AutomationFocusChangedEventHandler Delegate

Definition

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.

C#
public delegate void AutomationFocusChangedEventHandler(object sender, AutomationFocusChangedEventArgs e);

Parameters

sender
Object

The object that raised the event.

e
AutomationFocusChangedEventArgs

Information about the event.

Examples

The following example implements a delegate to handle focus-changed events.

C#
private void OnFocusChanged(object src, AutomationFocusChangedEventArgs e)
{
    AutomationElement elementFocused = src as AutomationElement;
    // TODO: Do something in response to the focus change.
}

Remarks

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.
