    I am starting off on Hillegass book, and he talks about the "event queue". From the apple docs, some terms then a question.


    How much of this is just of interest, and how much should one know in detail? So, for example, is the window server a conceptual representation of low level code, or does it really exist as an entity one can see in Xcode, for example? The same would apply to the terms "event loop" and "event port". Is it important, for example, to know which "event port" is being used, or how to find it or which "event manager" is currently active?

    Sorry about the generality of this question, but often, on starting out, it 's nice to know the depth to which one should be looking, or just accept things as is for the time being.

    If you are just starting out, don't worry about it. In objective-c you send messages ([entity message]), which finds its way through the chain, until it reaches something that can respond to it.
    Start worrying about it when you start using menuitems, IBAction's and the first responder chain.
