NSLinkAttributeName and re-layout

Subject: NSLinkAttributeName and re-layout

My NSTextView subclass is adding and removing the NSLinkAttributeName attribute on various ranges of text. Although there is no visible effect (because the linkTextAttributes dictionary is empty), such changes are causing re-layout, with unacceptable effects on performance.

It would be very nice if the layout manager supported a functional equivalent of NSLinkAttributeName as a temporary attribute, or if the text storage were smart enough to recognize cases where an attribute change does not require re-layout. I may file an enhancement request along those lines. But in the meantime, can somebody suggest a reasonable way for me to prevent re-layout when I am making an attribute change that I know does not require it?

I am targeting the 10.2.8 API, but the issue affects me only in 10.4 (I'm using a different approach in 10.[1-3] that performs very well, but an NSTextView behavior change in 10.4 renders it untenable). _______________________________________________ Do not post admin requests to the list.
