I finally succeeded in reading your attachment. You didn't do what I told Ian 
Ropper. The class in your project must be named "ListBox", and be exported, 
so that you overrides the default ListBox class. You are exporting a form of 
your project, which is useless.

I suggest you read the document on the wiki about the Gambas object model. I 
will update it to add more explanation about the Observer class, but 
everything done by this class is explained in its page documentation.
