GenericRootAutomationPeer Class

Exposes HwndSource types to UI Automation.

Namespace: System.Windows.Automation.Peers
Assembly: PresentationCore (in presentationcore.dll)

public class GenericRootAutomationPeer : UIElementAutomationPeer
public class GenericRootAutomationPeer extends UIElementAutomationPeer
public class GenericRootAutomationPeer extends UIElementAutomationPeer
You cannot use this managed class in XAML.

GenericRootAutomationPeer is used as a peer for HwndSource when it contains the following tree:

Because only UIElement types have peers, and visuals are not UIElement types, a common parent does not exist in the UI Automation tree for the UIElement types. UI Automation expects a single root peer from the application; therefore, Microsoft .NET Framework version 3.0 creates a GenericRootAutomationPeer for the HwndSource in order to serve as a single root peer to parent peers for the two UIElement types.

Typically, the root peer is a WindowAutomationPeer.

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
