At end of this sequence, connect aboutToQuit to the shortcut_manager and resource_manager function that deletes instance. * octave-dock-widget.cc: (octave_dock_widget::~octave_dock_widget): Rename to save_settings. Return if variable 'settings' is not valid object pointer. (octave_dock_widget::save_settings): Similar code as destructor was. * octave-dock-widget.h: (octave_dock_widget::~octave_dock_widget): Provide empty destructor.
