You have to set the canvas accessible attribute to true for global
accessibility to work in Flash. It changes the way some things are
compiled, so it can't currently be set/unset at runtime.
View.aasilent is the way to silence specific views and their children
from being read by the screen reader...

I'm trying to implement some of the accessibility API (just
setAADescription) for DHTML, and am wondering
what is the API is for enabling and disabling accessibility, either
globally or on individual views/sprites.
Views have a setAccessible method that calls sprite.setAccessible, and
in swf that is implemented as
/** Turns accessibility on/off if accessible == true and a screen reader
is active
* @param Boolean accessible
*/
LzSprite.prototype.setAccessible = function(accessible) {
var a = LzBrowserKernel.isAAActive() && accessible;
//Debug.write('setAccessible', LzBrowserKernel.isAAActive(), a, this);
// turn off ugly _focusrect
_root._focusrect = 0;
_root.spriteroot.accessible = a;
}
What does this do? It seems like there's a global flag from
LzBrowserKernel, plus there's a canvas
'accessible' flag, right? Is this method only supposed to be called on
the canvas(sprite)? Or
is there supposed to be enable and disable for each view's 'accessible'
behavior?
