问题


I am trying to figure out what layouts should be used on the JFrame to get this layout accomplished. I am trying to code the GUI rather than use visual GUI-making tools. So far I was only able to get it to look like this:

This is the source code for the GUI above: 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);

    }

I was thinking about making the JFrame absolute layout and then creating 4 JPanels with GridLayout. Also, I'm having trouble making the "Database:" label sit on its own row and placing the JButtons below it. What types of layouts and customizing functions should I look into to accomplish this look?


回答1:


Break down you layout into it's basic areas of responsibility, focusing each area individually and managing it's own layout requirements

So, as I see, you have four basic areas of functionality...

You need to break these apart into their own individual components and focus on there layout and functional requirements

Part 01

So, this is pretty basic

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);
    }

}

I've also added some accessors, which I won't be adding to the rest of the code, but provides the idea of how you might get/set information between the components

Part 02

This is suitably more difficult, as there is a suggest of an additional label next to the Database: label. It "might" be possible to get this done in a single layout, but it would be easier to use an additional container and further compound the layouts

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);
    }

}

Part 03

Again, this is a little more complex then it seems, as the Database: button seems to have an additional label. You could simply make use of the buttons text property, but I've chosen to further demonstrate the idea of compound layouts

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);
    }

}

Part 04

And finally, the "actions" panel. This is actually relatively simply, but makes use of the GridBagLayout and the properties of it's constraints to do the whole thing in a single layout

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);
    }

}

Putting it all together

This then simply puts all the separate elements together into a single layout

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);
    }

}

    }
}

回答2:


It, unfortunately, has a bad rap around these parts, but Netbeans' GUI Builder is great for this kind of project. The GUI in this image took me about five minutes to build:

I actually recorded a video of it, but the video did not turn out well because I'm too cheap to pay for good screen recording software. Anyways, I recommend Netbeans GUI Builder. The learning curve is not steep at all (especially compared to handwritten layout managers) and it can do pretty much anything any other layout manager can do, and much quicker.

Below is the code that this generated, but I strongly recommend doing it yourself because Netbeans also generates an .xml file that is vital to the proper functioning of the GUI Builder. And if you want to make changes in the future, you'll need the GUI Builder to do so (one of the drawbacks, but to me it's minor).
