PhoshDBusLoginSession::handle-set-brightness

Declaration 

gboolean
handle_set_brightness (
  PhoshDBusLoginSession* self,
  GDBusMethodInvocation* invocation,
  gchar* arg_subsystem,
  gchar* arg_name,
  guint arg_brightness,
  gpointer user_data
)

Description [src]

Signal emitted when a remote caller is invoking the SetBrightness() D-Bus method.

If a signal handler returns TRUE, it means the signal handler will handle the invocation (e.g. take a reference to invocation and eventually call phosh_dbus_login_session_complete_set_brightness() or e.g. g_dbus_method_invocation_return_error() on it) and no other signal handlers will run. If no signal handler handles the invocation, the G_DBUS_ERROR_UNKNOWN_METHOD error is returned.

Default handler:

The default handler is called after the handlers added via g_signal_connect().
