It looks like WebKit HTML editing code has several concepts of a "canonical" position:
- Positions are not automatically canonicalized, but Position.isCandidate() and PositionIterator.isCandidate() pick out some of them as better ones. - VisiblePositions are automatically canonicalized with VisiblePosition::canonicalPosition(). A Position that corresponds to a VisiblePosition is called deepEquivalent. - To be used in ranges, Positions have to be canonicalized with rangeCompliantEquivalent(). Even VisiblePositions are not directly suitable for use in ranges. Can the differences between these be explained in some high-level fashion? So far, I haven't had much luck with understanding them from reading the code. - WBR, Alexey Proskuryakov. _______________________________________________ webkit-dev mailing list [email protected] http://lists.webkit.org/mailman/listinfo/webkit-dev
