>>" But all those things I can do with normal events, I guess. So my wordplay aside, given my example, you would not use a "normal event" for this type of thing (having a class check data states and broadcast a notification to any listening classes that a certain data state, i.e. the machine is in the "on" state because all levers are pulled) - what kind of "normal" event are you thinking of? I'm wondering if you're thinking of a tight-coupled relationship between classes where every time a lever is pulled, you check to see if all other levers are also pulled and then tell the lightbulb class to light up - that's not a good way to do it, it creates hard (i.e. tightly coupled) dependencies between classes. I would instead do as in my example, broadcast that a certain state of the data (all levers pulled) has been achieved. Then ANY other class, (i.e. the lightbulb, the Wonky Widget, the Funky Fan Button, etc.) can listen and react to that state of the levers. As you code, you want to loosely or completely de-couple relationships as m! uch as possible - depending on the size of the project, the larger the size and complexity, the more you will benefit from doing this.

Maybe I am slow... or even dumb? But all those things I can do with normal events, I guess. So what I mean was an example of something you cannot do with normal event or what is specific case for using a custom event?
