CLinearTransition Class

  • Article

Encapsulates a linear transition.

Syntax

class CLinearTransition : public CBaseTransition;

Members

Public Constructors

Name Description
CLinearTransition::CLinearTransition Constructs a linear transition object and initializes it with duration and final value.

Public Methods

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

Public Data Members

Name Description
CLinearTransition::m_dblFinalValue The value of the animation variable at the end of the transition.
CLinearTransition::m_duration The duration of the transition.

Remarks

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.

CLinearTransition::CLinearTransition

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.

CLinearTransition::Create

Calls the transition library to create encapsulated transition COM object.

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

Parameters

pLibrary
A pointer to an IUIAnimationTransitionLibrary interface, which defines a library of standard transitions.

Return Value

TRUE if transition is created successfully; otherwise FALSE.

CLinearTransition::m_dblFinalValue

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

DOUBLE m_dblFinalValue;

CLinearTransition::m_duration

The duration of the transition.

UI_ANIMATION_SECONDS m_duration;
