[fusion-users] Fusion classes and operability.

[Tómas Guðmundsson]

Thanks mike,

Thanks for that link, I hadn't found it in the cookbook yet. That closures 
thing is also smart but I just took an easy example of containers to refer
my problem to classes. In general coding sense I am thinking of a static 
class that is initiated by Fusion and accessible to all other classes 
(widgets). Just like the function "this.getMap()" is accessible to all.

Regards,
Tómas.

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
