IManipulationProcessor::ProcessDown Method

The ProcessDown method feeds touch down data to the manipulation processor associated with a target.

Syntax

HRESULT ProcessDown(
  MANIPULATOR_ID manipulatorId,
  FLOAT x,
  FLOAT y
);

Parameter

• manipulatorId
  The identifier for the touch contact that you want to process.

• x
  The horizontal coordinate data associated with the target.

• y
  The vertical coordinate data associated with the target.

Rückgabewert

Hinweise

This method takes a timestamp using system time rather than from the touch hardware. To improve the experience in cases where performance is degrading you should use the ProcessDownWithTime method.
