TREE STRUCTURE. So can you explain me why Timer extends EventDispatcher. Can you imagine TREE STRUCTURE of  > Timers??? You lost me. Timer uses EventDispatcher so that it can dispatch timer events. There is no implication of any structure. There are certainly features of EventDispatcher that are not used by Timer, but there is no cost, and I'd much prefer inheritance over a mixin. Adding dispatcher capabilities via composition would be more costly for both memory and performance. If you see only 2 solutions: inheritance and mixin it’s your problem. There are better solutions. EventDispatcher has spare functionality and it’s bad design. >.1.       It's based on string identifiers. Because of this > a.        It's slow Do you have any evidence to back that up? Strings are convenient for a number of reasons. In particular for debugging.             I sad that I can describe better solution if you will be open for discussion. > b.       You don't know for real types of events that object can dispatch. I agree with that. In my own code, I keep constants on the class that does the dispatching, rather than event class. However, it isn't always so straightforward - for example where events can bubble, the events that an object can dispatch are based on what children are added at runtime. 1-0 > c.       You can't use code-inside in editor for access events. I don't know what you mean here... I mean that you can’t press ctrl+space and see events (in outline, like properties and functions) . Sure you can use Flex “Metadata” keywords do describe events dispatched by class and editor will understand them but it’s not a solution it’s a kind of crutches cause in AS3 we don’t have real metadata. (like metadata in C# or annotations in Java) Max Peter On 4/6/06, Maxym <[EMAIL PROTECTED]> wrote: Yeah, I can.
