public variables into components

[SirDuke]

Hi.

I have some variables in my application that i use often and in many custom components. An example you be this:

[Bindable]
private var genderTypes:Array = new Array("Male", "Female");


How can i declare this only once (in my main application) so that i don't have to put this code in all the components that will use it?

If i make it public my components can access it and use it but i get errors at compile time that i want to avoid.

Any ideas?:eek:

Error when you make it public? There must be something else going on there.

If you just have one pice of data, this is a quick solution:

in main application

public const GATEWAY:String = 'http://localhost/gateway.py';


in component

private const myGateWay:String = Application.application.GATEWAY;


Although if you have a collection of related data it would probably be better to put it in a singleton class:

public class AuthUser {

//singleton instance makes sure there is only one instance of AuthUser
static private var myInstance:AuthUser;

//constructor takes an inaccessable class as parameter to force use
//of getInstance() for signleton use
public function AuthUser( singletonEnforcer:SingletonEnforcer ) { }

public static function getInstance():AuthUser {
if( AuthUser.myInstance == null ) {
AuthUser.myInstance = new AuthUser( new SingletonEnforcer() );
}

return AuthUser.myInstance;
}
}

//publicly inacsessable dummy class used to enforce signleton
class SingletonEnforcer { }


This requires the use of the static method getInstance to instantiate which will return a reference to a "global" object that you can access any where in your program.

Like this:

import mypgk.AuthUser;
private var myCurrentUser:AuthUser = AuthUser.getInstance();


Hope this helps a bit,
