You might investigate an alternative (and much easier) solution. NSLayoutManager adopts the NSGlyphStorage protocol. That protocol declares a method, -layoutOptions, and one of the flags it can return is NSShowInvisibleGlyphs. Simply returning that flag may be all you need to do. In fact I think this is set for you when you call -setShowsInvisibleCharacters:YES I guess the difference is that it's all or nothing, which might be not the desired result. Another approach is to override -showCGGlyphs:positions:count:font:matrix:attributes:inContext: which is the primitive drawing method. All of the positioning and context flippedness has been handled by this point, so you can usually just go ahead and draw the characters. Inserting some other glyph at this point for the tab should be straightforward. --Graham _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
