Java GUI 自动调整大小 [英] Java GUI Automatically Resizing

问题描述

这里是绘制 GUI 的地方(注意，该类扩展了 JFrame).

Here is where the GUI is drawn(note, the class extends JFrame).

public Cache() {
    SubstanceColorChooserUI col = new SubstanceColorChooserUI();
    while (mode == 0);
    setResizable(false);
    setTitle("Cache");
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    setBounds(100, 100, 483, 374);
    setLocationRelativeTo(null);
    contentPane = new JPanel();
    contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
    setContentPane(contentPane);
    contentPane.setLayout(new BorderLayout());

    textField = new JTextField();
    textField.setBounds(10, 11, 328, 20);
    contentPane.add(textField);
    textField.setColumns(10);

    JButton btnLoadCache = new JButton("Load cache");
    btnLoadCache.addActionListener(new ActionListener() {
        public void actionPerformed(ActionEvent arg0) {
            try {
                String loc = textField.getText();
                if (loc.equals("")) {
                    JOptionPane.showMessageDialog(Cache.this, "Please specify a location for the cache.", "Unable to load", JOptionPane.ERROR_MESSAGE);
                    return;
                }
                if (!loc.endsWith("\\"))
                    loc = loc + "\\";
                cache = new Store(loc);
                loadImages();
            } catch (Exception e) {
                JOptionPane.showMessageDialog(Cache.this, "Cache failed to initialize.\n" + e.getMessage(), "Unable to load", JOptionPane.ERROR_MESSAGE);
            }
        }
    });
    btnLoadCache.setBounds(351, 9, 112, 23);
    contentPane.add(btnLoadCache);

    JSplitPane splitPane = new JSplitPane();
    splitPane.setDividerLocation(150);
    splitPane.setContinuousLayout(true);
    splitPane.setBounds(10, 44, 453, 279);
    contentPane.add(splitPane);

    JPanel panellie = new JPanel();
    panellie.setLayout(new BorderLayout(0, 0));
    panel = new ImagePanel(null);

    scrollPane_1 = new JScrollPane();
    panellie.add(scrollPane_1, "Center");

    scrollPane_1.setViewportView(panel);
    splitPane.setRightComponent(panellie);

    JPanel panel_1 = new JPanel();
    splitPane.setLeftComponent(panel_1);
    panel_1.setLayout(new BorderLayout(0, 0));

    JScrollPane scrollPane = new JScrollPane();
    panel_1.add(scrollPane, BorderLayout.CENTER);

    model = new DefaultListModel<ListedImage>();
    list = new JList<ListedImage>(model);
    list.addListSelectionListener(new ListSelectionListener() {
        public void valueChanged(ListSelectionEvent arg0) {
            if (arg0.getValueIsAdjusting())
                return;
            ListedImage img = list.getModel().getElementAt(list.getSelectedIndex());
            panel.setImage(img.getImage());
        }
    });
    scrollPane.setViewportView(list);

    progressBar = new JProgressBar();
    progressBar.setStringPainted(true);
    progressBar.setDoubleBuffered(true);
    progressBar.setBounds(10, 328, 453, 14);
    contentPane.add(progressBar);

}

当我 setResizeable 为 true 并开始拖动程序变得越来越小时，我将如何做到这一点，我该如何做到这一点，以便框架内的组件(按钮、标签等)在整个过程中调整大小框架正在调整大小

How would I make it so when I setResizeable to true and I start dragging the program to be bigger and smaller, how do I make it so that the components inside of the frame(buttons, labels, etc) resize when the whole Frame is resizes

推荐答案

使用布局管理器而不是为每个组件设置边界.

Use a layout manager instead of setting the bounds for each component.

您希望组件如何移动会因程序而异.

It is going to vary from program to program how you want your components to move.

看看this，然后试着看看哪种布局最适合您.

Take a look at this, and try to see which layout will work best for you.
