IManipulationProcessor::ProcessDown method (manipulations.h)

  • Article

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
);

Parameters

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.

Return value

Returns S_OK on success, otherwise returns an error code such as E_FAIL.

Remarks

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.
