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?
-- A.
