问题描述

在netbeans中创建一个新项目时,如果我选择JAVA Desktop应用程序,它会创建一些我根本无法识别的代码,就像我在摇摆中学到的那样。

When creating a new project in netbeans, if i select JAVA Desktop application, it creates some code which I DO NOT RECOGNISE AT ALL as what i had learnt in swing.

它导入包,例如:

org.jdesktop.application.SingleFrameApplication;

此外,main()的声明如下:

also, the declaration for main() looks like this :

public static void main(String[] args) {
            launch(DesktopApplication2.class, args);
        }

这对我对JFrame,JPanel等的了解毫无意义。 。

This really does not make any sense to my knowledge of JFrame, JPanel etc..

如果我尝试从头编写netbeans应用程序,我可以编写自己的swing应用程序,但我找不到GUI编辑器。

If i try to code a netbeans application from scratch, i can write my own swing app BUT I CANNOT FIND THE GUI EDITOR.


  • 从头开始创建Java应用程序时如何使用GUI编辑器?

  • 任何人都可以向我解释这个org.jdesktop.application .SingleFrameApplication和其他类?

请帮忙。这真是令人沮丧。

Please help. This is really frustrating.

推荐答案

您可能无意中选择了 Java桌面应用程序


基于 Swing应用程序框架(JSR 296)。此模板提供基本的应用程序基础结构,例如菜单栏,窗口状态的持久性和状态栏。使用此模板,您还可以生成代码以创建数据库表的GUI界面。

Creates a skeleton of a desktop application based on the Swing Application Framework (JSR 296). This template provides basic application infrastructure such as a menu bar, persisting of window state, and status bar. With this template, you can also generate code to create a GUI interface for a database table.

而不是 Java应用程序


在标准IDE项目中创建新的Java SE应用程序。您还可以在项目中生成主类。标准项目使用IDE生成的Ant构建脚本来构建,运行和调试项目。

Creates a new Java SE application in a standard IDE project. You can also generate a main class in the project. Standard projects use an IDE-generated Ant build script to build, run, and debug your project.

附录:使用文件>新文件> Java GUI Forms 添加高级容器,例如一个封闭的 JPanel ,可以从 main()实现 run()方法。

Addendum: Use File > New File > Java GUI Forms to add high-level containers, e.g. an enclosing JPanel, that can be instantiated from main()'s run() method.

例如, Main.main()

package temp;
import java.awt.EventQueue;
import javax.swing.JFrame;

public class Main {
    public static void main(String[] args) {
        EventQueue.invokeLater(new Runnable() {
            @Override
            public void run() {
                JFrame f = new JFrame();
                f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
                f.add(new NewJPanel());
                f.pack();
                f.setVisible(true);
            }
        });
    }
}

以及 NewJPanel 在GUI编辑器中构建(注意Generated Code):

And a NewJPanel built in the GUI editor (note "Generated Code"):

package temp;
public class NewJPanel extends javax.swing.JPanel {

    /** Creates new form NewJPanel */
    public NewJPanel() {
        initComponents();
    }

    @SuppressWarnings("unchecked")
    // <editor-fold defaultstate="collapsed" desc="Generated Code">
    private void initComponents() {

        jLabel1 = new javax.swing.JLabel();

        jLabel1.setText("Hello, world!");

        org.jdesktop.layout.GroupLayout layout =
            new org.jdesktop.layout.GroupLayout(this);
        this.setLayout(layout);
        layout.setHorizontalGroup(
            layout.createParallelGroup(org.jdesktop.layout.GroupLayout.LEADING)
            .add(layout.createSequentialGroup()
                .add(163, 163, 163)
                .add(jLabel1)
                .addContainerGap(157, Short.MAX_VALUE))
        );
        layout.setVerticalGroup(
            layout.createParallelGroup(org.jdesktop.layout.GroupLayout.LEADING)
            .add(layout.createSequentialGroup()
                .add(113, 113, 113)
                .add(jLabel1)
                .addContainerGap(171, Short.MAX_VALUE))
        );
    }// </editor-fold>

    // Variables declaration - do not modify
    private javax.swing.JLabel jLabel1;
    // End of variables declaration
 }
