IKeyboardInputSite Interface


Manages keyboard focus within the container. This interface implements keyboard message management in WPF-Win32 interoperation scenarios.

public interface class IKeyboardInputSite

Public Interface IKeyboardInputSite


A container should provide a unique instance of this interface for each of its contained components.

The IKeyboardInputSite interface and the IKeyboardInputSink are used together to provide support for keyboard actions across interoperation boundaries. A site (IKeyboardInputSite implementation) represents a parent of a sink (IKeyboardInputSink). The sink (IKeyboardInputSink) implements the majority of keyboard behavior. Each site must also provide a sink, because the site-specific sink is returned by a property of the IKeyboardInputSite interface.

For a discussion of the input architecture specifically implemented for Windows Forms interoperation, see Windows Forms and WPF Interoperability Input Architecture.

For more information about WPF-Win32 interoperation scenarios, see WPF and Win32 Interoperation.
