likely want to become familiar with NSTextBlock, which will make having text flow around an object much easier. HTH, Keary Suska Esoteritech, Inc.
