We have a proposal already for the CSS WG to review:
http://dev.w3.org/2006/waf/widgets-vm/vm-interfaces.src.html
It seems like this needs to align to the current CSS OM View spec:
<http://dev.w3.org/csswg/cssom-view/>
which has a StyleMedia interface available on the window object
as 'styleMedia', rather than 'media'.
I would expect to see events related to media type changes in the
CSS OM View spec too, rather than in a widgets-related spec.
I totally agree, there is much overlap. We should start looking at
how
to merge the two specs (or our requirements) into the CSS OM View
spec. I would be happy for the widgets one to vanish if the CSS OM
View spec would handled our use cases.
Perhaps we should have a joint teleconf or something to arrange
how to
proceed... I'll leave that up to the chairs, however.
To make Widget View Modes Interfaces [1] redundant, we would like to
propose extending CSSOM Views' matchMedium method to have a callback
as a second argument.
This would address the following sections of [1] in the following
ways:
# 3.2. Media Type Changed Event Types
styleMedia.matchMedium("screen", function() { alert("no
longer screen!") })
# 3.3. View Mode Changed Event Types
styleMedia.matchMedium("(viewmodesyntax)", ... )
# 3.4. Resolution Changed Event Types
styleMedia.matchMedium("(resolution:300dpi)", ... )
# 3.5. Orientation Changed Event Types
styleMedia.matchMedium("(orientation:landscape)", ... )
The proposal has it's origins on the Mozilla bug list (see comment
from David Baron):
https://bugzilla.mozilla.org/show_bug.cgi?id=542058#c3
This is overlapping with ViewModeChanged events:
<http://dev.w3.org/2006/waf/widgets-vm/vm-interfaces.src.html#viewmodechangedeventtypes
>
Do we really need both?
No, we don't need both. To be clear, we want to kill off vm-
interfaces.src.html in favor of CSSOM Views (as we have shown that it
does more or less what we need).
Kind regards,
Marcos
