如何更改 Netbeans 中的 Swing 外观

Question

我是 netbeans ide 的新手，我有一个 swing 桌面应用程序，我想将默认的 java 外观和感觉（为其）更改为物质外观和感觉（或其他），那么如何将物质 jar 文件添加到我的项目中 （我想将项目部署到 jar 文件），并从中设置外观。

谢谢

首先尝试此代码：

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

public class Test extends JFrame {
public Test() {
    initComponents();
}

private void initComponents() {
    // JFormDesigner - Component initialization - DO NOT MODIFY  //GEN-BEGIN:initComponents
    menuBar1 = new JMenuBar();
    menu1 = new JMenu();
    menuItem5 = new JMenuItem();
    menuItem4 = new JMenuItem();
    checkBoxMenuItem1 = new JCheckBoxMenuItem();
    menuItem3 = new JMenuItem();
    menu2 = new JMenu();
    menuItem6 = new JMenuItem();
    tabbedPane1 = new JTabbedPane();
    panel1 = new JPanel();
    scrollPane1 = new JScrollPane();
    textPane1 = new JTextPane();
    button1 = new JButton();
    button2 = new JButton();
    button3 = new JButton();
    scrollPane2 = new JScrollPane();
    textArea1 = new JTextArea();
    scrollPane3 = new JScrollPane();
    tree1 = new JTree();
    progressBar1 = new JProgressBar();
    radioButton1 = new JRadioButton();
    checkBox1 = new JCheckBox();
    panel2 = new JPanel();
    panel3 = new JPanel();

    Container contentPane = getContentPane();
    contentPane.setLayout(null);
    {
        {
            menu1.setText("text");
            menuItem5.setText("text");
            menu1.add(menuItem5);
            menuItem4.setText("text");
            menu1.add(menuItem4);
            menu1.addSeparator();
            checkBoxMenuItem1.setText("text");
            menu1.add(checkBoxMenuItem1);
            menuItem3.setText("text");
            menu1.add(menuItem3);
        }
        menuBar1.add(menu1);
        {
            menu2.setText("text");
            menuItem6.setText("text");
            menu2.add(menuItem6);
        }
        menuBar1.add(menu2);
    }
    setJMenuBar(menuBar1);
    {

        {
            panel1.setLayout(null);

            {
                scrollPane1.setViewportView(textPane1);
            }
            panel1.add(scrollPane1);
            scrollPane1.setBounds(15, 15, 665, scrollPane1.getPreferredSize().height);
            button1.setText("text");
            panel1.add(button1);
            button1.setBounds(15, 45, 300, button1.getPreferredSize().height);
            button2.setText("text");
            panel1.add(button2);
            button2.setBounds(325, 45, 140, 23);
            button3.setText("text");
            panel1.add(button3);
            button3.setBounds(470, 45, 210, 23);
            {
                scrollPane2.setViewportView(textArea1);
            }
            panel1.add(scrollPane2);
            scrollPane2.setBounds(15, 75, 665, 175);
            {
                scrollPane3.setViewportView(tree1);
            }
            panel1.add(scrollPane3);
            scrollPane3.setBounds(15, 260, 140, 150);
            progressBar1.setValue(40);
            panel1.add(progressBar1);
            progressBar1.setBounds(160, 260, 520, 20);
            radioButton1.setText("text");
            panel1.add(radioButton1);
            radioButton1.setBounds(160, 290, 100, radioButton1.getPreferredSize().height);
            checkBox1.setText("text");
            panel1.add(checkBox1);
            checkBox1.setBounds(265, 295, 165, checkBox1.getPreferredSize().height);

            {
                Dimension preferredSize = new Dimension();
                for(int i = 0; i < panel1.getComponentCount(); i++) {
                    Rectangle bounds = panel1.getComponent(i).getBounds();
                    preferredSize.width = Math.max(bounds.x + bounds.width, preferredSize.width);
                    preferredSize.height = Math.max(bounds.y + bounds.height, preferredSize.height);
                }
                Insets insets = panel1.getInsets();
                preferredSize.width += insets.right;
                preferredSize.height += insets.bottom;
                panel1.setMinimumSize(preferredSize);
                panel1.setPreferredSize(preferredSize);
            }
        }
        tabbedPane1.addTab("text", panel1);
        {
            panel2.setLayout(null);

            {
                Dimension preferredSize = new Dimension();
                for(int i = 0; i < panel2.getComponentCount(); i++) {

                    preferredSize.width = Math.max(bounds.x + bounds.width, preferredSize.width);
                    preferredSize.height = Math.max(bounds.y + bounds.height, preferredSize.height);
                }

                panel2.setMinimumSize(preferredSize);
                panel2.setPreferredSize(preferredSize);
            }
        }
        tabbedPane1.addTab("text", panel2);

