Encapsulates a linear transition.

class CLinearTransition : public CBaseTransition;  

Public Constructors

NameDescription
CLinearTransition::CLinearTransitionConstructs a linear transition object and initializes it with duration and final value.

Public Methods

NameDescription
CLinearTransition::CreateCalls the transition library to create encapsulated transition COM object. (Overrides CBaseTransition::Create.)

Public Data Members

NameDescription
CLinearTransition::m_dblFinalValueThe value of the animation variable at the end of the transition.
CLinearTransition::m_durationThe duration of the transition.

During a linear transition, the value of the animation variable transitions linearly from its initial value to a 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.

Header: afxanimationcontroller.h

Constructs a linear transition object and initializes it with duration and final value.

CLinearTransition(
    UI_ANIMATION_SECONDS duration,  
    DOUBLE dblFinalValue);

Parameters

duration
The duration of the transition.

dblFinalValue
The value of the animation variable at the end of the transition.

Calls the transition library to create encapsulated transition COM object.

virtual BOOL Create(
    IUIAnimationTransitionLibrary* pLibrary,  
    IUIAnimationTransitionFactory* */);

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.

The value of the animation variable at the end of the transition.

DOUBLE m_dblFinalValue;  

The duration of the transition.

UI_ANIMATION_SECONDS m_duration;
