This releases the GIL, so I guess it should be ok to call it in a background thread from Python. Should be all that is needed. Andreas Am Montag, den 31.03.2008, 18:28 +0200 schrieb Gabriel Rossetti:

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

The three reactors you're probably referring to are selectreactor, win32er, and IOCP reactor. Of these, only the latter two do anything particular to Windows (the first just uses select(2), which Windows sort of has). win32er is basically a loop around MsgWaitForMultipleObjects. IOCP reactor is basically a loop around GetQueuedCompletionStatus. One way to look at your question is to consider how GetMessage/TranslateMessage/DispatchMessage interact with MWFMO and GQCS. This is basically a Windows API question, so I can't answer it, since I know very little about Windows APIs. Jean-Paul
