    // Set the FixedFilter of ndTimeInterval according to the setting in the ActionBarPage of the gantt chart.
    // The FixedFilter must be set to 'true' or 'false'. This can however not be done (yet?) via Quill.
    // Workaround: use a DataHolder as FilterArgument for the NodeDefinition. Using a DataHolder of type Boolean however results in errors :-(
    // Therefore, dhShowOccurrences is of type LibCal_CalendarRegistry, and it is filled with the CalendarRegistry-instance when
    // btnShowOccurrences is toggled on (i.e. pressed), and cleared otherwise.
    // In this way, showOccurrences := not isnull( dhShowOccurrences.Data() ).
    
    registry := ifexpr( btnShowOccurrences.IsPressed(), LibCal_GlobalState.dhGlobalCalendarRegistry().Data(),
                                                        null( LibCal_CalendarRegistry ) );
    dhShowOccurrences.Data( registry );
    
    // Show a different image when the button is pressed on or not.
    image := ifexpr( btnShowOccurrences.IsPressed(), "CHECKEDCHECKBOX", "EMPTYCHECKBOX" );
    btnShowOccurrences.Image( image );
