I don't believe there's a conflict here, but I will have to think about it more. In the "default" mode, focus and mouse events are conventionally independent, so the author's redundancy shouldn't pose a problem. In the enhanced mode required by the UAAG 1.0 -- keyboard access even to mouse handlers -- nothing suggests that an implementation would necessarily trigger a handler twice unless on explicit user request. - Ian > replies will be used in the following document: > Script Techniques for Web Content Accessibility Guidelines 2.0 > http://www.learningdifficulty.org/develop/w3c-scripts.html#onfocus > this is currently a non-wcag draft > > Jim lye wrote to GL: > ....I'm concerned with the confusion and incompatibility this could bring, > in > the WAI User Agent guidelines, the onmouseover etc. events must be made > available to keyboard users, therefore, if you duplicate focus and > mouseover - you have the situation where users will see two actions, > which could confuse, or equally cause scripting problems. > > Please excuse cross posting I've not had a response yet from GL. > and thanks. > > jonathan chetwynd > IT teacher (LDD) > j.chetwynd@btinternet.com > http://www.peepo.com "The first and still the best picture directory > on the web" -- Ian Jacobs (ij@w3.org) http://www.w3.org/People/Jacobs Tel: +1 718 260-9447
