[pygtk] Callback to PyGtk application from C thread

[e11321 at comcast.net]

Hi,

I have been having trouble with Python threads for a while and decided to rewrite the threading code in C (using GLib threads) but now I am getting output to stdout buffered when I call the PyGtk app from the C thread.  I was wondering if there was a way to post the callback event to the applications main loop somehow so that when the thread returns it processes the callback just like any other Gtk Event (e.g.  mouse click).  

I thought of creating a Python thread with a Queue, and posting an object to the Queue so when the C thread returns the Python thread would see the object in the Queue and send the object to the Gtk code but that seems overly complicated.  I've pasted the C code that invokes the Python callback.  

thanks for any help.

//------------------------------------------------------------------------------
void invoke_event_callback(struct bear_event_t * p)
{
    PyObject *arglist;
    PyObject *result;

    PyGILState_STATE gstate;
    gstate = PyGILState_Ensure();

    arglist = Py_BuildValue("(iss)", p->result, p->src, p->msg);

    result = PyEval_CallObject(event_callback, arglist);

    /* Release the thread. No Python API allowed beyond this point. */
    PyGILState_Release(gstate);

    Py_DECREF(arglist);
}
