Module Name:
|
||
|
- InteractivityAutomationPeer.h
|
||
|
|
||
|
Abstract:
|
||
|
- This module provides UI Automation access to the ControlInteractivity,
|
||
|
to support both automation tests and accessibility (screen
|
||
|
reading) applications.
|
||
|
- See TermControlAutomationPeer for more details on how UIA is implemented.
|
||
|
- This is the primary implementation of the ITextProvider interface, for the
|
||
|
TermControlAutomationPeer. The TermControlAutomationPeer will be attached to
|
||
|
the actual UI tree, via FrameworkElementAutomationPeer. However, the
|
||
|
ControlInteractivity is totally oblivious to the UI tree that might be hosting
|
||
|
it. So this class implements the actual text pattern for the buffer, because
|
||
|
it has access to the buffer. TermControlAutomationPeer can then call the
|
||
|
methods on this class to expose the implementation in the actual UI tree.
