IDirectManipulationContent interface (directmanipulation.h)

Encapsulates content inside a viewport, where content represents a visual surface clipped inside the viewport.

The content has a set of transforms that controls the visual movement of the surface during manipulation and inertia.

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.

Inheritance

The IDirectManipulationContent interface inherits from the IUnknown interface. IDirectManipulationContent also has these types of members:

The IDirectManipulationContent interface has these methods.


IDirectManipulationContent::GetContentRect Retrieves the bounding rectangle of the content, relative to the bounding rectangle of the viewport (if defined).
IDirectManipulationContent::GetContentTransform Retrieves the transform applied to the content.
IDirectManipulationContent::GetOutputTransform Gets the final transform applied to the content.
IDirectManipulationContent::GetTag Retrieves the tag object set on this content.
IDirectManipulationContent::GetViewport Retrieves the viewport that contains the content.
IDirectManipulationContent::SetContentRect Specifies the bounding rectangle of the content, relative to its viewport.
IDirectManipulationContent::SetTag Specifies the tag object for the content.
IDirectManipulationContent::SyncContentTransform Modifies the content transform while maintaining the output transform.

The system provides an implementation of IDirectManipulationContent.
