JApplet class in Applet
|
As we
prefer Swing to AWT. Now we can use JApplet that can have all the controls of
swing. The JApplet class extends the Applet class.
|
Example of EventHandling in JApplet:
1. import java.applet.*;
2. import javax.swing.*;
3. import java.awt.event.*;
4. public class EventJApplet extends JApplet implements ActionListener{
5. JButton b;
6. JTextField tf;
7. public void init(){
8.
9. tf=new JTextField();
10. tf.setBounds(30,40,150,20);
11.
12. b=new JButton("Click");
13. b.setBounds(80,150,70,40);
14.
15. add(b);add(tf);
16. b.addActionListener(this);
17.
18. setLayout(null);
19. }
20.
21. public void actionPerformed(ActionEvent e){
22. tf.setText("Welcome");
23. }
24. }
|
In
the above example, we have created all the controls in init() method because
it is invoked only once.
