How do I embed a child view within an NSTextView?

Question

I have a text view, in which I would like to place other views, like so:

=====================================
= This is an editable NSTextView... =
= /-------\                         =
= |Subview|                         =
= \-------/                         =
= other text.                       =
=====================================

There are NSTextAttachment s, but they seem to only be well-suited for images. How can I insert into the text a fully-functional NSView with keyboard/mouse interaction and subviews itself, etc?

Answer 1

You might want to check out the NSTextContainer and NSLayoutManager classes:

' NSTextContainer defines rectangular regions, but you can create subclasses that define regions of other shapes, such as circular regions, regions with holes in them, or regions that flow alongside graphics. '

' An NSLayoutManager uses NSTextContainer to determine where to break lines, lay out portions of text, and so on. '

The Cocoa Text Architecture Guide might be handy as well.
