IUIAnimationTransitionLibrary2 interface

Defines a library of standard transitions for a specified dimension.

When to implement

Client applications do not implement this interface; custom implementations are not supported.

When to use

Client applications use this interface to create standard transitions. An implementation is provided by the UIAnimationTransitionLibrary object.

Members

The IUIAnimationTransitionLibrary2 interface inherits from the IUnknown interface. IUIAnimationTransitionLibrary2 also has these types of members:

Remarks

Windows Animation includes a library of common transitions that developers can apply to variables through a storyboard. The parameters for specifying a transition depend on the type of transition. For some transitions, the duration of the transition is an explicit parameter; for others, the duration is determined by other parameters, such as speed or acceleration when the transition begins. A transition's initial value or velocity can be overridden if a discontinuous jump is desired, and duration can be queried after the transition is added to a storyboard.

If an application requires an effect that cannot be specified using the transition library, developers can implement custom transitions. A custom transition is created by first implementing the interpolator function for the transition, and then by using a factory object to generate transitions from interpolators. An interpolator must implement the IUIAnimationInterpolator2 interface; an implementation of the transition factory object is provided by the UIAnimationTransitionFactory2 object.
