Hmm.. 2 questions on this today. On Windows PyHook will work. It signals for both Key Up and Key Down events. However it is a Windows only module making use of very platform specific API. I am not sure if there is an equivalent for Linux. -- http://mail.python.org/mailman/listinfo/python-list

Also, I would of course like to know _which_ key has been pressed. On Windows you can listen to the messages WM_KEYDOWN/WM_KEYUP. Or, for a specific key, you can use GetKeyState/GetAsyncKeyState. For the whole keyboard use GetKeyboardState. -- Gabriel Genellina Softlab SRL __ Preguntá. Respondé. Descubrí. Todo lo que querías saber, y lo que ni imaginabas, está en Yahoo!

E.g. On Win only in a rough console msvcrt.kbhit() does it. In PythonWin, IPython, Crust ... things are of course different. On regular Unix terminals you have the sys.stdin file: sys.stdin.read(1) #maybe in a thread and interthread-pass it to your main loop or possibly trick with fcntl.fcntl(sys.stdin, fcntl.F_SETFL, os.O_NDELAY|os.O_NONBLOCK) when nothing is on sys.stdin - you get immediately an IOError: >>> sys.stdin.read(1) Traceback (most recent call last): File "", line 1, in ? IOError: [Errno 11] Resource temporarily unavailable And see also other ioctl, termios, tty, cbreak, curses .. functions to get things early before \n buffering depending on the terminal mode ) Robert -- http://mail.python.org/mailman/listinfo/python-list
keypressed() function
I need a function (blocking or non-blocking) that tells me if a key has been pressed (even before it has been released etc.). Also, I would of course like to know _which_ key has been pressed. I know that this probably does not exist in the Python library already as a platform-independant abstraction (even though it probably could), but then I would at least like solutions that works on Windows and on Linux. /David -- http://mail.python.org/mailman/listinfo/python-list
