+//! [disconnect-all]
+\note Disconnecting all signal-slot connections will also disconnect the
+\l QObject::destroyed() signal if it is connected. Doing so can adversely
+affect classes that rely on this signal for cleaning up resources. It is
+recommended to disconnect only the specific signals that were connected by
+application code.
