# This example demonstrates how to get and change firewall zone in a
# connection. It uses GObject Introspection instead of direct D-Bus calls.
# 'zone' is a property of 'connection' setting in a connection. You can't
# get/set individual properties directly. Rather you ask for the whole
# connection, change a property and update the connection back into
# NetworkManager.
# If you used D-Bus calls, you would call GetSettings() and then Update().
