Hi,
How do i add characters in an NSAttributedString that will produce NSControlGlyphs, so that the boundingBoxForControlGlyphAtIndex:forTextContainer:proposedLineFragment:glyphPosition:characterIndex: method in NSATSTypesetter is called?

Thanks in advance for your answer

I think something as simple as @"abc\tdef" will do it - from the way I understand things, NSControlGlyph is generated for anything whose spacing needs to be determined programatically (as opposed to simple glpyhs that advance sequentially or things like diacritics that are overstruck on the last glpyh). The "\t", however, has a variable advancement width, depending on the location of the glpyh (so for NSControlGlyph case you need to look at the underlying charcter - in this case the tab - to be able to figure out how to handle it).