        {
            panel3.setLayout(null);

            {
                Dimension preferredSize = new Dimension();
                for(int i = 0; i < panel3.getComponentCount(); i++) {
                    Rectangle bounds = panel3.getComponent(i).getBounds();
                    preferredSize.width = Math.max(bounds.x + bounds.width, preferredSize.width);
                    preferredSize.height = Math.max(bounds.y + bounds.height, preferredSize.height);
                }
                Insets insets = panel3.getInsets();
                preferredSize.width += insets.right;
                preferredSize.height += insets.bottom;
                panel3.setMinimumSize(preferredSize);
                panel3.setPreferredSize(preferredSize);
            }
        }
        tabbedPane1.addTab("text", panel3);

    }
    contentPane.add(tabbedPane1);
    tabbedPane1.setBounds(10, 10, 700, 450);

    {
        Dimension preferredSize = new Dimension();
        for(int i = 0; i < contentPane.getComponentCount(); i++) {
            Rectangle bounds = contentPane.getComponent(i).getBounds();
            preferredSize.width = Math.max(bounds.x + bounds.width, preferredSize.width);

    }
    pack();
    setLocationRelativeTo(getOwner());

}

private JMenuBar menuBar1;
private JMenu menu1;
private JMenuItem menuItem5;
private JMenuItem menuItem4;
private JCheckBoxMenuItem checkBoxMenuItem1;
private JMenuItem menuItem3;
private JMenu menu2;
private JMenuItem menuItem6;
private JTabbedPane tabbedPane1;
private JPanel panel1;
private JScrollPane scrollPane1;
private JTextPane textPane1;
private JButton button1;

private JScrollPane scrollPane2;
private JTextArea textArea1;
private JScrollPane scrollPane3;
private JTree tree1;
private JProgressBar progressBar1;
private JRadioButton radioButton1;
private JCheckBox checkBox1;
private JPanel panel2;
private JPanel panel3;

public static void main(String args[]){

    new Test().setVisible(true);


  }
}

您还可以使用 Nimbus 主题，修改为此代码：

try{
        UIManager.setLookAndFeel("com.sun.java.swing.plaf.nimbus.NimbusLookAndFeel");

    }
    catch(Exception e){
        System.out.println("Nimbus isn't available");
    }

并为此编辑主项目：

public static void main(String args[]){

    try{
          UIManager.setLookAndFeel("com.sun.java.swing.plaf.nimbus.NimbusLookAndFeel");

    }
    catch(Exception e){
        System.out.println("Nimbus isn't available");
    }
    new Test().setVisible(true);


}

Answer 2

您可以将 .jar 放置在模块包装器中，就像将任何 .jar 文件放置在 NetBeans 平台应用程序中一样。至于设置外观，您可能需要扩展 ModuleInstall，具体来说，用如下内容重写 returned() 方法：

    try {
      UIManager.setLookAndFeel(new SubstanceRavenGraphiteLookAndFeel());
    } catch (Exception e) {
      System.out.println("Substance Raven Graphite failed to initialize");
    }

Answer 3

抱歉，如果是旧的，但在 Netbeans 上，您可以单击项目上的辅助按钮（右键单击），然后转到“属性”。

接下来转到应用程序>桌面应用程序，您可以在那里更改外观:)。

Answer 4

如果您想在应用程序中使用 Substance LookAndFeel，简单的步骤是将 SubstanceLookAndFeel jar 添加到库类路径中（在 NetBeans IDE 上，只需右键单击库节点，然后添加 Substance.jar）。添加 Substance.jar 后，在主应用程序中只需添加以下代码（在启动主框架之前）：

    public static void main(String[] args) {
    java.awt.EventQueue.invokeLater(new Runnable() {

        @Override
        public void run() {
            try {
                UIManager.setLookAndFeel(new SubstanceLookAndFeel());
            } catch (ClassNotFoundException ex) {
                Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex);
            } catch (InstantiationException ex) {
                Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex);
            } catch (IllegalAccessException ex) {
                Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex);
            } catch (UnsupportedLookAndFeelException ex) {
                Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex);
            }
            new MainFrame();
        }
    });
}

如果您也希望 NetBeans IDE 使用 Substance Look And Feel，只需将 SubstanceLookAndFeel.jar 放在特定目录中（例如，在 /home/ 中） your-username/LAF/SubstanceLookAndFeel.jar) 并使用以下命令启动 NetBeans IDE：

$ netbeans --cp:p /home/your-username/LAF/SubstanceLookAndFeel.jar --laf org.jvnet.substance.SubstanceLookAndFeel
