Help with calling methods

Posted 24 September 2008 - 10:14 AM

I'm almost finished my project "nText" but I have one problem, I can't seem to call one of the classes. Here is the class that calls the other class:
package texteditor;

import java.awt.*;

public class TextEditor extends javax.swing.JFrame {
    public TextEditor() {
        initComponents();
    }
    
    private void initComponents() {

        jScrollPane3 = new javax.swing.JScrollPane();
        TextArea = new javax.swing.JTextPane();
        jMenuBar1 = new javax.swing.JMenuBar();
        FileMenu = new javax.swing.JMenu();
        MenuItemNew = new javax.swing.JMenuItem();
        MenuItemOpen = new javax.swing.JMenuItem();
        MenuItemSave = new javax.swing.JMenuItem();
        jSeparator1 = new javax.swing.JSeparator();
        manageFiles = new javax.swing.JMenuItem();
        jSeparator2 = new javax.swing.JSeparator();
        jMenuItem2 = new javax.swing.JMenuItem();

        setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);
        setTitle("nText");

        TextArea.setBorder(javax.swing.BorderFactory.createLineBorder(new java.awt.Color(255, 255, 255)));
        jScrollPane3.setViewportView(TextArea);

        FileMenu.setText("File");

        MenuItemNew.setAccelerator(javax.swing.KeyStroke.getKeyStroke(java.awt.event.KeyEvent.VK_N, java.awt.event.InputEvent.CTRL_MASK));
        MenuItemNew.setText("New");
        MenuItemNew.addActionListener(new java.awt.event.ActionListener() {
            public void actionPerformed(java.awt.event.ActionEvent evt) {
                MenuItemNewActionPerformed(evt);
            }
        });
        MenuItemNew.addKeyListener(new java.awt.event.KeyAdapter() {
            public void keyReleased(java.awt.event.KeyEvent evt) {
                MenuItemNewKeyReleased(evt);
            }
        });
        FileMenu.add(MenuItemNew);

        MenuItemOpen.setAccelerator(javax.swing.KeyStroke.getKeyStroke(java.awt.event.KeyEvent.VK_O, java.awt.event.InputEvent.CTRL_MASK));
        MenuItemOpen.setText("Open...");
        MenuItemOpen.addActionListener(new java.awt.event.ActionListener() {
            public void actionPerformed(java.awt.event.ActionEvent evt) {
                MenuItemOpenActionPerformed(evt);
            }
        });
        MenuItemOpen.addKeyListener(new java.awt.event.KeyAdapter() {
            public void keyReleased(java.awt.event.KeyEvent evt) {
                MenuItemOpenKeyReleased(evt);
            }
        });
        FileMenu.add(MenuItemOpen);

        MenuItemSave.setAccelerator(javax.swing.KeyStroke.getKeyStroke(java.awt.event.KeyEvent.VK_S, java.awt.event.InputEvent.CTRL_MASK));
        MenuItemSave.setText("Save");
        MenuItemSave.addActionListener(new java.awt.event.ActionListener() {

        MenuItemSave.addKeyListener(new java.awt.event.KeyAdapter() {
            public void keyReleased(java.awt.event.KeyEvent evt) {
                MenuItemSaveKeyReleased(evt);
            }
        });
        FileMenu.add(MenuItemSave);
        FileMenu.add(jSeparator1);

        manageFiles.setAccelerator(javax.swing.KeyStroke.getKeyStroke(java.awt.event.KeyEvent.VK_M, java.awt.event.InputEvent.CTRL_MASK));
        manageFiles.setText("Manage Files");
        manageFiles.addActionListener(new java.awt.event.ActionListener() {

                manageFilesActionPerformed(evt);
            }
        });
        FileMenu.add(manageFiles);
        FileMenu.add(jSeparator2);

        jMenuItem2.setAccelerator(javax.swing.KeyStroke.getKeyStroke(java.awt.event.KeyEvent.VK_X, java.awt.event.InputEvent.CTRL_MASK));
        jMenuItem2.setText("Exit");
        FileMenu.add(jMenuItem2);

        jMenuBar1.add(FileMenu);

        setJMenuBar(jMenuBar1);

        javax.swing.GroupLayout layout = new javax.swing.GroupLayout(getContentPane());
        getContentPane().setLayout(layout);
        layout.setHorizontalGroup(
            layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)

        );

        pack();
    }

Are you getting any errors? OR is it just not doing anything?

You only specified one constructor that accepts 2 parameters.

java.awt.Frame parent and boolean modal

When you try to call it with no parameters, it does not compile correctly.

Those are in lines 125 and 130, correct? You can't call a constructor that doesn't exist.

Hope this helps! :D

You either pass it the 2 parameters it's looking for, or you create an empty constructor

public WriteFileUI(java.awt.Frame parent, boolean modal) { 
         initComponents();  
}

Here is what he means:
You are calling the 2nd class as follows:
//There is a error here when calling the class:
private void MenuItemSaveActionPerformed(java.awt.event.ActionEvent evt) {
WriteFileUI wFUI = new WriteFileUI();
}

//There is also the same problem here:
private void MenuItemSaveKeyReleased(java.awt.event.KeyEvent evt) {
WriteFileUI sWFUI = new WriteFileUI();
}
But you are not passing any parameters to the class.
The problem is that the class default constructor requires "2" parameters to run.
So, either create another construtor that accepts no parameters or, what I suggest, add the needed parameters to the call. Example:
callClass(paraONE, paraTWO)
Hope this helps.
