如何在菜单栏中导入图像 [英] How to import an image in menu bar

问题描述

我创建了一个简单的菜单栏，我不知道如何在可用空间中导入图像。

我的代码如下：

  import java.awt.event。*; 
 import java.awt。*; 
 import javax.swing。*; 
 import java.io.IOException; 
 
公共类MyMenu扩展JFrame {
 
 JMenuBar菜单栏; 
 JMenu文件，编辑，联系，退出; 
 JMenuItem退出，打开，搜索，删除，注册，信息; 
 
 public MyMenu（）{
 setLayout（new FlowLayout（））; 
 // ___________________________ FILE __________________________________ 
 menubar = new JMenuBar（）; 
 setJMenuBar（menubar）; 
 file = new JMenu（Αρχείο）; 
 menubar.add（file）; 
 open = new JMenuItem（Άνοιγμαπελατολογίου）; 
 file.add（open）; 
 event e1 = new event（）; //编译器错误
 open.addActionListener（e1）; 
 // __________________________________编辑____________________________ 
 edit = new JMenu（Ενέργειες）; 
 menubar.add（编辑）; 
 search = new JMenuItem（Αναζήτηση）; 
 edit.add（搜索）; 
 registration = new JMenuItem（Καταχώρηση）; 
 edit.add（注册）; 
 delete = new JMenuItem（Διαγραφή）; 
 edit.add（删除）; 
 // _________________________________联系__________________________ 
 contact = new JMenu（Επικοινωνία）; 
 menubar.add（联系方式）; 
 informations = new JMenuItem（Πληροφορίες）; 
 contact.add（信息）; 
 // ___________________________________ QUIT_____________________________ 
 quit = new JMenu（Έξοδος）; 
 menubar.add（退出）; 
 exit = new JMenuItem（Έξοδος）; 
 quit.add（退出）; 
 event e = new event（）; //编译器错误
 exit.addActionListener（e）; 
} 
 
公共类MyEvent实现ActionListener {
 
 public void actionPerformed（ActionEvent e）{
 System.exit（0）; 
} 
 
 public void actionPerformed2（ActionEvent e1）{
 final SimpleTableDemo a = new SimpleTableDemo（）; //编译错误
 javax.swing.SwingUtilities.invokeLater（new Runnable（）{
 
 public void run（）{
 a.createAndShowGUI（）; 
} 
}）; 
} 
} 
 
 public static void main（String [] args）抛出IOException {
 MyMenu gui = new MyMenu（）; 
 gui.getContentPane（）。add（panel）; //编译器错误
 gui.setDefaultCloseOperation（JFrame.EXIT_ON_CLOSE）; 
 gui.setSize（2400,1900）; 
 gui.setVisible（true）; 
} 
} 
  

它与班级面板？如何利用可用空间并使用图像？

解决方案

请在此处发布可从Java Compilator无错误运行的代码（在 JMenuBar //编译器错误标记>

I've created a simple menu bar and I don't know how to import an image in the free space.

My code is below:

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

public class MyMenu extends JFrame {

    JMenuBar menubar;
    JMenu file, edit, contact, quit;
    JMenuItem exit, open, search, delete, registration, informations;

    public MyMenu() {
        setLayout(new FlowLayout());
        //___________________________ FILE __________________________________
        menubar = new JMenuBar();
        setJMenuBar(menubar);
        file = new JMenu("Αρχείο");
        menubar.add(file);
        open = new JMenuItem("Άνοιγμα πελατολογίου");
        file.add(open);
        event e1 = new event(); // Compiler Error
        open.addActionListener(e1);
        //__________________________________ EDIT ____________________________
        edit = new JMenu("Ενέργειες");
        menubar.add(edit);
        search = new JMenuItem("Αναζήτηση");
        edit.add(search);
        registration = new JMenuItem("Καταχώρηση");
        edit.add(registration);
        delete = new JMenuItem("Διαγραφή");
        edit.add(delete);
        //_________________________________ CONTACT __________________________
        contact = new JMenu("Επικοινωνία");
        menubar.add(contact);
        informations = new JMenuItem("Πληροφορίες");
        contact.add(informations);
        //___________________________________QUIT_____________________________
        quit = new JMenu("Έξοδος");
        menubar.add(quit);
        exit = new JMenuItem("Έξοδος");
        quit.add(exit);
        event e = new event(); // Compiler Error
        exit.addActionListener(e);
    }

    public class MyEvent implements ActionListener {

        public void actionPerformed(ActionEvent e) {
            System.exit(0);
        }

        public void actionPerformed2(ActionEvent e1) {
            final SimpleTableDemo a = new SimpleTableDemo(); // Compiler Error
            javax.swing.SwingUtilities.invokeLater(new Runnable() {

                public void run() {
                    a.createAndShowGUI();
                }
            });
        }
    }

    public static void main(String[] args) throws IOException {
        MyMenu gui = new MyMenu();
        gui.getContentPane().add(panel); // Compiler Error
        gui.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        gui.setSize(2400, 1900);
        gui.setVisible(true);
    }
}

It is related to the class Panel? How can I take advantage of the free space and use an image?

解决方案

please post here Runnable code without Errors from Java Compilator (marked in you code with // Compiler Error) before any of your request for AddingImage / ImportImage in JMenuBar

required tutorials

1) JMenu, JMenuBar, JMenuItems

2) Laying Out Components Within a Container

3) How to Write an Action Listener

4) How to Use Icons

5) and finally for set Image as JMenuBar BackGround you have to read something about 2D Graphics

6) examples on this forum, here or here
