This might help; forgive me if it doesn't address your situation. In an NSTextStorage object, text attributes are values that apply to some range of text in the object. If the object has no text, then setting attributes is meaningless. If a textStorage length is 0, and you set a foreground color attribute, and subsequently add some text, the text does not necessarily show up with that foreground color. When plain text without attributes is added to a textStorage object--as, for example, with input from the keyboard--the NSTextView uses its typingAttributes dictionary to apply attributes to the new text. So, if you've got a new NSTextView whose NSTextStorage length is 0, and you are going to add some plain text to it, you must first set the typingAttributes of the NSTextView to the desired attributes. -setForegroundColor: is one of the scriptability methods of NSTextStorage. Those methods are not recommended for use in non-scripting situations. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
