Hello everybody out there!
I need to inhibit screen-saver while an application is in full-screen
mode (and uninhibit it when switching back into windowed mode). If I am
not mistaken, according to
<http://people.gnome.org/~mccann/gnome-screensaver/docs/gnome-screensaver.html>,
I need to send method « Inhibit » to service « org.gnome.ScreenSaver »
through D-Bus current session bus.
To achieve this, I have read D-Bus tutorial from Freedesktop
(<http://dbus.freedesktop.org/doc/dbus-tutorial.html>) and dive into
Glibmm D-BUS API documentation
(<https://developer.gnome.org/glibmm/2.34/group__DBus.html>). I got
totally lost, I need help finding my way out.
So far, I have made the following code:
void inhibitScreenSaver () {
/* Proxy connected to D-Bus. */
Glib::RefPtr<Gio::DBus::Proxy> proxy;
/* Message to be send. */
Glib::RefPtr<Gio::DBus::Message> message =
Gio::DBus::Message::create_method_call(proxy->get_name(),
"/org/gnome/ScreenSaver",
proxy->get_interface_name(),
"Inhibit");
/* Connexion to current session bus from D-Bud. */
Glib::RefPtr<Gio::DBus::Connection> connection =
Gio::DBus::Connection::get_sync(Gio::DBus::BUS_TYPE_SESSION);
if (!connection->send_message(message))
g_warning("Impossible to inhibit screen-saver.");
}
Of course, this code generates a segmentation fault, as "proxy" is not
initialised. The thing is, I do not have a clue on how to initialise the
proxy in a proper way. Also, "connection" initialisation does not seem
quite right. Actually, I am not sure I am not using a completely wrong
approach.
Can someone help me out this?
Best regards.
Yoann
