Encapsulates a discrete transition.

Members
Public Constructors
| Name | Description |
|---|---|
| CDiscreteTransition::CDiscreteTransition | Constructs a discrete transition object and initializes its parameters. |
Public Methods
| Name | Description |
|---|---|
| CDiscreteTransition::Create | Calls the transition library to create encapsulated transition COM object. (Overrides CBaseTransition::Create.) |
Public Data Members
| Name | Description |
|---|---|
| CDiscreteTransition::m_dblFinalValue | The value of the animation variable at the end of the transition. |
| CDiscreteTransition::m_delay | The amount of time by which to delay the instantaneous switch to the final value. |
| CDiscreteTransition::m_hold | The amount of time by which to hold the variable at its final value. |
Remarks
During a discrete transition, the animation variable remains at the initial value for a specified delay time, then switches instantaneously to a specified final value and remains at that value for a given hold time. 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.

CDiscreteTransition::CDiscreteTransition
Constructs a discrete transition object and initializes its parameters.
CDiscreteTransition(
UI_ANIMATION_SECONDS delay,
DOUBLE dblFinalValue,
UI_ANIMATION_SECONDS hold);
Parameters
delay
The amount of time by which to delay the instantaneous switch to the final value.
dblFinalValue
The value of the animation variable at the end of the transition.
hold
The amount of time by which to hold the variable at its final value.
CDiscreteTransition::Create
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.
CDiscreteTransition::m_dblFinalValue
The value of the animation variable at the end of the transition.
DOUBLE m_dblFinalValue;
CDiscreteTransition::m_delay
The amount of time by which to delay the instantaneous switch to the final value.
UI_ANIMATION_SECONDS m_delay;
CDiscreteTransition::m_hold
The amount of time by which to hold the variable at its final value.
UI_ANIMATION_SECONDS m_hold;
