ItemListener problem with JComboBox

[al_Marshy_1981]

I cant get to the bottom of this problem. I have an ItemListener on a JComboBox, the problem is whenever I change the item in the list the listener handler class produces two outputs instead of one. It's like it is running the event twice :confused:

The code in red is printed out twice. Thats the problem basically.

Any help apprecitated

import java.awt.GridBagLayout;
import java.awt.event.ItemEvent;
import java.awt.event.ItemListener;

import javax.swing.*;

public class ItemListenerTrouble {

	private JFrame frame;
	private JPanel panel;
	private JComboBox comboBox;
	private String[] words={"hello","goodbye","yes","no"};
	public ItemListenerTrouble()
	{
		frame=new JFrame("Create Your Team");
		frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		frame.setSize(600,400);
		
		panel=new JPanel();
		panel.setLayout(new GridBagLayout());
		
		comboBox=new JComboBox(words);
		ItemHandler ihandle=new ItemHandler();
		comboBox.addItemListener(ihandle);
		
		
		panel.add(comboBox);
		
		frame.getContentPane().add(panel);
		frame.setVisible(true);
	}
	
	private class ItemHandler implements ItemListener
	{

		public void itemStateChanged(ItemEvent event) 
		{
			if(event.getSource().equals(comboBox))
			{
				[COLOR="Red"]System.out.println("hello");[/COLOR]
			}
		}
		
	}
	
	public static void main(String args[])
	{
		new ItemListenerTrouble();
	}
}

I'm no pro at this, but what if you change your listener like so:

  private class ItemHandler implements ItemListener {
    public void itemStateChanged(ItemEvent event) {
      if (event.getSource().equals(comboBox)) {
        if (event.getStateChange() == ItemEvent.SELECTED) {
          System.out.println("hello.  Item Selected: " + comboBox.getSelectedItem());
        }
      }
    }
  }

Brilliant as always Fubarable!! The funny thing is I always used to use .getSelectedItem() when I wanted the a comboBox selection after a button was pressed. First time using the ItemListener. Right back to the project :D

Thanks Fubarable

I wish it were brilliant -- but it's from the tutorial: How to Write an Item Listener (The Java™ Tutorials > Creating a GUI With JFC/Swing > Writing Event Listeners)
