Field Value
Examples
// Initialize a selection changed listener.
// The target selection is reflected in the client.
Automation.AddAutomationEventHandler(
TextPattern.TextSelectionChangedEvent,
targetDocument,
TreeScope.Element,
OnTextSelectionChange);
' Initialize a selection changed listener.
' The target selection is reflected in the client.
Dim onSelectionChanged As AutomationEventHandler = _
New AutomationEventHandler(AddressOf OnTextSelectionChange)
Automation.AddAutomationEventHandler( _
TextPattern.TextSelectionChangedEvent, targetDocument, _
TreeScope.Element, onSelectionChanged)
Remarks
Some text controls handle the text insertion point (cursor) as a zero-width text selection and might raise TextSelectionChangedEvent
when the cursor is moved.
Note
To follow cursor movements, UI Automation clients are advised to keep track of insertion point changes by listening for corresponding UI Automation element events rather than depending on TextSelectionChangedEvent.
This identifier is used by UI Automation client applications UI Automation providers should use the equivalent field in TextPatternIdentifiers.
