Im reading the User Guide trying to understand this :
a.) The example references a constructor method. So one new to ExtJs would logically infer there is some construction responsibilities associated with and provided by the class sytem that I am getting by creating a class this way. The presence of a constructor normally would infer that there is a corresponding destruction semantic.
After all we are talking about a 'Class System' here. Initialization and Destruction have high semantic value in the context of a 'Class System'. So it's logical to assume that there are some hooks in the class system that manage this for the class that I am creating.
Imagine my surprise that the 'user guide' doesn't delve into this topic. So I thought, hmm... since the example code doesn't extend from another class explicitly the important concept of initialization and destruction must be a responsibility of the Ext.Base class. Guess What ! It's not even mentioned there. Hmm....
I have one question , if I"m going to be surprised and confused on such a basic aspect of a 'Class System' as managing the initialization and destruction of an instance how am I going to learn ExtJs ? I can't think of a more central concept to a class system as managing the initialization and destruction of instances.
I'm sorry but the user guide is kind of bizarre . So Ext.Base the api doc's don't deal with this topic and that is the foundation of the ExtJS class system ?
I'm confused already ? Does this system support a destructor or not ? Just a constructor ? Do you have to use 'constructor' ? I'm just guessing that you do. I honestly have no idea, i guess I have to comb through your source code. I thought i was looking at a 'System' ?
This does not look 'System-atic' to me at all.
Sorry for the rant... ( i'm sure there is a lot of cool stuff in ExtJS and engineers sometimes don't possess the best skill for teaching things )
