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. -- Dr. Andrew C. E.
