DS: I had two actions
Mouse Wheel

<shepazu> ACTION-252: Send mousewheel proposal to list
<shepazu> [13]http://www.w3.org/2008/webapps/wiki/Mousewheel
[13] http://www.w3.org/2008/webapps/wiki/Mousewheel
DS: I added proposal to the wiki
... Olli, have you reviewed this yet?
OP: No, not yet
DS: (describes proposal)
... Single event has all wheelDelta information
... The default value for wheelDelta wil always be the larger of x
or y or z
... A flaw in this plan - wheelDelta may not be available
in Firefox
OP: Firefox has mousescrollevent
DS: Do you have issues with using a new event?
OP: There will be regressions, that is a problem
... Perhaps event Google Maps, for exmaple
DS: Will be a problem for some deployed web applications
... I wonder if we can have feedback from Google maps about this
... Perhaps we can come up with a way - suggest scripts
non-normatively for work arounds
... Easy? Check if mousewheelevent interface exists, use that
instead
OP: Yes, it may still break some sites
DS: YEs, any change will break sites
... Goal is to have least amount of breaks
OP: In Firefox we have stopped support for some features, there are
warning messages that some features are depricated and then removed
... Some very old NS 4 stuff
DS: Mose user of mouse whell are fairly modern cases
... IN that case, these are the ones probably still live and can
change to adapt
... If you find there is a way you can 'alias' domwheelscroll that
would be very interesting
... The wheelDelta is unitless - there is no range of particular
numbers
OP: Somebody was trying to implement pixel scrolling, pixel quite
different than normal wheelDelta values
<smaug> [14]https://bugzilla.mozilla.org/show_bug.cgi?id=350471
[14] https://bugzilla.mozilla.org/show_bug.cgi?id=350471
DS: I wonder if the term click is wrong here
... There is mouse click then delta - could be confused
... You can also click a mouse wheel
AE: Makes sense to try and find something different
DS: I think we MS in on this, they were the ones who wanted to unify
it into one mouse event
<scribe> ACTION: Doug to review Mozilla bug for pixel scrolling and
consider wrt mousewheel proposal [recorded in
[15]http://www.w3.org/2008/03/12-webapi-minutes.html#action01]
<trackbot> Created ACTION-258 - Review Mozilla bug for pixel
scrolling and consider wrt mousewheel proposal [on Doug Schepers -
due 2008-03-19].
<scribe> ACTION: Doug to give deadline for next week regarding mouse
wheel [recorded in
[16]http://www.w3.org/2008/03/12-webapi-minutes.html#action02]
<trackbot> Created ACTION-259 - Give deadline for next week
regarding mouse wheel [on Doug Schepers - due 2008-03-19].
Key Event Order
DS: Regarding mousewheel, Ollie are there more comments
OP: If the mousewheelevent is cancelled, only vertical is cancelled.
Why only vertical?
DS: That is for mouseomniwheel event
... Someone may want to cancel default action just for x or y or z
... My proposal is if person wants to do that, they cancel the even
and generate a new one with just wheel delta values that they want
... Does this differ from DOMScrollWheel significantly?
... Would you mind reviewing it?
OP: Yes, sure
DS: My hope is that it is a superset of the Firefox equivalent
... I think we use detail
OP: Called DOMMouseScroll
<scribe> ACTION: Doug to review DOMMouseScroll wrt mousewheel
proposal [recorded in
[17]http://www.w3.org/2008/03/12-webapi-minutes.html#action03]
<trackbot> Created ACTION-260 - Review DOMMouseScroll wrt mousewheel
proposal [on Doug Schepers - due 2008-03-19].
<shepazu> [18]http://www.w3.org/2005/06/tracker/webapi/actions/251
[18] http://www.w3.org/2005/06/tracker/webapi/actions/251
<shepazu> ACTION-251: Provide Andrew with model wording for key
evnts sequence
<shepazu> [19]http://www.w3.org/2008/webapps/wiki/Key_event_order
[19] http://www.w3.org/2008/webapps/wiki/Key_event_order
DS: This is my proposal
... Not solid yet
... Misses out on - when textInput is really done and relationship
to IME ( input method editor)
... Oliver Hunt seemed to think it was more complicated, working
with IME, than I feared
... Will defined keypress
... But is optional
... I thought the wording we use for key order is a SHOULD and
fallback for MAY where there are system where it differs
... This SHOULD be the key event order and if this is not the key
event order of the native system then the implementation should
provide an abstraction layer but an implementation MAY give the
events in the order that the environment generates
... Fairly strong while still allowing flexibility
... Should give authors a fairly consistent interface
AE: Sounds reasonable
OP: I do not like SHOULDs or MAYs
DS: Yes, there are circumstances where it's hard to avoid
<scribe> ACTION: Doug to test to see if there is an order to keydown
and keypress [recorded in
[20]http://www.w3.org/2008/03/12-webapi-minutes.html#action04]
<trackbot> Created ACTION-261 - Test to see if there is an order to
keydown and keypress [on Doug Schepers - due 2008-03-19].
OP: Keydown is always before keypress
AE: For browsers presumably it's doable to have a consistent key
sequence across platforms ( DOM events are not system event )
... The sequence may be issue for mobile/embedded like TV remote
controls, etc
DS: If the device permits, implementers must implement the key order
in the follwing sequence.
In the case where the platform generates events in a different
order, implementations should provide an abstraction layer
to emulate the sequence above.
The UA MAY send the events to the user in a different order if they
are constrained but this is strongly discouraged due to difficulty
in authoring content
DS: If we are confident keydown is not repeated, we can take it out
OP: ( reads off various test results from various platforms for key
sequence )
<scribe> ACTION: Doug to create illustration of key sequence as a
tree diagram [recorded in
[21]http://www.w3.org/2008/03/12-webapi-minutes.html#action05]
<trackbot> Created ACTION-262 - Create illustration of key sequence
as a tree diagram [on Doug Schepers - due 2008-03-19].
AE: Key flow diagram?
DS: Next meeting we will try and resolve mousewheel
AE: Perhaps I will add a coupe of actions that I inherited
