By far the simplest approach here is going to be to make an image that contains a checkmark. Developers are discouraged from using low-level text attributes because it completely ignores all the important high-level stuff that goes in to making text look good. You're not really drawing text here. > However, Quartz seemingly makes the trivial very difficult. Why for > example, does this code not work?

CGFontGetGlyphWithGlyphName (and all of CGFont) deals in TrueType/AAT concepts, NOT Unicode concepts. Unicode does not even name glyphs; it names codepoints. The glyph names you provide to this function are the kind that would be found in the font's `post` table, not Unicode codepoint names. --Kyle Sluder _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
