I having trouble setting up my Action Listeners. This first class, MyFrame, is used to build the components of my UI. The second class, MyMenuBar, is one of those components. Now, I'm trying to set up Action Listeners for the Menu buttons in MyMenuBar and have MyFrame handle the Action Events.
When I compile, I get errors for the two lines in MyMenuBar:
item.addActionListener(this);The errors say "addActionListener(java.awt.event.ActionListener) in javax.swing.AbstractButton cannot be applied to (com.jne.MyMenuBar)"
I need help fixing this problem, I'm not really sure what's wrong. Please note, I've only posted two classes from my program. I can post the rest if needed.
MyFrame.java
CODE
package com.jne;
import java.awt.Container;
import javax.swing.JFrame;
import javax.swing.SwingUtilities;
import java.awt.BorderLayout;
import java.awt.*;
import java.awt.event.ActionListener;
import java.awt.event.ActionEvent;
public class MyFrame extends JFrame implements ActionListener {
MyPanel myPanel;
MyMenuBar myMenuBar;
MyButtons myButtons;
public MyFrame() {
myPanel = new MyPanel();
Container contentPane = this.getContentPane();
contentPane.add(myPanel);
myMenuBar = new MyMenuBar();
this.add(myMenuBar, BorderLayout.PAGE_START);
myButtons = new MyButtons();
this.add(myButtons, BorderLayout.LINE_START);
}
public void actionPerformed(ActionEvent e) {
//JFileChooser fileChooser = new JFileChooser();
if(e.getActionCommand().equals("Open")) {
Toolkit.getDefaultToolkit().beep();
}
else if(e.getActionCommand().equals("Save")) {
Toolkit.getDefaultToolkit().beep();
}
else if(e.getActionCommand().equals("Exit")) {
System.exit(0);
}
else if(e.getActionCommand().equals("Set Width")) {
Toolkit.getDefaultToolkit().beep();
}
else if(e.getActionCommand().equals("Set Indent")) {
Toolkit.getDefaultToolkit().beep();
}
else if(e.getActionCommand().equals("Set Numbering")) {
Toolkit.getDefaultToolkit().beep();
}
}
}
MyMenuBar.java
CODE
package com.jne;
import java.awt.*;
import javax.swing.*;
import java.awt.event.ActionListener;
public class MyMenuBar extends JMenuBar {
MyPanel myPanel = new MyPanel();
String[ ] fileItems = new String[ ] {"Open", "Save", "Exit"};
String[ ] settingsItems = new String[ ] {"Set Width", "Set Indent", "Set Numbering"};
public MyMenuBar() {
JMenu fileMenu = new JMenu("File");
JMenu settingsMenu = new JMenu("Settings");
for(int i = 0; i < fileItems.length; i++) {
JMenuItem item = new JMenuItem(fileItems[i]);
item.addActionListener(this);
fileMenu.add(item);
}
for(int i = 0; i < fileItems.length; i++) {
JMenuItem item = new JMenuItem(settingsItems[i]);
item.addActionListener(this);
settingsMenu.add(item);
}
this.add(fileMenu);
this.add(settingsMenu);
}
}
