I'm not exactly sure what you want here :-) but if you want to capture when the 'Print Screen' key (or any other key) has actually been pressed, try pyHook. Note: pyHook only works on Windows! Here's some sample code: <code> """ Captures a press of the 'Print Screen' key. The following requires ctypes and pyHook. ctypes is standard in Python2.5. ctypes -> http://sourceforge.net/projects/ctypes/ pyHook -> http://www.cs.unc.edu/Research/assist/developer.shtml """ from ctypes import windll, byref from ctypes.wintypes import MSG import pyHook user32 = windll.user32 def keyboardEvent(event): if event.KeyID == 44: print "You hit 'Print Screen'!" return True hm = pyHook.HookManager() hm.KeyDown = keyboardEvent hm.HookKeyboard() msg = MSG() while user32.GetMessageA(byref(msg), None, 0, 0): user32.TranslateMessage(byref(msg)) user32.DispatchMessageA(byref(msg)) </code> HTH, Bill _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
