new TextFieldAction(): Code that initializes the GUI is written here.
Just type the text and hit enter to change the title because ActionEvent is generated.
import java.awt.*;
import java.awt.event.*;
class TextFieldAction extends Frame
{
TextField t;
public TextFieldAction()
{
createAndShowGUI();
}
private void createAndShowGUI()
{
setTitle("TextField with ActionListener demo");
setLayout(new FlowLayout());
// Create simple TextField that shows 20 chars
t=new TextField(20);
// Add ActionListener
t.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent ae)
{
// Change frame title
setTitle(t.getText());
}
});
// Add the textfield
add(t);
setSize(400,400);
setVisible(true);
}
public static void main(String args[])
{
new TextFieldAction();
}
}
