I need to have a layout test register a callback with DRT, then have that
callback be called at the appropriate time (in order to test accessibility
notifications)
I can't figure out the right incantations to do so.
I'd like to do something like this in the LayoutTest
var addedNotification = liveRegion.addNotificationListener("ariaCallback");
then have a function in the test like
function ariaCallback(notification) {
// do stuff with notification
}
DRT knows when to call this method, but I'm not sure how.. This is what I have
so far, which does not work.
// The JavaScript callback we'll use when we get a notification
static JSStringRef AXNotificationFunctionCallback = 0;
static void _accessibilityNotificationCallback(id element, NSString*
notification)
{
if (!AXNotificationFunctionCallback)
return;
JSObjectRef function = JSObjectMakeFunction([mainFrame globalContext],
NULL, 0, NULL, AXNotificationFunctionCallback, NULL, 1, NULL);
JSValueRef argument = JSValueMakeString([mainFrame globalContext],
JSStringCreateWithCFString((CFStringRef)notification));
JSObjectCallAsFunction([mainFrame globalContext], function, NULL, 1,
&argument, NULL);
