IManipulationProcessor::ProcessMoveWithTime method (manipulations.h)

Article
02/22/2024

Feeds movement data, including a time stamp, for the target object to its manipulation processor.

Syntax

HRESULT ProcessMoveWithTime(
  MANIPULATOR_ID manipulatorId,
  FLOAT          x,
  FLOAT          y,
  DWORD          timestamp
);

Parameters

manipulatorId

The identifier for the touch contact to be processed.

x

The horizontal coordinate data associated with the target.

y

The vertical coordinate data associated with the target.

timestamp

The time of the data event.

Return value

If the method succeeds, it returns S_OK. If it fails, it returns an HRESULT error code such as E_FAIL.

Remarks

It is possible to receive touch events out of the order they were produced. To fix this, you should extract the time stamp from the TOUCHINPUT structure when you process events.

Examples


static void ProcessMove(TOUCHINPUT* pTouchInput, IManipulationProcessor* pManipulationProcessor){
  pManipulationProcessor->ProcessMoveWithTime(
    pTouchInput->dwID, 
    static_cast<float>(pTouchInput->x), 
    static_cast<float>(pTouchInput->y), 
    pTouchInput->dwTime
  );
}
