That isn't possible since button is unsigned short. 79423 1 jrossi 2012-12-04 18:40:15 +0000 Here's my thinking on this issue: 1) Current PE spec text changes the values of button/buttons when firing pointer events 2) Current PE spec text does not change the values used when firing mouse events 3) DOM L3 Events defines button/buttons as an unsigned short 4) D3E implementations do not have interop* on how to handle the edge-case where you create a MouseEvent with a negative value for button. 4) (signed) short allows all the values required by D3E and also those by PE So my suggestion to resolve this issue is as follows: 1) Leave D3E spec as is. 2) Add to PE spec a partial MouseEvent interface that redefines button and buttons as short instead of unsigned short. 3) Include a note that PE's definition supersedes D3E and that implementations * Using this test code: var m = document.createEvent("MouseEvent"); m.initMouseEvent("mousedown", true,true,window,null,0,0,0,0,false,false,false,false, -1, null); console.log(m.button) Gecko: 65535 (wraps around), Webkit: 0 (snaps), IE9: -1 79424 2 bugs 2012-12-04 18:48:15 +0000 (In reply to comment #1) > 2) Add to PE spec a partial MouseEvent interface that redefines button and > buttons as short instead of unsigned short. As far as I know, you can't redefine property to be different type in partial interface. I'd be surprised if it is possible even in inheriting interface. Need to check what WebIDL says. 79426 3 jrossi 2012-12-04 18:57:19 +0000 The suggestion isn't that a partial interface can redefine another interface. I don't think WebIDL has a convention for one spec to override another. I think the only way to redefine an interface is via explicit spec text that says Pointer Events' definition supersedes DOM L3 Events' definition. The reason I suggested it be a partial interface is just because we only need to mention button and buttons. No need to completely redefine MouseEvent. 82252 4 jrossi 2013-01-29 03:23:09 +0000 Sent mail to WebApps to request this change be made to DOM L3 & UI Events. http://lists.w3.org/Archives/Public/www-dom/2013JanMar/0080.html 100459 5 travil 2014-02-13 01:01:00 +0000 Moving (with JRossi's permission) to DOM3 Events. 100566 6 travil 2014-02-13 22:57:19 +0000 Fixed just now in editor's draft: https://dvcs.w3.org/hg/dom3events/raw-file/tip/html/DOM3-Events.html unsigned short -> short in various places.
