Hello Manish,
-- Casting:
ActionScript does not differ between a Integer or int. However: casting
is possible by using a class as a function:
var foo: Bar = Bar( anything );
or with the "as" keyword
var foo: Bar = anything as Bar;
The difference between the two statements is that Bar(anything) will
throw an error if the types don't match but "as Bar" will return null.
If you have a variable of a dynamic "*" type then it will be
automatically casted:
var anything: * = new Baz();
var foo: Bar = anything; // throws an error if anything isn't of
type Baz
-- Events:
ActionScript implements the ECMAScript event dispatching mechanism [1].
The separation of type (String) and data (Event object) is useful
to pass additional data with it.
-- Function Overloading:
ActionScript does not support parameter overloading. It has been
requested as ASL feature at Adobe [2] But Adobe is very careful not
to change(improve) ActionScript as a language. Aside from that: Method
overloading is a controversial feature anyways.
ALL the questions you've asked are ActionScript specific (not Flex
specific).
yours
Martin.

Hi All,
I am not able to understand that it is a bug or not an issue.
If you know the concept of Casting (in which one object is
being cased in to parent Class) i.e. you can convert *int* into *INTEGER.*
*

Same thing I am going to do with the Event class. In the attached
files I have just dispatch a simple MouseEvent.Click which is cased
into Event but when i run the application it gives a error no Source.
i.e. Can be type casted.
Second thing. I have also apply a add Event Listener in the main file
and Linten a mouse Event and apply a function on it which calls when
the event is being dispatched. In Argument I have pass a Event Class
object.
How's that Possible one side it gives me error and second side it is
working fine.
Please Tell me about this. One more thing I have found the Flex is
not Supported the OOPS concept. i.e. Function Overloading
Thanks & Regards***?*
