Using other keys for the waitKey() function of opencv

Question

I\'m working on a program (python ,opencv) in which I use the spacebar to go to the next frame, and Esc to exit the program. These are the only two

Answer 1

For C++:

In case of using keyboard characters/numbers, an easier solution would be:

int key = cvWaitKey();

switch(key)
{
   case ((int)('a')):
   // do something if button 'a' is pressed
   break;
   case ((int)('h')):
   // do something if button 'h' is pressed
   break;
}
