Internationalization: Select language from combo box

[alejandrgarcia]

Hi, I'm trying to make the user select the language of a very simple menu.
I post here the 2 classes: Menus and Selector.
In the Menus class, there are 2 items: File and Help
When you click on File then you select Configuration, and it shows the Selector class which is only a ComboBox, where you select the Language.

The Menus class is in part internationalized because I defined a Resources file with this pairs:

TITLE=Internationalization!
FILE=File
HELP=Help
OPEN=Open
CONFIGURATION=Configuration

So that's first step is done, and it works fine, now I need the end user to select the language in the Configuration combo box and on the fly load TITLE, FILE,HELP,OPEN and CONFIGIRATION from an appropiate Resourses_es_ESP.properties file that I've already created, if for example he selects Spanish, that properties file has this pairs:
TITLE=Internationacionalizacion
FILE=Archivo
HELP= Ayuda
OPEN=Abrir
CONFIGURATION=Configuracion.

Any help please?

Here is the menu class just to select the Configuration option:

Code:

import java.awt.event.*;
import java.util.ResourceBundle; 
 
public class Menus extends javax.swing.JFrame
{
 ResourceBundle res = ResourceBundle.getBundle("Resources");
 
  public Menus()
  {
    setSize(500, 300); 
	 String title = res.getString("TITLE");
	  this.setTitle(title); 
    initComponents();  
  }
 
    
  private void initComponents()
  {
    jmbarBarraDeMenus = new javax.swing.JMenuBar();
	 
	 jmnuArchivo = new javax.swing.JMenu();
    String fi = res.getString("FILE"); 
    jmnuArchivo.setText(fi);
	 jmbarBarraDeMenus.add(jmnuArchivo);
	 jmbarBarraDeMenus.add(jmnuArchivo);
	 
	  jmnuHelp = new javax.swing.JMenu();
   	String hel = res.getString("HELP"); 
      jmnuHelp.setText(hel);
	  jmbarBarraDeMenus.add(jmnuHelp);
	 
	  jmnuAbrir = new javax.swing.JMenuItem();
	   String op = res.getString("OPEN"); 
      jmnuAbrir.setText(op);
 
	 
	 jmnuArchivo.add(jmnuAbrir);
 
	 
	 jmnuConfigura = new javax.swing.JMenuItem();
	 String co = res.getString("CONFIGURATION"); 
      jmnuConfigura.setText(co);
	 jmnuArchivo.add(jmnuConfigura);
	 jmnuConfigura.addActionListener(new ActionListener() {
      public void actionPerformed(ActionEvent e) {
        jMenuConf_actionPerformed(e);
      }
    });
 
	 	 
  
     getContentPane().setLayout(null);
      addWindowListener(new java.awt.event.WindowAdapter()
        {
          public void windowClosing(java.awt.event.WindowEvent evt)
            {
          exitForm(evt);
            }
        });		  
   setJMenuBar(jmbarBarraDeMenus);
  }//GEN-END:initComponents
 
  /** Exit the Application */
  private void exitForm(java.awt.event.WindowEvent evt) {
    System.exit (0);
  }
  
  
	
 void jMenuConf_actionPerformed(ActionEvent e) {
     Selector dlg = new Selector();
    dlg.setVisible(true) ;
 
	 
      }
		
	
  public static void main (String args[])
  {
    new Menus().setVisible(true);
  }
 
private javax.swing.JMenuBar jmbarBarraDeMenus;
private javax.swing.JMenu jmnuArchivo;
private javax.swing.JMenu jmnuHelp;
private javax.swing.JMenuItem jmnuAbrir; 
private javax.swing.JMenuItem jmnuConfigura; 
 
  }

And here is the selector it's just a combo box to select the language

Code:

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
 
public class Selector extends javax.swing.JFrame
{
/** Creates new form CAplicación */
private javax.swing.JLabel jEtSaludo;
private javax.swing.JButton jBtSaludo;
  public Selector()      // constructor
  {
    setSize(300, 200);      // tamaño del formulario
    setTitle("Language Selector"); // título del formulario
    initComponents();       // iniciar controles o componentes
  }
 
    private void initComponents()//GEN-BEGIN:initComponents
  {
 
   getContentPane().setLayout(null);
      addWindowListener(new java.awt.event.WindowAdapter()
        {
          public void windowClosing(java.awt.event.WindowEvent evt)
            {
          exitForm(evt);
            }
        });
	 
		 	 
	 String[] langStrings = { "Spanish", "French", "Dutch", "Chinese", "English" };
 
   JComboBox langList = new JComboBox(langStrings);
   langList.setSelectedIndex(4);
   getContentPane().add(langList);
	langList.setBounds(42,90,204,30);
	 		
 
  }//GEN-END:initComponents
 
  /** Exit the Application */
  private void exitForm(java.awt.event.WindowEvent evt) {//GEN-FIRST:event_exitForm
    System.exit (0);
  }//GEN-LAST:event_exitForm
  
  private void langListActionPerformed(java.awt.event.ActionEvent evt)
   {
	 //do something
	 
	     }
  /**
   * @param args the command line arguments
   */
  public static void main (String args[])
  {
    new Selector().setVisible(true);
  }
 
 
}
