[pygtk] PyGtk_FatalExceptions replacement?

[Andrew Reid]

  Hi all --

  We're in the process of cleaning up the port of our application
from pygtk-0.6.9 to pygtk-2.6.1.  Most things transferred over 
in a reasonably straightforward way, but there's an issue we put
off, and I'm not sure how to handle it.

  We have some mouse callbacks from a GtkCanvas, which are handled
in C++ code, which then calls out to Python to run a handler.  
In the pygtk-0.6.9 version, there's an fatal-error check in the C++
handler, like this:  (The example is actually from the config callback,
but the mouse-event ones are similar)

> void CanvasObj::configure_event_callback( ... ) {
>   PyGILState_STATE state = (PyGILState_STATE) pyg_gil_state_ensure();
>   try {
>     PyObject *args = Py_BuildValue("iiii", 
> 				   (int)(a->x), (int)(a->y), 
> 				   (int)(a->width), (int)(a->height));
>     if (args) {
>       // Call the Python handler for the configuration event...
>       PyObject *result = PyObject_CallObject(config_callback, args);
>       if (result==NULL) {
> 	  if (PyGtk_FatalExceptions) {  // <--- ERROR CHECK IS HERE
> 	    gtk_main_quit();
>      ... etc ...

  I've been poking around to see if there is a pygtk2 equivalent of 
this, but there doesn't seem to be.  If this functionality is available,
it seems prudent to use it.  Are these errors detectable by some 
other means now?
