Hi Arve,
Exceptions live in the Python realm, so they have nothing to do with
QApplication as far as I know.
You can install an exception handler with sys.excepthook.
Here's a PyQt3 example (which might also work with PyQt4, I haven't
tested):
def handle_exception(exc_type, exc_value, exc_traceback):
filename, line, dummy, dummy = \
traceback.extract_tb(exc_traceback).pop()
filename = os.path.basename(filename)
error = "%s: %s" % (str(exc_type).split(".")[-1], exc_value)
QMessageBox.critical(None, "ERROR",
"There has been an error: "
+ "<b>%s</b> " % error
+ "on line %d, file %s" % (line, filename))
You can (and probably should) close your application then.
You can install this handler with:
sys.excepthook=handle_exception
(Since the handler uses QMessageBox, install it AFTER instanciating your
QApplication.)
Bye,
