Doug: added definitions of roll and rotation
Doug> added definitions of roll and rotation
Travis: so MouseWheel is the legacy event
Doug: there are several different mousewheel events; mouseWheel &
DOMMouseScroll
... so new event is created: Wheel
... but still define the legacy MouseWheel
Travis: could add some diagram
<scribe> ACTION: Doug to add a diagram about wheel axes etc

<trackbot> Created ACTION-6 - Add a diagram about wheel axes etc [on
Doug Schepers - due 2008-06-25].
smaug: problem is that systems produce events with line scroll delta
and pixel delta

smaug: scroll event happens after scrolling
Doug: HTML and CSS should define that if element is capable to
scroll, scroll should bubble to document
smaug: the default handling shouldn't bubble to document
<arve> [not participating, but following by accident] make sure that
the delta is well-defined both in terms of value and direction,
browser deviate on both, some send +1 where others send -60
Travis: wondering about the 2nd paragraph of 1.3
checkboxes and radiobuttons are special cases
<shepazu> arve, will do
<arve> shepazu: my highly personal proposal is to define an angle
and a distance
<scribe> ACTION: Doug to clarify default actions (section 1.3)

<trackbot> Created ACTION-7 - Clarify default actions (section 1.3)
[on Doug Schepers - due 2008-06-25].

Doug: many things should be defined by the host language
... Both HTML and SVG should define click event handling on a link -
event bubbles, default action is to fire DOMAction ...
... back to mousewheel
... arve had idea about angle
... Who should default the default handling of wheel event?
smaug: the default handling depends on ctrl, alt keys etc
Doug: I'll put a note that host language should define the default
action for the wheel event
<shepazu> angle could be derived from the distance of deltaX and
deltaY
Doug: how often would you actually need angle?
smaug: wheelevent should expose the type of the scroll units
Travis: wheelevent should use some common units
Doug: need to discuss about wheel event on the list
Travis: should the default action of wheel fire scroll or cause
scroll ?
smaug: cause scroll
which may cause scroll event
Doug: one can change the default handling of mouse wheel on system;
how many lines are scrolled
... should we actually have wheel event with its own units, like
pixels

Doug: host language defines how to react to rolls
... roll is abstract unit
