List of unsupported features

IAccessible methods that we don't currently support:

  • get_accHelp
  • get_accHelpTopic
  • put_accName
  • put_accValue
  • Visual Basic (IDispatch) bindings for IAccessible.
  • Directional navigation via accNavigate()
  • Scroll bars as IAccessible objects, although we do support EVENT_SCROLLINGEND when scrolling stops, ISimpleDOMNode::ScrollTo() and IA2 scrolling methods
  • STATE_MARQUEED. If that state is present it actually indicates "CHECKABLE" in Mozilla.
