[fusion-users] Fusion classes and operability.

[Mike Adair]

Tomas,

There is some documentation on using/extending Fusion events on the 
wiki: http://trac.osgeo.org/fusion/wiki/Cookbook/Fusion/Events

For your other question, I think you are asking about 2 different widget 
instances that inherit from the same base class, sharing some form of 
storage defined in the base class? If so, you may be able to use 
JavaScript closures? http://www.jibbering.com/faq/faq_notes/closures.html
