PhoshDBusDisplayConfig::handle-change-backlight

Declaration

gboolean
handle_change_backlight (
  PhoshDBusDisplayConfig* self,
  GDBusMethodInvocation* invocation,
  guint arg_serial,
  guint arg_output,
  gint arg_value,
  gpointer user_data
)

Description [src]

Signal emitted when a remote caller is invoking the ChangeBacklight() 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_display_config_complete_change_backlight() 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().
