IDirectManipulationUpdateManager interface

Manages how compositor updates are sent to Direct Manipulation.

This interface enables the compositor to trigger an update on Direct Manipulation whenever there is a compositor update. The application should not call the methods of this interface directly.

When to implement

The system provides an implementation of IDirectManipulationUpdateManager.

The application can get a pointer to the system-provided IDirectManipulationUpdateManager by calling GetUpdateManager. The application should set this pointer to the compositor using the SetUpdateManager method during Direct Manipulation initialization.

If you provide your own implementation, call Update to trigger an update on Direct Manipulation whenever there is a compositor update.
