Seems to me you're focusing on the wrong aspect of the problem. The key to this is to track given words' positions as the text is scrolled/reflowed. If you lay out the text yourself (using NSLayoutManager, for example) this is not hard, but if you leave it to something else, such as NSTextView, it may be a lot harder (though NSTextView has a NSLayoutManager of which you can ask questions). Drawing the lines once you have those positions is relatively easy - NSBezierPaths will work, and are probably the simplest. --Graham _______________________________________________ Cocoa-dev mailing list ([email protected]) Please do not post admin requests or moderator comments to the list.
