    public WideComboBox(Vector items) { 
        super(items); 
    } 
 
    public WideComboBox(ComboBoxModel aModel) { 
        super(aModel);

    private boolean layingOut = false; 
 
    public void doLayout(){ 
        try{ 
            layingOut = true; 
            super.doLayout(); 
        }finally{ 
            layingOut = false; 
        } 
    } 
 
    public Dimension getSize(){ 
        Dimension dim = super.getSize(); 
        if(!layingOut) 
            dim.width = Math.max(dim.width, getPreferredSize().width); 
        return dim; 
    }
