[g-a-devel]Implementing ATK on Custom Widgets

[Marc Mulcahy <marc mulcahy sun com>]

Hi All,

Still attempting to get libzvt accessibility support running.  We need to 
make a decision as to how and what parts of gail should be exposed.  I've 
run into an issue with the technique used to provide accessibility for 
gtkhtml2-- namely that the accessibility implementation class can't have 
any data of its own.  This won't work for libzvt, since it *has* to keep 
some callback pointers laying around.  I could attach a private data 
structure to the accessible object using a quark or some such horrid and 
ugly thing, but this seems to break the GNOME standard of straightforward code.

I propose that at least we expose GailWidget, so that accessibility 
implementations for custom widgets don't have to re-invent the wheel for 
the basic functions like name, description, screen geometry etc.

Thoughts?

Marc
