RE: Viewmode related issues

Hi Magnus,

Thanks for your comments and apologies for my delayed response.

Ad 1.
I am working on the summary of the properties that define the semantics of the media feature values (I shall sent a follow-up email to [1]).

What do you mean by "UA controls the layout of the widget desktop"?
UA specifies the available viewport, the rest is controlled by CSS in general.
Size is the size of the viewport.  It seem I need to state that in the VMMF.

Ad 2.
The view modes interfaces spec is here:
http://dev.w3.org/2006/waf/widgets-vm/vm-interfaces.src.html
It is still pre-FPWD ED.
>> I don't see any methods for changing the view-mode from within the widget
At present none of the methods is defined.
What about having "viewmode" attribute on TWI [2] that upon setting would change the mode?
This would work similarly to [3], I think.

>>Also I think it's important to get an event when the user agent has changed view-mode and/or width/height of
>>an widget but maybe that is also coming in a later version?
This is already captured in [4].

Ad 3.
I think this is in the scope of TWI.

Thanks,
Marcin

Subject: Viewmode related issues


For the agenda discussion...

1. Widget view modes (http://dev.w3.org/2006/waf/widgets-vmmf/). In section 3.2 "Presentation properties" it says the default view-mode of 'floating' is sized controlled by the widget. Is this correct? To me the size control for 'floating' should be the same as for 'application', i.e. "dependent on widget or user agent, the actual width and height may be overidden by the user agent". Since the user agent controls the layout of the widget desktop it also must be able to ultimately control the sizing of the widgets, right? Othervise, what should it do with a widget not fitting to a specific layout, not display it at all? Maybe this is described somewhere and I just didn't see it...

2. Widgets API (http://dev.w3.org/2006/waf/widgets-api/). I don't see any methods for changing the view-mode from within the widget (requirement 37, http://www.w3.org/TR/2009/WD-widgets-reqs-20090430/#display-mode-api-and-events<http://www.w3.org/TR/2009/WD-widgets-reqs-20090430/>). Is it there without me finding it or will it come in a later version (or has it been removed as requirement)? I hope it is there (or will come) because for many use cases it's essential to move to/from full-screen display programatically. Also I think it's important to get an event when the user agent has changed view-mode and/or width/height of an widget but maybe that is also coming in a later version?

3. It would be very nice to be able to write a widget desktop in SVG (or in HTML if someone would consider that ;-). To enable this it must be a way to access a Widget API from the HTML/SVG JS context and to have position, size, viewmode control through this API. Is this something that is considered by the WG?
