Question

我试图弄清楚应该在JFrame上使用哪些布局来完成此布局。我正在尝试编写GUI而不是使用可视化GUI制作工具。到目前为止，我只能让它看起来像这样：

这是上面GUI的源代码：http://pastebin.com/s06pareG

    /**
     * Initialize the contents of the frame.
     */
    private void initialize() {
            frame = new JFrame();
            frame.setBounds(100, 100, 450, 300);
            frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
            //frame.getContentPane().setLayout(new FlowLayout(FlowLayout.CENTER, 5, 5));

            JPanel upPanel = new JPanel();
            upPanel.setLayout(new GridLayout(2,3));

            JLabel data = new JLabel("Data Source Name:");
            upPanel.add(data);
            JTextField dataText = new JTextField();
            upPanel.add(dataText);
            JLabel desc = new JLabel("Description:");
            upPanel.add(desc);
            JTextField descText = new JTextField();
            upPanel.add(descText);

            JPanel midPanel = new JPanel();
            midPanel.setBorder(new TitledBorder(null, "Database", TitledBorder.LEADING, TitledBorder.TOP, null, null));
            JLabel dbTitle = new JLabel("Database");
            JButton select = new JButton("Select...");
            JButton create = new JButton("Create...");
            JButton repair = new JButton("Repair...");
            JButton compact = new JButton("Compact...");

            JPanel eastPanel = new JPanel();
            eastPanel.setLayout(new GridLayout(4,1));

            JButton ok = new JButton("OK");
            JButton cancel = new JButton("Cancel");
            JButton help = new JButton("Help");
            JButton advanced = new JButton("Advanced...");
            eastPanel.add(ok); eastPanel.add(cancel); eastPanel.add(help); eastPanel.add(advanced);

            frame.getContentPane().add(upPanel, BorderLayout.NORTH);
            frame.getContentPane().add(midPanel, BorderLayout.WEST);
            midPanel.setLayout(new BorderLayout(0, 0));
            midPanel.add(dbTitle);
            midPanel.add(select);
            midPanel.add(create);
            midPanel.add(repair);
            midPanel.add(compact);
            frame.getContentPane().add(eastPanel, BorderLayout.EAST);

    }

我正在考虑制作JFrame绝对布局，然后使用GridLayout创建4个JPanel。另外，我无法将“Database：”标签放在自己的行上并将JButton置于其下方。我应该研究哪些类型的布局和自定义功能来实现这种外观？

Answer 1

将布局分解为基本的责任范围，单独关注每个区域并管理自己的布局要求

因此，正如我所见，您有四个基本功能区域......

您需要将它们分解为各自的组件，并专注于布局和功能要求

第01部分

所以，这是非常基本的

public class SourcePane extends JPanel {
    private JTextField datasourceName;
    private JTextField desciption;

    public SourcePane() {
        setLayout(new GridBagLayout());
        GridBagConstraints gbc = new GridBagConstraints();
        gbc.gridx = 0;
        gbc.gridy = 0;
        gbc.anchor = GridBagConstraints.WEST;

        add(new JLabel("Data Source Name: "), gbc);
        gbc.gridy++;
        add(new JLabel("Description: "), gbc);

        gbc.gridx++;
        gbc.gridy = 0;
        gbc.weightx = 1;
        gbc.fill = GridBagConstraints.HORIZONTAL;

        add((datasourceName = new JTextField(10)), gbc);
        gbc.gridy++;
        add((desciption = new JTextField(10)), gbc);
    }

    public String getDataSourceName() {
        return datasourceName.getText();
    }

    public String getDescription() {
        return desciption.getText();
    }

    public void setDataSourceName(String name) {
        datasourceName.setText(name);
    }

    public void setDescription(String description) {
        desciption.setText(description);
    }

}

我还添加了一些访问器，我不会将其添加到其余代码中，但提供了如何在组件之间获取/设置信息的想法

第02部分

这比较困难，因为Database:标签旁边有一个额外标签的建议。 “可能”可以在单一布局中完成此操作，但使用其他容器并进一步复合布局会更容易

public class DatabasePane extends JPanel {

    private JButton select, create, repair, compact;
    private JLabel database;

    public DatabasePane() {
        setLayout(new GridBagLayout());
        setBorder(new CompoundBorder(new TitledBorder("Database"), new EmptyBorder(12, 0, 0, 0)));
        GridBagConstraints gbc = new GridBagConstraints();
        gbc.gridx = 0;
        gbc.gridy = 0;
        gbc.anchor = GridBagConstraints.WEST;
        gbc.insets = new Insets(0, 0, 0, 4);

        JPanel panel = new JPanel(new GridBagLayout());
        panel.add(new JLabel("Database: "), gbc);
        gbc.gridx++;
        gbc.weightx = 1;
        gbc.fill = GridBagConstraints.HORIZONTAL;
        gbc.insets = new Insets(0, 0, 0, 0);
        panel.add((database = new JLabel()), gbc);

        gbc.gridx = 0;
        gbc.gridy = 0;
        gbc.weightx = 1;
        gbc.gridwidth = GridBagConstraints.REMAINDER;
        gbc.fill = GridBagConstraints.HORIZONTAL;
        gbc.insets = new Insets(4, 4, 4, 4);
        add(panel, gbc);

        gbc.gridwidth = 1;
        gbc.weightx = 0.25;
        gbc.gridy++;
        gbc.fill = GridBagConstraints.HORIZONTAL;
        add((select = new JButton("Select")), gbc);
        gbc.gridx++;
        add((create = new JButton("Create")), gbc);
        gbc.gridx++;
        add((repair = new JButton("Repair")), gbc);
        gbc.gridx++;
        add((compact = new JButton("Compact")), gbc);
    }

