IManipulationProcessor interface

The IManipulationProcessor provides functionality for monitoring and responding to multitouch input.

Members

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

Methods

The IManipulationProcessor interface has these methods.

MethodDescription
CompleteManipulation

Call this method when you want manipulation to end. This method raises the ManipulationCompleted event.

GetAngularVelocity

Calculates the rotational velocity that the target object is moving at.

GetExpansionVelocity

Calculates the rate that the target object is expanding at.

GetVelocityX

Calculates and returns the horizontal velocity for the target object.

GetVelocityY

Calculates and returns the vertical velocity.

ProcessDown

Feeds data to the manipulation processor associated with a target.

ProcessDownWithTime

Feeds data including a timestamp to the manipulation processor associated with a target.

ProcessMove

Feeds data to the manipulation processor associated with a target.

ProcessMoveWithTime

Feeds data including a timestamp to the manipulation processor associated with a target.

ProcessUp

Feeds data to the manipulation processor associated with a target.

ProcessUpWithTime

Feeds data including a timestamp to the manipulation processor associated with a target.

 

Properties

The IManipulationProcessor interface has these properties.

PropertyAccess typeDescription

MinimumScaleRotateRadius

Read/write

Specifies how large the distance contacts on a scale or rotate gesture need to be to trigger manipulation.

PivotPointX

Read/write

This property is the horizontal center of the object.

PivotPointY

Read/write

This property is the vertical center of the object.

PivotRadius

Read/write

This property is used to determine how much rotation is used in single finger manipulation.

SupportedManipulations

Read/write

This property is used to indicate which manipulations are supported by an object.
