[Twisted-Python] win 32 reactor
by Gabriel Rossetti April 1, 2008

April 1, 2008

Hello, I need to use PyHook, a win32 lib allowing global input monitoring (mouse, keyboard, etc). It uses the PyWin32 extentions, in particular win32com's PumpMessages() function. This is an event loop defined like so : // @pymethod |pythoncom|PumpMessages|Pumps all messages for the current thread until a WM_QUIT message. static PyObject *pythoncom_PumpMessages(PyObject *self, PyObject *args) { MSG msg; int rc; Py_BEGIN_ALLOW_THREADS while ((rc=GetMessage(&msg, 0, 0, 0))==1) { TranslateMessage(&msg); // needed? DispatchMessage(&msg); } Py_END_ALLOW_THREADS if (rc==-1) return PyWin_SetAPIError("GetMessage"); Py_INCREF(Py_None); return Py_None; } my question is ho can I make this work with twisted? Is there a way to use the supplied win32 reactors (there are three I think) or do I have to write one myself? Could someone please point me in the right direction? Thanks, Gabriel

[Twisted-Python] Correct way to handle errors of connectTCP
by Simon Pickles April 1, 2008

April 1, 2008

Hi, I expected reactor.connectTCP to return a deferred. That would have been nice, since callbacks would have handled the outcome. So how to I handle failure with it? I tried: from twisted.internet.error import ConnectionRefusedError print "Connecting..." try: reactor.connectTCP(self.server, self.port, self.f) except ConnectionRefusedError(reason): self.Connect_Failure() return self.Connect_Success() No good. What am I missing? Thank you! Simon -- Linux user #458601 - http://counter.li.org.
