On Windows,
EventHookin_tkinter.cwill hang on Windows if Python is run with stdin redirected to a pipe. The reason is that on Windows,EventHookchecks for data availability on stdin by calling_kbhit, which reports if a key was hit on the keyboard. With this patch,EventHookfirst checks whether stdin is a console or a pipe, and then calls either_kbhitorPeekNamedPipe, respectively, to establish if input is available on stdin.
