Enumeration Type Documentation

enum IA2Actions

This enum defines values which are predefined actions for use when implementing support for media.

This enum is used when specifying an action for IAccessibleAction::doAction.

Enumerator
IA2_ACTION_OPEN	Used to inform the server that the client will signal via IA2_ACTION_COMPLETE when it has consumed the content provided by the object. This action allows the object's server to wait for all clients to signal their readiness for additional content. Any form of content generation that requires synchronization with an AT would require use of this action. One example is the generation of text describing visual content not obvious from a video's sound track. In this scenario the Text to Speech or Braille output may take more time than the related length of silence in the video's sound track.
IA2_ACTION_COMPLETE	Used by the client to inform the server that it has consumed the most recent content provided by this object.
IA2_ACTION_CLOSE	Used to inform the server that the client no longer requires synchronization.
