face for some word in NSTextView, but could not find any solution.
Please describe me how to do this.
any help is much appriciated
NSTextView has a -textStorage method that returns a NSTextStorage
instance, which is a subclass of NSMutableAttributedString. The docs
for that class contain the answer to your question. Briefly, you need
to figure out the ranges of the characters that you want to apply the
font attributes to, then use the [textStorage
addAttribute:NSFontAttributeName value:theBoldFont
range:theCharacterRange] method to do it, or -applyFontTraits:range:,
depending on what you're doing.
Generally it's much easier to drive this using the Font Panel, which
NSTextView is already set up to handle. Just ensure that -
setUsesFontPanel: is called with YES.
