The best way I think is first starting with http://extjs.com/learn/Tutorial:Introduction_to_Ext_2.0 General concepts of data handling (Stores, Proxies, Readers, etc) are here http://extjs.com/learn/Manual:Data and when you got through all of that the API documentation at http://extjs.com/deploy/dev/docs/ is not that frightening any more :) For example it will be clear that JsonStore is just a Store with a reader that knows how to read JSON. You could write your Store and Reader by yourself but since it's such a common case you have JsonStore for convenience. There is of course a learning curve but in this case I think it's fully justified because the design is great with several (necessary) layers of abstraction. More layers, more learning, but it pays off. The alternative would be a "It's so easy to use" framework with no abstraction at all but that would not scale and would be difficult to maintain. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "TurboGears Trunk" group.
