It’s applied by NSButtonCell, which knows that if it’s in the selected state and its image is marked as a template image (or some set of conditions like that), then it should apply the glow when drawing. I take it you’re trying to get this effect in some place other than inside a button? It’s not unreasonable to use an NSCell instance elsewhere— that’s essentially what cells are for, to abstract away some of the drawing behavior from the control view that uses them. I think NSButtonCell uses NSSetFocusRingStyle() to provide the actual effect, but there may be additional magic in there. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
