Regarding use of a wizard in a swing application

Question

I am using the code given here to create my own wizard application.

The basic motive of moving from 1 screen to other is achieved with this. But now I am stuck at a point. The problem is... suppose I have entered some value on screen1 and then I move to screen2.. and on basis of values entered in screen1 I have to display some values on screen 2.. how do I get the values set in screen1 in screen2 using the same code given in the link.

I tried to study the code in detail, but couldn't understand as am fairly new to Java and also to Swing.

If someone has already used the same code to implement wizards, please do help me.

Answer 1

You should store the state of your wizard in the WizardModel, and add getters and setters (i.e. like a JavaBean) appropriately. For example:

public class WizardModel {
   ...
   private String host;

   public void setHost(String host) {
       this.host = host;
   }

   public String getHost() {
       return host;
   }
}

Answer 2

Mr Potato Head (?) is right; the Model is where your data is stored.

For example code you may wish to look at Freedom for Media in Java which seems to have an implementation of WizardModel in the Documentation / Javadoc section, package net.sf.fmj.ui.wizard.

If you wish to have some more examples of Swing applications, and nicely layed-out forms, have a look at JGoodies. Even if you decide not to use their library the examples provided are worth reading.
