Provides data for the ManipulationDelta event.
Assembly: PresentationCore (in PresentationCore.dll)
Thetype exposes the following members.
|CumulativeManipulation||Gets the cumulated changes of the current manipulation.|
|DeltaManipulation||Gets the most recent changes of the current manipulation.|
|Device||Gets the input device that initiated this event. (Inherited from InputEventArgs.)|
|Handled||Gets 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.)|
|IsInertial||Gets a value that indicates whether the ManipulationDelta event occurs during inertia.|
|ManipulationContainer||Gets the container that defines the coordinates for the manipulation.|
|ManipulationOrigin||Gets the point from which the manipulation originated.|
|Manipulators||Gets a collection of objects that represents the touch contacts for the manipulation.|
|OriginalSource||Gets the original reporting source as determined by pure hit testing, before any possible Source adjustment by a parent class. (Inherited from RoutedEventArgs.)|
|RoutedEvent||Gets or sets the RoutedEvent associated with this RoutedEventArgs instance. (Inherited from RoutedEventArgs.)|
|Source||Gets or sets a reference to the object that raised the event. (Inherited from RoutedEventArgs.)|
|Timestamp||Gets the time when this event occurred. (Inherited from InputEventArgs.)|
|Velocities||Gets the rates of the most recent changes to the manipulation.|
|Cancel||Cancels the manipulation.|
|Complete||Completes the manipulation without inertia.|
|Equals(Object)||Determines whether the specified object is equal to the current object. (Inherited from Object.)|
|GetHashCode||Serves as the default hash function. (Inherited from Object.)|
|GetType||Gets the Type of the current instance. (Inherited from Object.)|
|ReportBoundaryFeedback||Specifies that the manipulation has gone beyond certain boundaries.|
|StartInertia||Starts inertia on the manipulation by ignoring subsequent contact movements and raising the ManipulationInertiaStarting event.|
|ToString||Returns a string that represents the current object. (Inherited from Object.)|
The 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.
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.
