It is internal OpenCV tool.

Would something like cv::currentParallelFramework() but for UI work for you?

My code is

#ifdef HAVE_WIN32UI
#define KEY_CODE_ESC 0x1b
#define KEY_CODE_DOWN_ARROW 0x280000
#endif

#ifdef HAVE_GTK3
#define KEY_CODE_ESC 0x10001b
#define KEY_CODE_DOWN_ARROW 0x10ff54
#endif

keyCode=0;
while (keyCode!= KEY_CODE_ESC)
{
  keyCode = cv::waitKeyEx(10);
  switch (keyCode ) {
                  case KEY_CODE_DOWN_ARROW:
....
}

I don't know how to do it without constant expression.
