CConstantTransition Class

  • Article

Encapsulates a constant transition.

Syntax

class CConstantTransition : public CBaseTransition;

Members

Public Constructors

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

Public Methods

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

Public Data Members

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

Remarks

During a constant transition, the value of an animation variable remains at the initial value over the duration of the transition. 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.
