Thread: press a button, get textfield content

Hello chopficaro.

Welcome to the Java Programming Forums.

I wrote you this example code to look at. I hope it helps

import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JButton;
import javax.swing.JTextField;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JOptionPane;
 
public class Chopficaro extends JPanel {
 
	public Chopficaro(){
 
		final JTextField txt = new JTextField("Java Programming Forums");
		txt.setBounds(1, 1, 300, 30);
 
		JButton button = new JButton(" >> CLICK ME <<");
		button.setBounds(40, 40, 200, 40);
 
		setLayout(null);
		add(txt);
		add(button);
 
		[B]// Add action listener to button[/B]
[B]		button.addActionListener(new ActionListener() {
			public void actionPerformed(ActionEvent e) {
 
				// Execute when button is pressed
				//System.out.println("You clicked the button");
 
				String getTxt = txt.getText();
 
				int messageType = JOptionPane.PLAIN_MESSAGE;
 
				JOptionPane.showMessageDialog(null, getTxt, "Java Programming Forums!!", messageType);
			}
		});[/B]
 
	}
 
	public static void main(String[] args) {
 
		JFrame frame1 = new JFrame("JavaProgrammingForums.com");
		frame1.getContentPane().add(new Chopficaro());
 
		frame1.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		frame1.setSize(310, 130);
		frame1.setVisible(true);
	}
 
}

Output:



As you can see, the text in the JTextField is displayed in the popup when you click the button.
