Unhappy Help with Panels in Java please.


What i want to do is move from one frame to another like when you install a new software and you click on the next button. I am currently using an abstract class and override my drawPanel in each class that follows. The code that i have now is:

import javax.swing.*;

public abstract class Abs{
public abstract JPanel drawPanel();
}

AND


private JFrame frame;

SecondPage sp = new SecondPage(frame);

public FirstPage(JFrame f){
frame = f;
panel = new JPanel();
next = new JButton("Next");
pre = new JButton("Pre");
ActionListener nextL = new NextListener();
next.addActionListener(nextL);
}

public JPanel drawPanel(){

panel.add(pre);
panel.add(next);
return panel;
}

public class NextListener implements ActionListener{
public void actionPerformed(ActionEvent event){
frame.add(sp.drawPanel());
System.out.println("First Page Listener Next");
}
}
}


So can someone plaese help me or provide me with some source code to do this?

Thank You
Diederick

Hi -

This might be of interest:
http://java.sun.com/developer/techni.../swing/wizard/

Before you go that far, I'd definitely make sure you're comfortable programming a basic JFrame, first. Specifically:

1. Create a JFrame with a panel (for example, a scrollable text area) and a couple of buttons (for example, "Do Something" and "Quit")

2. Successfully lay out the controls on the JFrame (for example, change the default JFrame layout manager to a vertical BoxLayout, position the panel on the top, and center the buttons horizontall on the bottom).

3. Successfully display the JFrame (and the attached controls).

4. Successfully field events from the controls (for example, detect button clicks; handle "X" exit)

If you're unclear about any of these "basics", trying working through the Swing tutorials on http://java.sun.com.

You might also want to check out JavaRanch as another resource (in addition to LQ.org):

'Hope that helps .. PSM
