I want to be able to detect when my button, ever so conveniently named button is clicked, I am having trouble making it be that way. here is some code
import java.awt.GridLayout;
import java.awt.event;
import javax.swing.BorderFactory;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JButton;
public class Main implements ActionListener
//im having immense problems implementing the action listener.
{
public static void main(String[] args)
{
new GUI(); // calling in main.
System.out.print("test for bad wifi because my wifi hates me"); // I'm using a cloud based ide
}
JFrame frame1 = new JFrame();
JPanel panel1 = new JPanel();
JFrame frame2 = new JFrame(); //not in use yet
JPanel panel2 = new JPanel(); //""
public void GUI()
{
JButton button = new JButton("moment");
button.addActionListener(this);
panel1.setBorder(BorderFactory.createEmptyBorder( 30, 30, 30, 30 ));
panel1.setLayout(new GridLayout(0, 1));
panel1.add(button);
frame1.add(panel1, BorderLayout.CENTER); // frame is on the pannel or vice versa
frame1.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); // funny close
frame1.setTitle("Final.");
frame1.pack();
frame1.setVisible(true);
}
@Override
public void actionPerformed(ActionEvent e)
{
}
}
Any help is appreciated
Download and use an IDE.
Oracle has a helpful tutorial, Creating a GUI With JFC/Swing . Skip the Netbeans section.
The JFrame
methods must be called in a specific order. This is the order I use for all my Swing applications.
Here's the complete runnable code I wound up with.
import java.awt.BorderLayout;
import java.awt.GridLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.BorderFactory;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.SwingUtilities;
public class SimpleJButtonExample implements ActionListener {
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
@Override
public void run() {
new SimpleJButtonExample().createAndShowGUI(); // calling in main.
}
});
// I'm using a cloud based ide
System.out.println("test for bad wifi because my wifi hates me");
}
JFrame frame1 = new JFrame();
JPanel panel1 = new JPanel();
JFrame frame2 = new JFrame(); // not in use yet
JPanel panel2 = new JPanel(); // ""
public void createAndShowGUI() {
JButton button = new JButton("moment");
button.addActionListener(this);
panel1.setBorder(BorderFactory.createEmptyBorder(30, 30, 30, 30));
panel1.setLayout(new GridLayout(0, 1));
panel1.add(button);
frame1.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); // funny close
frame1.setTitle("Final");
frame1.add(panel1, BorderLayout.CENTER); // panel is within the frame
frame1.pack();
frame1.setVisible(true);
}
@Override
public void actionPerformed(ActionEvent e) {
System.out.println("Button clicked");
}
}
