Example: Using extra D-Bus hooks with a GLib.Application:
public class MyApplication : Application {
private MyApplication () {
Object (application_id: "org.example.application", flags: 0);
set_inactivity_timeout (10000);
}
public override void activate () {
// NOTE: when doing a longer-lasting action here that returns
// to the mainloop, you should use g_application_hold() and
// g_application_release() to keep the application alive until
// the action is completed.
print ("Activated\n");
}
public override bool dbus_register (DBusConnection connection, string object_path) throws Error {
// We must chain up to the parent class:
base.dbus_register (connection, object_path);
// Now we can do our own stuff here. For example, we could export some D-Bus objects
return true;
}
public override void dbus_unregister (DBusConnection connection, string object_path) {
// Do our own stuff here, e.g. unexport any D-Bus objects we exported in the dbus_register
// hook above. Be sure to check that we actually did export them, since the hook
// above might have returned early due to the parent class' hook returning false!
base.dbus_unregister (connection, object_path);
}
public static int main (string[] args) {
MyApplication app = new MyApplication ();
int status = app.run (args);
return status;
}
}
