[flexcoders] Re: Custom event & inheritance
Hi, and thanks so far. Obviusly, event inheritance does not work the way I described. What I really wanted to know was that "[Event] metadata should be inherited by the subclasses", not needing to do anything else to use an inherited event in a subclass. So now 'it's time for something completely different', meaning, the event inheritance must be done another way. Thanks for the information! Satu Yahoo!

RE: [flexcoders] Re: Custom event & inheritance
You manipulated the prototype? As in you worked
on A.prototype…? I can’t see how that would work in MXML and do
the right thing. In order to understand the attribute we need to see the
[Event] metadata on the class definition, this means having access to the
source. Assuming you do have access to the source your [Event] metadata should
be inherited by the subclasses. It’s sounding like that’s not
happening for you. I think we’ll need to see a working (or I guess in
this case non-working) example, not just pseudocode to see if we can figure out
what’s going on.

event & inheritance
Hello,
I already commented this but the message appears
to have
disappeared - another try.
Explanation:
In the Application AS file, the prototype of a
standard class A is
manipulated so that the class has event E. The
event is dispatched
with "this.dispatchEvent({target:this,type:"E",...});
Now if I specify an event handler in an MXML file
like
E="doSomething()"/>, everything works
just fine.
But: I also want to use class B which extends
class C extending
class A, ie. B is a subclass of A. If I write like
before
id="id"
E="doSomethingElse()"/>, the compiler says that the E
attribute is unknown.
So, this E event has to be declared all over again
for class B??
What exactly does this mean?
