Thread: JTextArea addActionListener

I am on the controller side of my application and I am having a issue with adding a actionListener to my JTextArea.

package addItemBtn.Home.DataBase;
 
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
 
import javax.swing.event.DocumentEvent;
import javax.swing.event.DocumentListener;
 
public class AddItemController 
{
	private AddItemModel model;
	private AddItemView view;
 
	AddItemController()
	{
 
		//adding actionListeners for the AddItemClass
		view.cancelBtn.addActionListener(new ActionListeners());
		view.submitBtn.addActionListener(new ActionListeners());
		view.previewBtn.addActionListener(new ActionListeners());
		view.nameBox.addActionListener(new ActionListeners());
		view.priceBox.addActionListener(new ActionListeners());
		view.locationBox.addActionListener(new ActionListeners());
		view.descriptionBox.addActionListener(new ActionListeners());
	}
 
	class ActionListeners implements ActionListener
 
	{
 
		@Override
		public void actionPerformed(ActionEvent e) {
			// TODO Auto-generated method stub
 
		}
 
 
	}
 
}

view.descriptionBox.addActionListener(new ActionListeners());//this is where my error is

Error states: The method addActionListener(AddItemController.ActionListener s) is undefined for the type JTextArea)

I clicked on each of the suggestions it gives me but it is still not working. Another things is I found examples on the web with people using actionListener with JTextArea..... Any advice?

Its simple as that. A JTextArea does not support ActionListeners.
What kind of "Action" should a JTextArea produce in your opinion?
Perhaps you should try with a different listener.

yes I understood the error and and read the API doc and still get the same issue:

package addItemBtn.Home.DataBase;
 
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
 
import javax.swing.event.DocumentEvent;
import javax.swing.event.DocumentListener;
 
 
public class AddItemController 
{
	private AddItemModel model;
	private AddItemView view;
 
	AddItemController(AddItemModel model,AddItemView view)
	{
		this.model = model;
		this.view = view;
 
		//adding actionListeners for the AddItemClass
		view.cancelBtn.addActionListener(new ActionListeners());
		view.submitBtn.addActionListener(new ActionListeners());
		view.previewBtn.addActionListener(new ActionListeners());
		view.nameBox.addActionListener(new ActionListeners());
		view.priceBox.addActionListener(new ActionListeners());
		view.locationBox.addActionListener(new ActionListeners());
		view.descriptionBox.addDocumentListener(new ActionListeners()); //error is here
 
		view.frame.setVisible(true);
	}
 
	class ActionListeners implements ActionListener, DocumentListener
 
	{
 
		@Override
		public void actionPerformed(ActionEvent e) 
		{
			try
			{
				if(e.getSource() == view.submitBtn)
				{
					System.out.println("submit Pressed");
				}
				else if(e.getSource() == view.cancelBtn)
				{
					view.frame.dispose();
					System.out.println("Cancel Pressed");
				}
				else if(e.getSource() == view.previewBtn)
				{
 
				}
				else if(e.getSource() == view.descriptionBox)
				{
 
				}
				else if(e.getSource() == view.nameBox)
				{
 
				}
				else if(e.getSource() == view.priceBox)
				{
 
				}
				else if(e.getSource() == view.locationBox)
				{
 
				}
				else
				{
					System.out.println("else");
				}
 
			}catch(Exception ex)
			{
				System.out.println("There was an error "+e);
			}
 
		}
 
		@Override
		public void insertUpdate(DocumentEvent e) {
			// TODO Auto-generated method stub
 
		}
 
		@Override
		public void removeUpdate(DocumentEvent e) {
			// TODO Auto-generated method stub
 
		}
 
		@Override
		public void changedUpdate(DocumentEvent e) {
			// TODO Auto-generated method stub
 
		}
 
 
	}
 
}

Also my actionListeners are not working. I put println statements in there to double check and nothing it happening.

it is simply a JTextArea from AddItemView()

Review the JTextArea API (near the top) for the technique required to add a document listener. Your existing approach is incorrect.

Thank you. When in doubt read the API.

TextListener!! Says it plan as day...

You're welcome, and that's a good rule to follow.
