Protected Methods

Name	Description
CAnimationController::CleanUpGroup	Overloaded. A helper that cleans up the group.
CAnimationController::OnAfterSchedule	Called by the framework when an animation for the specified group has just been scheduled.

Protected Data Members

Name	Description
CAnimationController::g_KeyframeStoryboardStart	A keyframe that represents start of storyboard.
CAnimationController::m_bIsValid	Specifies whether an animation controller is valid or not. This member is set to FALSE if current OS does not support Windows Animation API.
CAnimationController::m_lstAnimationGroups	A list of animation groups that belong to this animation controller.
CAnimationController::m_pAnimationManager	Stores a pointer to Animation Manager COM object.
CAnimationController::m_pAnimationTimer	Stores a pointer to Animation Timer COM object.
CAnimationController::m_pRelatedWnd	A pointer to a related CWnd object, which can be automatically redrawn when the status of animation manager has changed, or post update event has occurred. Can be NULL.
CAnimationController::m_pTransitionFactory	Stores a pointer to Transition Factory COM object.
CAnimationController::m_pTransitionLibrary	Stores a pointer to Transition Library COM object.

Remarks

The CAnimationController class is the key class that manages animations. You may create one or more instances of animation controller in an application and, optionally, connect an instance of animation controller to a CWnd object using CAnimationController::SetRelatedWnd. This connection is required to send WM_PAINT messages to the related window automatically when animation manager status has changed or animation timer has been updated. If you do not enable this relation, you must redraw a window that displays an animation manually. For this purpose you can derive a class from CAnimationController and override OnAnimationManagerStatusChanged and/or OnAnimationTimerPostUpdate and invalidate one or more windows when necessary.
