Provides data for the ManipulationDelta event.

System.Object
  System.EventArgs
    System.Windows.RoutedEventArgs
      System.Windows.Input.InputEventArgs
        System.Windows.Input.ManipulationDeltaEventArgs

Namespace:  System.Windows.Input
Assembly:  PresentationCore (in PresentationCore.dll)

[<Sealed>]
type ManipulationDeltaEventArgs =  
    class
        inherit InputEventArgs
    end

The ManipulationDeltaEventArgs type exposes the following members.

  NameDescription
Public propertyCumulativeManipulationGets the cumulated changes of the current manipulation.
Public propertyDeltaManipulationGets the most recent changes of the current manipulation.
Public propertyDeviceGets the input device that initiated this event. (Inherited from InputEventArgs.)
Public propertyHandledGets or sets a value that indicates the present state of the event handling for a routed event as it travels the route. (Inherited from RoutedEventArgs.)
Public propertyIsInertialGets a value that indicates whether the ManipulationDelta event occurs during inertia.
Public propertyManipulationContainerGets the container that defines the coordinates for the manipulation.
Public propertyManipulationOriginGets the point from which the manipulation originated.
Public propertyManipulatorsGets a collection of objects that represents the touch contacts for the manipulation.
Public propertyOriginalSourceGets the original reporting source as determined by pure hit testing, before any possible Source adjustment by a parent class. (Inherited from RoutedEventArgs.)
Public propertyRoutedEventGets or sets the RoutedEvent associated with this RoutedEventArgs instance. (Inherited from RoutedEventArgs.)
Public propertySourceGets or sets a reference to the object that raised the event. (Inherited from RoutedEventArgs.)
Public propertyTimestampGets the time when this event occurred. (Inherited from InputEventArgs.)
Public propertyVelocitiesGets the rates of the most recent changes to the manipulation.

  NameDescription
Public methodCancelCancels the manipulation.
Public methodCompleteCompletes the manipulation without inertia.
Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodInvokeEventHandlerInvokes event handlers in a type-specific way, which can increase event system efficiency. (Inherited from InputEventArgs.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Protected methodOnSetSourceWhen overridden in a derived class, provides a notification callback entry point whenever the value of the Source property of an instance changes. (Inherited from RoutedEventArgs.)
Public methodReportBoundaryFeedbackSpecifies that the manipulation has gone beyond certain boundaries.
Public methodStartInertiaStarts inertia on the manipulation by ignoring subsequent contact movements and raising the ManipulationInertiaStarting event.
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

The ManipulationDeltaEventArgs class contains data about changes in the position of a manipulation. The DeltaManipulation property contains the changes that occurred since the last ManipulationDelta event occurred. The CumulativeManipulation property contains the total changes that occurred for the current manipulation. You use one of those properties to transform the manipulated object.

You can end a manipulation by calling the Complete method or force the manipulation into inertia by calling the StartInertia method.

The following example shows an event handler for the ManipulationDelta event. The example uses the DeltaManipulation property to move, resize, and rotate a Rectangle. The example also checks whether the ManipulationDelta event occurred during inertia and whether the rectangle is touching the edge of a window. If those cases are true, the application stops the manipulation to prevent the rectangle from leaving the visible area of the application. This example is part of a larger example in Walkthrough: Creating Your First Touch Application.
