GetTouchScreen()

EXTERN_C CCAUXDLL_API TOUCHSCREENHANDLE CCAUXDLL_CALLING_CONV CrossControl::GetTouchScreen

(

void

)

Factory function that creates instances of the TouchScreen object.

Supported Platform(s): XL, XM, XS, XA

Returns

TOUCHSCREENHANDLE to an allocated TouchScreen object. The returned handle needs to be deallocated using the TouchScreen_release(TOUCHSCREENHANDLE) method when it's no longer needed. Returns NULL if it fails to allocate memory.

Example Usage:

  TOUCHSCREENHANDLE pTouchScreen = ::GetTouchScreen();
  assert(pTouchScreen);
 
  touchscreen_example(pTouchScreen);
 
  TouchScreen_release(pTouchScreen);

TouchScreen_getAdvancedSetting()

EXTERN_C CCAUXDLL_API eErr CCAUXDLL_CALLING_CONV CrossControl::TouchScreen_getAdvancedSetting	(	TOUCHSCREENHANDLE	,
		TSAdvancedSettingsParameter	param,
		uint16_t *	data
	)

Get advanced touch screen settings. See the description of TSAdvancedSettingsParameter for a description of the parameters.

Supported Platform(s): XL, XM, XS, XA

Parameters

param	The setting to get.
data	The current data for the setting.

Returns

error status. 0 = ERR_SUCCESS, otherwise error code. See the enum eErr for details.

Example Usage:

  err = TouchScreen_getAdvancedSetting(pTouchScreen, TS_DEBOUNCE_TIME, &debouncetime);
  if (err == ERR_SUCCESS)
  {
    cout << "Touchscreen debounce time is set to: " << (int)debouncetime  << " ms" << endl;
  }
  else 
  {
    cout << "Error(" << err << ") in function getAdvancedSetting: " << GetErrorStringA(err) << endl;
  }

TouchScreen_getMode()

EXTERN_C CCAUXDLL_API eErr CCAUXDLL_CALLING_CONV CrossControl::TouchScreen_getMode	(	TOUCHSCREENHANDLE	,
		TouchScreenModeSettings *	config
	)

Get Touch Screen mode. Gets the current mode of the USB profile.

Supported Platform(s): XL, XM, XS, XA

Parameters

config

The current mode.

Returns

error status. 0 = ERR_SUCCESS, otherwise error code. See the enum eErr for details.

Example Usage:

  err = TouchScreen_getMode(pTouchScreen, &ts_mode);
  if (err == ERR_SUCCESS)
  {
    switch(ts_mode)
    {
    case MOUSE_NEXT_BOOT: cout << "USB profile is set to Mouse profile (active next boot)" << endl; break; 
    case TOUCH_NEXT_BOOT: cout << "USB profile is set to Touch profile (active next boot)" << endl; break; 
    case MOUSE_NOW: cout << "USB profile is set to Mouse profile" << endl; break; 
    case TOUCH_NOW: cout << "USB profile is set to Touch profile" << endl; break; 
    default: cout << "Error: invalid setting returned from getMode" << endl; break; 
    }   
  } 
  else if (err == ERR_NOT_SUPPORTED) 
  {
      cout << "Function TouchScreen_getMode() is not supported on this platform" << endl;
  }
  else 
  {
    cout << "Error(" << err << ") in function getMode: " << GetErrorStringA(err) << endl;
  }

TouchScreen_getMouseRightClickTime()

EXTERN_C CCAUXDLL_API eErr CCAUXDLL_CALLING_CONV CrossControl::TouchScreen_getMouseRightClickTime	(	TOUCHSCREENHANDLE	,
		uint16_t *	time
	)

Get mouse right click time. Applies only to the mouse profile. Use the OS settings for the touch profile.

Supported Platform(s): XL, XM, XS, XA

Parameters

time	The right click time, in milliseconds.

Returns

error status. 0 = ERR_SUCCESS, otherwise error code. See the enum eErr for details.

Example Usage:

  err = TouchScreen_getMouseRightClickTime(pTouchScreen, &rightclicktime);
  if (err == ERR_SUCCESS)
  {
    cout << "Right click time is set to: " << (int)rightclicktime << " ms" << endl;
  }
  else 
  {
    cout << "Error(" << err << ") in function getMouseRightClickTime: " << GetErrorStringA(err) << endl;
  }

Supported Platform(s): XL, XM, XS, XA

Returns

-

Example Usage:

 
  TOUCHSCREENHANDLE pTouchScreen = ::GetTouchScreen();
  assert(pTouchScreen);
 
  touchscreen_example(pTouchScreen);
 
  TouchScreen_release(pTouchScreen);
