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.

CLinearTransitionFromSpeed::CLinearTransitionFromSpeed
Constructs a linear-speed transition object and initializes it with speed and final value.
CLinearTransitionFromSpeed(
DOUBLE dblSpeed,
DOUBLE dblFinalValue);
Parameters
dblSpeed
The absolute value of the variable's velocity.
dblFinalValue
The value of the animation variable at the end of the transition.
CLinearTransitionFromSpeed::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.
CLinearTransitionFromSpeed::m_dblFinalValue
The value of the animation variable at the end of the transition.
DOUBLE m_dblFinalValue;
CLinearTransitionFromSpeed::m_dblSpeed
The absolute value of the variable's velocity.
DOUBLE m_dblSpeed;
