IDirectManipulationCompositor interface (directmanipulation.h)

Represents a compositor object that associates manipulated content with a drawing surface, such as canvas (Windows app using JavaScript) or Canvas (Windows Store app using C++, C#, or Visual Basic).

Inheritance

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

Methods

The IDirectManipulationCompositor interface has these methods.

IDirectManipulationCompositor::AddContent Associates content (owned by the caller) with the compositor, assigns a composition device to the content, and specifies the position of the content in the composition tree relative to other composition visuals.
IDirectManipulationCompositor::Flush Commits all pending updates in the compositor to the system for rendering.
IDirectManipulationCompositor::RemoveContent Removes content from the compositor.
IDirectManipulationCompositor::SetUpdateManager Sets the update manager used to send compositor updates to Direct Manipulation.

Remarks

The content of a Direct Manipulation viewport must be manually updated during an input event for custom implementations of IDirectManipulationCompositor. Call Update to redraw the content within the viewport.

You specify manual mode on a viewport by calling either of these functions:

• SetViewportOptions, with DIRECTMANIPULATION_VIEWPORT_OPTIONS_MANUALUPDATE specified.
• SetUpdateMode, with DIRECTMANIPULATION_INPUT_MODE_MANUAL specified.
