这是绘制GUI的地方(注意,该类扩展了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);

}

当我将setResizeable设置为true并且我开始拖动程序变得越来越小时,我怎么能这样做呢?我该怎么做才能让框架里面的组件(按钮,标签等)整体调整大小框架调整大小

使用布局管理器而不是为每个组件设置边界。

不同程序会因您希望组件移动的方式而异。

查看this,然后尝试查看最适合您的布局。

1。您可以使用setSize()方法设置 JFrame尺寸

2. 您可以通过设置isResizable(false)来选择修复 JFrame的大小

3。使用 GroupLayout,由NetBeans团队在2005年开发立即免费试用Google提供的Windows Builder Pro 。在这里,您可以选择GroupLayout,然后将组件拖放到JFrame中,即使您希望可以手动编辑GUI代码。
