[SOLVED] Re: What is [NSTextStorage fontSetChanged]?

I don't understand yet what is [NSTextStorage fontSetChanged] exactly.

But I found a workaround for my problem that the document edited flag 
is set by the fontSetChanged notification while nothing was edited in 
the document.

I added the following override method to my custom NSTextStorage 
subclass.
- (BOOL)fixesAttributesLazily

{ return YES; }

By default, custom NSTextStorage subclasses are not lazy, but the 
provided concrete subclass is lazy by default.
