RiverWare 6.4 development: virtual definitions of 'show' 
(used to be virtual in Qt3, but is not in Qt4) -- DANGER).
(For full such list, Google: "Porting to Qt4 - Virtual Functions").

  Q3GUI/GusDialog.hpp:      virtual void show();
  Q3GUI/GusTreeWidget.hpp:  virtual void show();
  Q3GUI/PlotDialog.hpp:     virtual void show();
  Q3GUI/Workspace.hpp:      virtual void show();

THESE ARE OK (still virtual at QWidget). But should all be 'override': 

Q3GUI/DiagOutputQMainWindow.hpp:      virtual void showEvent (QShowEvent*);
Q3GUI/DiagOutputWidget.hpp:           virtual void showEvent (QShowEvent*);
Q3GUI/DiagOutputWidget.hpp:           virtual void showEvent (QShowEvent*);
Q3GUI/FloatValueEditor.hpp:           virtual void showEvent (QShowEvent*);
Q3GUI/GusDialog.hpp:                  virtual void showEvent (QShowEvent*);
Q3GUI/OutputManager.hpp:              virtual void showEvent (QShowEvent*);
Q3GUI/PeriodicSlotCfg.hpp:            virtual void showEvent (QShowEvent*);
Q3GUI/PlotDialog.hpp:                 virtual void showEvent (QShowEvent*);
Q3GUI/PlotPageSelPanel.hpp:           virtual void showEvent (QShowEvent*);
Q3GUI/RowColLabelEditor.hpp:          virtual void showEvent (QShowEvent*);
Q3GUI/RwNoticeBox.hpp:                virtual void showEvent (QShowEvent*);
Q3GUI/Workspace.hpp:                  void showEvent (QShowEvent*);
QtRun/RunAnalRulesGridCellLegend.hpp: virtual void showEvent (QShowEvent*);
QtRun/RunAnalSimGridCellLegend.hpp:   virtual void showEvent (QShowEvent*);
QtSCT/SctDialog.hpp:                  void showEvent (QShowEvent*) override;
QtSCT/SctFindSlotDialog.hpp:          virtual void showEvent (QShowEvent*);
QtUtils/DisplayCompressPanel.hpp:     virtual void showEvent (QShowEvent*); 
QtUtils/MessageListBox.hpp:           virtual void showEvent (QShowEvent*);
QtUtils/RwCellQLineEdit.hpp:          virtual void showEvent (QShowEvent*);
QtUtils/RwGraphicsView.hpp:           virtual void showEvent (QShowEvent*);
QtUtils/SlotQTreeWidget.hpp:          void showEvent (QShowEvent*) override;
