Artikel
07/27/2011

Feeds data, including a timestamp, to a target's manipulation processor for touch-up sequences.

Syntax

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

Parameter

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.

Rückgabewert

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

Hinweise

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

Beispiele


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