Manfred,
I believe implementing a custom NSTextAttachmentCell can serve your
purpose. NSTextAttachment allows your to specify an arbitrary an
NSCell instance that conforms to the NSTextAttachmentCell protocol.
You can start exploring from http://developer.apple.com/documentation/
Cocoa/Conceptual/TextAttachments/index.html
Phil,
If you want text that flows around objects, you will need to use
more than one text view each with its own custom text container
that defines a bounding rectangle. Hooking up these multiple views
so that text editing done in one is reflected in the other ain't
easy. Read about the NSTextStorage and NSTextContainer classes.
You don't need to create multiple NSTextContainer/NSTextView to do
this. You can have a custom NSTextContainer that returns line
fragments flow around your layout objects. And, besides,
coordinating multiple NSTextContainer/NSTextView hooked to an
NSLayoutManager is automatic.

What you're asking for is not supported in any simple way by the
cocoa text system.

If you find an easy way to do it, let me know. I'd kill for
embedded images whose text flows.
An alternative might be to use a custom WebView. You could make it
editable and maybe (?) override some methods to support object
resizing and whatnot.

I would like to insert custom objects into an NSTextView. The
objects need to flow with the text, they need to be able to change
size and respond to clicks. How would I do that? I couldn't find
hints in the documentation on how to implement and neither any
sample code, so I would be glad if someone could point me to where
to start.
Thanks
Manfred
