[Adobe-source-devel] Re: asl-users: Request for Comments: ASL Picture Widget

[Sean P. <sp...@ad...>]

The semantic description is a bit at odds with itself and with the API -

First - what is this? If it is a visual label (like a static_text) -  
then the API is pretty good except there shouldn't be a "hit proc" -  
there should _never_ be a hit proc. This is either a label (a purely  
visual element like a static text) - a button, or a view. Not one  
picture to rule them all. If this is to be only a label, perhaps it  
should be combined with static_text under a new "label" widget - the  
binding to the image through Eve might be an href in the label (hmmm,  
maybe that's over kill) - and an alternate constructor on the label_t  
widget.

If it is a button - mostly the same comments as above except it  
should be part of button_t.

If it is an image view (this would be the most ambitious widget) -  
then it should bind to an image view. The widget should support at  
least pan and zoom (these controls wouldn't need to be bind-able -  
but allow them to be bound would let you attach them to the basic  
sheet to preserve view state). I can envision all kinds of nice UI's  
for this (transparent overlay that comes up when you mouse over...) -  
could be slick - we can attempt to work with a UI designer to design  
the _last_ preview widget...

If there is a monitor function - that would imply an image editor...  
perhaps a bit too ambitious for the first cut.