}

第03部分

同样，这似乎有点复杂，因为Database:按钮似乎有一个额外的标签。您可以简单地使用按钮text属性，但我选择进一步演示复合布局的想法

public class SystemDatabasePane extends JPanel {

    private JRadioButton none, database;
    private JLabel databaseLabel;
    private JButton systemDatabase;

    public SystemDatabasePane() {
        setLayout(new GridBagLayout());
        setBorder(new CompoundBorder(new TitledBorder("System Database"), new EmptyBorder(8, 0, 0, 0)));
        GridBagConstraints gbc = new GridBagConstraints();
        gbc.gridx = 0;
        gbc.gridy = 0;
        gbc.insets = new Insets(0, 0, 0, 4);
        gbc.anchor = GridBagConstraints.WEST;

        JPanel panel = new JPanel(new GridBagLayout());
        panel.add((none = new JRadioButton("None")), gbc);
        gbc.gridy++;
        panel.add((none = new JRadioButton("Database: ")), gbc);

        gbc.gridx++;
        gbc.weightx = 1;
        gbc.fill = GridBagConstraints.HORIZONTAL;
        panel.add((databaseLabel = new JLabel("")), gbc);

        gbc.gridx = 0;
        gbc.gridy = 0;
        gbc.weightx = 1;
        gbc.gridwidth = GridBagConstraints.REMAINDER;
        gbc.fill = GridBagConstraints.HORIZONTAL;
        gbc.insets = new Insets(4, 4, 4, 4);
        add(panel, gbc);

        gbc.gridy++;
        gbc.fill = GridBagConstraints.NONE;
        gbc.anchor = GridBagConstraints.CENTER;
        add((systemDatabase = new JButton("System Database...")), gbc);
        systemDatabase.setEnabled(false);
    }

}

第04部分

最后，“行动”小组。这实际上相对简单，但是利用GridBagLayout及其约束的属性来在一个布局中完成整个事情

public class ActionPane extends JPanel {

    private JButton okay, cancel, help, advanced, options;

    public ActionPane() {
        setLayout(new GridBagLayout());
        GridBagConstraints gbc = new GridBagConstraints();
        gbc.gridx = 0;
        gbc.gridy = 0;
        gbc.gridwidth = GridBagConstraints.REMAINDER;
        gbc.fill = GridBagConstraints.HORIZONTAL;
        gbc.weightx = 1;
        gbc.insets = new Insets(4, 4, 4, 4);

        add((okay = new JButton("Ok")), gbc);
        gbc.gridy++;
        add((cancel = new JButton("Cancel")), gbc);
        gbc.gridy++;
        add((help = new JButton("Help")), gbc);
        gbc.gridy++;
        add((advanced = new JButton("Advanced")), gbc);
        gbc.gridy++;
        gbc.weighty = 1;
        gbc.anchor = GridBagConstraints.SOUTH;
        add((options = new JButton("Options >>")), gbc);
    }

}

全部放在一起

然后简单地将所有单独的元素放在一个单一的布局中

public class DatabasePropertiesPane extends JPanel {

    private SourcePane sourcePane;
    private DatabasePane databasePane;
    private SystemDatabasePane systemDatabasePane;
    private ActionPane actionPane;

    public DatabasePropertiesPane() {
        setLayout(new GridBagLayout());
        GridBagConstraints gbc = new GridBagConstraints();
        gbc.gridx = 0;
        gbc.gridy = 0;
        gbc.weightx = 1;
        gbc.weighty = 0.33;
        gbc.anchor = GridBagConstraints.WEST;
        gbc.fill = GridBagConstraints.BOTH;
        gbc.insets = new Insets(4, 4, 4, 4);

        add((sourcePane = new SourcePane()), gbc);
        gbc.gridy++;
        add((databasePane = new DatabasePane()), gbc);
        gbc.gridy++;
        add((systemDatabasePane = new SystemDatabasePane()), gbc);

        gbc.gridy = 0;
        gbc.gridx++;
        gbc.gridheight = GridBagConstraints.REMAINDER;
        gbc.fill = GridBagConstraints.VERTICAL;
        gbc.weighty = 1;
        gbc.weightx = 0;
        add((actionPane = new ActionPane()), gbc);
    }

}

Answer 2

不幸的是，它对这些部分的说法不好，但Netbeans＆＃39; GUI Builder非常适合这种项目。这张图片中的GUI花了我大约五分钟的时间来构建：

我实际上录制了一段视频，但视频效果并不好，因为我太便宜无法支付好的屏幕录制软件费用。无论如何，我推荐Netbeans GUI Builder。学习曲线根本不陡（特别是与手写布局管理器相比），它可以做任何其他布局管理器可以做的任何事情，并且更快。

下面是生成的代码，但我强烈建议您自己动手，因为Netbeans还会生成一个.xml文件，这对于GUI Builder的正常运行至关重要。如果如果你想在未来做出改变，你需要GUI Builder这样做（其中一个缺点，但对我而言是次要的）。
