[This is preliminary documentation and subject to change.]
The simple Accessible Event Watcher (Accevent.exe) application logs the following types of events as they occur within the system.
| Event Type | Event Name |
|---|---|
| Creation or Destruction | EVENT_OBJECT_CREATE, EVENT_OBJECT_DESTROY |
| Location | EVENT_OBJECT_REORDER, EVENT_OBJECT_PARENTCHANGE, EVENT_OBJECT_LOCATIONCHANGE |
| State | EVENT_OBJECT_STATECHANGE, EVENT_OBJECT_SHOW, EVENT_OBJECT_HIDE |
| Focus or Selection | EVENT_OBJECT_FOCUS, EVENT_OBJECT_SELECTION, EVENT_OBJECT_SELECTIONADD, EVENT_OBJECT_SELECTIONREMOVE, EVENT_OBJECT_SELECTIONWITHIN |
| Description | EVENT_OBJECT_NAMECHANGE, EVENT_OBJECT_VALUECHANGE, EVENT_OBJECT_DESCRIPTIONCHANGE |
| Other | EVENT_OBJECT_HELPCHANGE, EVENT_OBJECT_DEFACTIONCHANGE, and others |
| Caret | For caret object events |
| Cursor | For cursor object events |
| Mode | For modality events (like EVENT_SYSTEM_MOVESIZESTART, EVENT_SYSTEM_MOVESIZEEND, and others) |
Warning Do not use this sample while the OACSpy application is spying on event notifications. If both applications are active, they will log each other's events, generating events in the process. This causes an endless loop.
