I don't get the point as there seems to be an answer to this question ot available on the Forum.

Anyway
Use a Factory !
Your problem is simply a variation on the Singelton pattern (Simple variationof the Factory Patterns). I believe you should search for it & then repost if you cannot solve some of the details.

A famous reference about it is th GoF book ("Design Patterns - Element of Software reusable Object - Oriented Software").

Otherwise : http://www.artima.com/designtechniques/booklist.html

I thought Bill had written one (see bottom of the page)...
Works in Progress
The Precise Object: Best Practices in Object-Oriented Design with Java
Bill Venners
This work-in-progress is one of my current writing projects.

Hey Thomas

You seem like you know alot your the only one answering questions instead of posting them up!!

i was wondering i u could tell me about JComboBoxes

i have tried changing the colors associated with this box but i cannot change the colour (blue) that comes up when u select an item, how do u change this colour and the general appearance of the JComboBox, i.e. focus content area filled etc!

thankyou

Just try to explain simply what you want & I'll work on it tomorrow night.

Please keep it simple & provide a little uncertain ideas... One tend to follow others path & do first there mistake !
