GetGestureConfig Function

Retrieves the configuration for which Windows Touch gesture messages are sent from a window.

Syntax

BOOL WINAPI GetGestureConfig(
  __in     HWND hwnd,
  __in     DWORD dwReserved,
  __in     DWORD dwFlags,
  __in     PUINT pcIDs,
  __inout  PGESTURECONFIG pGestureConfig,
  __in     UINT cbSize
);

Parameter

• hwnd [in]
  A handle to the window to get the gesture configuration from.

• dwReserved [in]
  This value is reserved and must be set to 0.

• dwFlags [in]
  A gesture command flag value indicating options for retrieving the gesture configuration. See Remarks for additional information and supported values.

• pcIDs [in]
  The size, in number of gesture configuration structures, that is in the pGestureConfig buffer.

• pGestureConfig [in, out]
  An array of gesture configuration structures that specify the gesture configuration.

• cbSize [in]
  The size of the gesture configuration (GESTURECONFIG) structure.

Rückgabewert

If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero. To get extended error information, use the GetLastError function.

Hinweise

Passing a value other than sizeof(GESTURECONFIG) for the cbSize parameter will cause calls to this function to fail and GetLastError will return ERROR_INVALID_PARAMETER (87 in decimal).

The following table lists the gesture configuration values:

Beispiele

    GESTURECONFIG gc[3];    
    UINT uiGcs = 3;

    ZeroMemory(&gc, sizeof(gc));
    gc[0].dwID  = GID_ZOOM;
    gc[1].dwID  = GID_ROTATE;
    gc[2].dwID  = GID_PAN;
    BOOL bResult = GetGestureConfig(hWnd, 0, 0, &uiGcs, gc, sizeof(GESTURECONFIG));        
    if (!bResult){                
        DWORD err = GetLastError();                                       
    }
