Re: [g-a-devel]Making GnomeIconList accessible

[Marc Mulcahy <marc mulcahy sun com>]

Hi Federico,

I looked at this some time ago, and attempted to partially solve it by 
implementing libgnomecanvas support, which turned out not to be the right 
answer...

My enalysis was that an AtkObject implemented on behalf of GnomeIconList 
(AccessibleIconList) would implement two interfaces, AtkComponent and 
AtkSelection.  It can inherit the AtkComponent interface from GailWidget 
(see examples in libzvt and gtkhtml2 head).  It could implement 
AtkSelection relatively easily, GnomeIconList seemed to contain all the 
necessary API to get the relevant information.

The libgnomecanvas support which I implemented exposes all the items 
contained on the GnomeCanvas of the icon list-- I.E. two for each icon (the 
text and the pixbuf).  (actually I don't think the icon list uses 
GnomeCanvasText anymore, so, one of the two children of each icon is 
probably an unknown object from an accessibility perspective)

So, I think the right answer is to provide implementations for 
get_n_children and ref_accessible_child for AccessibleIconList.

\A second AtkObject would need to be implemented on behalf of the icons 
themselves (the children of GnomeIconList).  It was my assessment that this 
AtkObject would have to implement AtkText and AtkImage.
