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:
Methods
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. |
Remarks
The system provides an implementation of IDirectManipulationContent.
