完成此任务的最佳布局管理器

Question

我有（2）个JTextAreas（输入文本和输出文本）

（2）JComboBoxes（AutoDetect和TranslateTo）

请查看附件中的照片以了解目标。

我正在尝试使用某个我曾尝试过FlowLayout，SpringLayout的布局管理器来获得此布局，但这些方法并没有取得理想的结果。 这是我的代码

public class translate extends JFrame implements ActionListener{
/*
    Our Langauges of choice we can add more if desired in the future 
    */

    String[] nativeString = { "Auto-Detect"};
    String[] translateString = { "Español", "中文", "Francais", "Italiano", "Deutsche" , "English" };
     JComboBox nativeLanguage;
     JComboBox translateTo;
     JButton execute;
      final JPanel topRight;
      final JPanel topLeft;
      final JPanel bottomLeft;
      JPanel bottomRight;
      JLabel tR;
       JLabel tL;
      JLabel bR;
       JLabel bL;


      JRadioButton local;
      JRadioButton mainArea;
      JTextArea input;
      JTextArea output;

    public translate() throws Exception{

      super("Translation Service");
      JOptionPane.showMessageDialog(null, "Translation Services Require A NetWork Function To Make Calls");
      Translate.setClientId("xxxxxxxxx");
      Translate.setClientSecret("Xxxxxxxxxxxx);
      setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
      setSize(700,400);
      setLocationRelativeTo(null);
      setResizable(true);
      setLookAndFeel();
      SpringLayout spring = new SpringLayout();
      setLayout(spring);


       input= new JTextArea();
      JScrollPane inScroll = new JScrollPane();
      input.add(inScroll);
     input.setEditable(true);
     input.setLineWrap(true);


     execute = new JButton("Translate");
    execute.addActionListener(this);
     output = new JTextArea();
     JScrollPane outScroll = new JScrollPane();
     output.add(outScroll);
      output.setEditable(true);
     output.setLineWrap(true);
     output.setVisible(true);
      /*
      Our JComboBoxes for user to selct langauge they want to choose
      */
      nativeLanguage = new JComboBox(nativeString);
      translateTo = new JComboBox(translateString);

      nativeLanguage.addActionListener(this);
      translateTo.addActionListener(this);
      // JLabels

      tR = new JLabel("Auto-Detect");
      tL = new JLabel ("Target Langauge");
      // FlowLayout fl = new FlowLayout();
      SpringLayout sp = new SpringLayout();
      setLayout(sp);
      // setLayout(fl);
      //1
       topRight = new JPanel();
      // topRight.setLayout(new BoxLayout(topRight, BoxLayout.PAGE_AXIS));
       topRight.add(nativeLanguage);
       topRight.add(tR);


       //2
       topLeft = new JPanel();
      // topLeft.setLayout(new BoxLayout(topLeft, BoxLayout.PAGE_AXIS));
       topLeft.add(translateTo);
       topLeft.add(tL);

       //3

      bottomRight = new JPanel();
     // bottomRight.setLayout(new BoxLayout(bottomRight, BoxLayout.PAGE_AXIS));
      bottomRight.add(input);

       //4
      bottomLeft = new JPanel();
    //  bottomLeft.setLayout(new BoxLayout(bottomLeft, BoxLayout.LINE_AXIS));
     bottomLeft.add(output);




     add(topRight, SpringLayout.NORTH);
     add(topLeft, SpringLayout.NORTH);
     add(bottomRight, SpringLayout.SOUTH);
     add(bottomLeft, SpringLayout.SOUTH);

   setVisible(true);

    }

Answer 1

我认为GridLayout为您工作。 如果您想要更大的灵活性，也可以使用GridBagLayout 。 这里是所有布局管理器的链接和链接的示例。

但是，您是否真的想通过秋千做到这一点？ 看来您刚开始使用项目的GUI部分，因此也许您应该考虑使用javafx而不是swing。
