public enum AccessibleEventType
Members| Member | Description |
|---|---|
| EVENT_SYSTEM_SOUND |
Sent when a sound is played. Currently nothing is generating this, we
are going to be cleaning up the SOUNDSENTRY feature in the control panel
and will use this at that time. Applications implementing WinEvents
are perfectly welcome to use it. Clients of IAccessible* will simply
turn around and get back a non-visual object that describes the sound.
|
| EVENT_SYSTEM_ALERT |
Sent when an alert needs to be given to the user. MessageBoxes generate
alerts for example.
|
| EVENT_SYSTEM_FOREGROUND |
Sent when the foreground (active) window changes, even if it is changing
to another window in the same thread as the previous one.
|
| EVENT_SYSTEM_MENUSTART |
Sent when entering into and leaving from menu mode (system, app bar, and
track popups).

Sent when entering into and leaving from menu mode (system, app bar, and
track popups).
|
| EVENT_SYSTEM_MENUPOPUPSTART |

that for a call to TrackPopupMenu(), a client will see EVENT_SYSTEM_MENUSTART

being shown.
|
| EVENT_SYSTEM_MENUPOPUPEND |
Sent when a menu popup comes up and just before it is taken down. Note

to apps and OLE to generate this, since the system doesn't know. Like
