Members

Public Constructors

Name	Description
CLinearTransitionFromSpeed::CLinearTransitionFromSpeed	Constructs a linear-speed transition object and initializes it with speed and final value.

Public Methods

Name	Description
CLinearTransitionFromSpeed::Create	Calls the transition library to create encapsulated transition COM object. (Overrides CBaseTransition::Create.)

Public Data Members

Name	Description
CLinearTransitionFromSpeed::m_dblFinalValue	The value of the animation variable at the end of the transition.
CLinearTransitionFromSpeed::m_dblSpeed	The absolute value of the variable's velocity.

Remarks

During a linear-speed transition, the value of the animation variable changes at a specified rate. The duration of the transition is determined by the difference between the initial value and the specified final value. Because all transitions are cleared automatically, it's recommended to allocated them using operator new. The encapsulated IUIAnimationTransition COM object is created by CAnimationController::AnimateGroup, until then it's NULL. Changing member variables after creation of this COM object has no effect.
