Constructors in Flex when working with Custom Events

[Ravi Kiran Va]

Hi

I am seeing that we can use many constructors when developing a Custom Event
(A class that extends the basic Event class )

For example

public class LoginEvent extends Event 
{

  public function LoginEvent()//// What are the exact parameters required here a
        {
         
        }

}

The query i want to ask is that are there standard paramerized constructor that should be used ??

Please share youy ideas .
Thanks in advanve .
