T:Windows.UI.Composition.Interactions.InteractionTrackerInertiaStateEnteredArgs |
winrt class |
Arguments for the IInteractionTrackerOwner.InertiaStateEntered callback.
The InteractionTrackerOwner.InertiaStateEntered class defines the accessible and up-to-date property values when InteractionTracker enters the inertia state. If registered for the InertiaStateEntered event, values of this object's properties represent the results calculated by the system at the beginning of the inertia state. Using the modified and natural resting positions helps enables scenarios such as scrolling virtualization.
