Represents the method implemented by the UI Automation client application to handle the event raised by a UI Automation provider when the focus has changed.
public delegate void AutomationFocusChangedEventHandler(System::Object ^ sender, AutomationFocusChangedEventArgs ^ e);
public delegate void AutomationFocusChangedEventHandler(object sender, AutomationFocusChangedEventArgs e);
type AutomationFocusChangedEventHandler = delegate of obj * AutomationFocusChangedEventArgs -> unit
Public Delegate Sub AutomationFocusChangedEventHandler(sender As Object, e As AutomationFocusChangedEventArgs)
- sender
- Object
The object that raised the event.
Information about the event.
The following example implements a delegate to handle focus-changed events.
private void OnFocusChanged(object src, AutomationFocusChangedEventArgs e)
{
AutomationElement elementFocused = src as AutomationElement;
// TODO: Do something in response to the focus change.
}
Private Sub OnFocusChanged(ByVal src As Object, ByVal e As AutomationFocusChangedEventArgs)
Dim elementFocused As AutomationElement = DirectCast(src, AutomationElement)
' TODO: Do something in response to the focus change.
End Sub
Use an AutomationFocusChangedEventHandler delegate to define the method that is called by a client to handle UI Automation focus-changed events.
The AutomationElement represented by sender
might not have any cached properties or patterns, depending on whether the application subscribed to this event while a CacheRequest was active.
