Hi,

one of the ways could be to use own NSLayoutManager and use it to draw 
NSAttributed string
in my subclass of NSTextAttachmentCell and its draw method.
NSLayoutManager has boundingRectForGlyphRange:inTextContainer: method from 
which I could obtain bounds of glyph representing 
NSTextAttachment at position I am interested in.
I can use this method to get rectangles of all attachments in my 
updateTrackingAreas method.

Does anybody see this as the right way ?

Peter
