Re: [PyOpenGL-Users] Keyboard Input

[Mike C. F. <mcf...@ro...>]

Don't have time to do much testing, but here are some ideas:

    * glutIgnoreKeyRepeat -- use this, then use a timer/polling solution
      so that what you get are the down event, then while the key is
      down you issue the equivalent of a repeat every X milliseconds
      (glutTimerFunc), and you stop when you get the up event.  To do
      this, you need to track the currently-down keys yourself and
      remove them from your tracking table when the up-event comes in.
    * Use PyGame as your GUI library and it's (game-oriented) mechanisms
      for polling current keyboard state (e.g. pygame.key.get_pressed()
      with the same basic event+timer mechanism as for GLUT.  The
      advantage here being that PyGame does all the tracking of
      currently-down keys for you.

HTH,
