CReversalTransition Class

Encapsulates a reversal transition.

Syntax

class CReversalTransition : public CBaseTransition;

Members

Public Constructors

Name Description
CReversalTransition::CReversalTransition Constructs a reversal transition object and initializes its duration.

Public Methods

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

Public Data Members

Name Description
CReversalTransition::m_duration The duration of the transition.

Remarks

A reversal transition smoothly changes direction over a given duration. The final value will be the same as the initial value and the final velocity will be the negative of the initial velocity. 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.

CReversalTransition::Create

Calls the transition library to create encapsulated transition COM object.

virtual BOOL Create(
    IUIAnimationTransitionLibrary* pLibrary,
    IUIAnimationTransitionFactory* \*not used*\);

Parameters

pLibrary
A pointer to transition library, which is responsible for creation of standard transitions.

Return Value

TRUE if transition is created successfully; otherwise FALSE.

CReversalTransition::CReversalTransition

Constructs a reversal transition object and initializes its duration.

CReversalTransition(UI_ANIMATION_SECONDS duration);

Parameters

duration
The duration of the transition.

CReversalTransition::m_duration

The duration of the transition.

UI_ANIMATION_SECONDS m_duration;
