any Design Patterns for Wizzzzzard ?

[Pondy Prem]

I All:
I would like to know whether any design pattern exists for Wizard creation and control

1. What are the collaborating classes ?
2. Who should create the wizard frame ?
3. Who should listen for "Back" "Next" "Cancel" Buttons ?
4. Who should decide what is the next/prev panel to show
5. Who should track the current state of the wizard-process ?

Thank you,
Prem

Hello!
Once I applied "STATE PATTERN" for the same case and was just great. When I had to add more options, just I had to create
another state and that's it.

Thank you monofremix for the info.
I would like to know how to manage the Panels ... in the case where there are multiple-branching-paths based on the options that the user chooses at intermediate screens.
.. and everyscreen need to save/retrieve data from database too (i.e: dynamic ).
I would be glad if you/someone could enlighten me about the responsibility allocation.
Specifically which class will decide about the screen-to-show-next.
Thank you
Prem

Hello Prem
Try with the following:
Use the State Pattern for controling each state [back, next buttons} and a CardLayoutPanel object (for each panel)
Each state will notify the CardLayoutPanel to show the right option
There will be just one panel including the NEXT and BACK button wich implement the ActionListener interface
Check this link for more informatio about this pattern"

This the only help I can give you for now.
