Direct Manipulation Interfaces

The topics contained in this section provide the reference specifications for Direct Manipulation interfaces.

Note

When implementing a Direct Manipulation object, ensure that the IUnknown implementation supports multithreading through thread-safe reference counting. For more information, see InterlockedIncrement and InterlockedDecrement.

Topic	Description
IDirectManipulationAutoScrollBehavior	Represents the auto-scroll animation behavior of content as it approaches the boundary of a given axis or axes.
IDirectManipulationCompositor	Represents a compositor object that associates manipulated content with a drawing surface, such as canvas.
IDirectManipulationCompositor2	Represents a compositor object that associates manipulated content with drawing surfaces across multiple processes.
IDirectManipulationContent	Encapsulates content inside a viewport, where content represents a visual surface clipped inside the viewport.
IDirectManipulationDeferContactService	Represents a service for managing associations between a contact and a viewport.
IDirectManipulationDragDropBehavior	Represents behaviors for drag and drop interactions, which are triggered by cross-slide or press-and-hold gestures.
IDirectManipulationDragDropEventHandler	Defines methods to handle drag-drop behavior events.
IDirectManipulationFrameInfoProvider	Represents a time-keeping object that measures the latency of the composition infrastructure used by the application and provides this data to Direct Manipulation.
IDirectManipulationInteractionEventHandler	Defines methods to handle interactions when they are detected.
IDirectManipulationManager	Provides access to all the Direct Manipulation features and APIs available to the client application.
IDirectManipulationManager2	Extends the IDirectManipulationManager interface that provides access to all the Direct Manipulation features and APIs available to the client application.
IDirectManipulationManager3	Extends the IDirectManipulationManager2 interface that provides access to all the Direct Manipulation features and APIs available to the client application.
IDirectManipulationPrimaryContent	Encapsulates the primary content inside a viewport.
IDirectManipulationUpdateHandler	Defines methods for handling manipulation update events.
IDirectManipulationUpdateManager	Manages how compositor updates are sent to Direct Manipulation.
IDirectManipulationViewport	Defines a region within a window (referred to as a viewport) that is able to receive and process input from user interactions.
IDirectManipulationViewport2	Provides management of behaviors on a viewport. A behavior affects the functionality of a particular part of the Direct Manipulation workflow.
IDirectManipulationViewportEventHandler	Defines methods for handling status and update events for the viewport.
