Java 好看的label-textfield（-button）布局

class myBorderJPanel extends JPanel{        private TitledBorder titledborder;        private JPanel panel = new JPanel();        myBorderJPanel(String title, GridLayout gridlayout){                titledborder = BorderFactory.createTitledBorder(                                BorderFactory.createEtchedBorder(                                  EtchedBorder.LOWERED), title);                titledborder.setTitleFont(new Font("Georgia",Font.BOLD,20));                titledborder.setTitleJustification(TitledBorder.LEFT);                titledborder.setTitlePosition(TitledBorder.DEFAULT_POSITION);                setBorder(BorderFactory.createEmptyBorder(0,10,10,10));                panel.setLayout(gridlayout);                panel.setBorder(titledborder);                add(panel);        }        void addC(Component c){                c.setFont(new Font("Georgia",Font.BOLD,20));                panel.add(c);        }}

使用：

                myBorderJPanel panel1 = new myBorderJPanel("rong",new GridLayout(3,2));                panel1.addC(new JLabel("nx ="));                panel1.addC(new JTextField(5));                panel1.addC(new JLabel("nz ="));                panel1.addC(new JTextField(5));                panel1.addC(new JLabel("nz ="));                panel1.addC(new JTextField(5));
