JApplet ,JScrollPane, JPanel
Hi,
I have a class JTestPanel2 which extends JPanel, I have added a button to this class and overriden the paint method to draw some lines,
In my JApplet, i create instance of Test class and add to the JSCrollPane, I add this JScrollPane to my JApplet content pane, the problem is i dont see the JButton on the screen , but when i click on some where i have added the JButton , i get the action performed event triggered,
My layout for Test class is BorderLayout and i add the button to north,
So what is the problem ..how can i solve it,
Answere ASAP
here is the code
for JPAnel
//**************
import java.awt.*;
import javax.swing.*;
import java.awt.event.*;
public class JPanelTest2 extends JPanel implements ActionListener
{
JPanel jp2 ;
JButton jb;
String message = "test";
JPanelTest2()
{
super();
setLayout(new BorderLayout());
jp2 = new JPanel();
jb = new JButton("Okay");
jb.addActionListener(this);
jp2.add(jb);
setPreferredSize(new Dimension(400,400));
add("North", jp2);
jp2.setVisible(true);
}
