Detailed Description

Interface defining a generic animation.

This interface is used by objects implementing the Activity interface to drive the animation effect. Objects implementing this interface will receive time-varying animation values, which they can forward to the appropriate attributes. The type of these animation values is given in derived interfaces.

Member Function Documentation

end()

virtual void slideshow::internal::Animation::end ( )

pure virtual

Notify that the animation is about to end.

Implemented in slideshow::internal::SlideChangeBase.

prefetch()

virtual void slideshow::internal::Animation::prefetch ( )

pure virtual

Notify that the animation going active soon.

Implementers should preload any buffers, and create any expensive objects at this time.

Parameters

rShape	Shape to apply this animation to.
rAttrLayer	Attribute layer to play the animation on.

Implemented in slideshow::internal::SlideChangeBase.

start()

virtual void slideshow::internal::Animation::start ( const AnimatableShapeSharedPtr &  rShape, const ShapeAttributeLayerSharedPtr &  rAttrLayer  )

pure virtual

Notify that the animation is about to begin.

Implementers are free to start accompanying effects, such as sounds, and the animation timer now.

Parameters

rShape	Shape to apply this animation to.
rAttrLayer	Attribute layer to play the animation on.

Implemented in slideshow::internal::SlideChangeBase.
