RE: [Flashcoders] Setting a property in a class from another class
I think it would be better to loosely couple these two classes instead.
Have class B dispatch a custom event when you want to change the
property in class A. Create a listener in Class A for it. As for the
value, make the value public in class B and when class A hears the
event, grab it, or, pass the value through the event.

Hi,
your class B instance will need a reference to an instance of Class A,
unless your nextPrev property is static.
If nextPrev is static, Class B can do ClassA.nextPrev (assuming the
property
is public).
If nextPrev is not static, you'll need to do new ClassB
(myClassAInstance)
and access the instance of A within B.
Another option is a separate method doSomething (pClassA:ClassA) {
pClassA.nextPrev = whatever; }

Hi,
I have a basic problem that I cant figure out how...
I have a ClassA and ClassB (both extend Sprite)
ClassA has a property called "nextPrev:Boolean"
Inside ClassA I create an instance of ClassB like this:
public var myB:ClassB = new ClassB();
Now, is it possible that I can have a method inside ClassB that can
set the "nextPrev" property inside ClassA?
Dont know if this is possible...

yes, just create a setter method that then calls the method in your
composed class:
public function set nextPrev(np:Boolean):void {
myB.nextPrev = np;
}
public function get nextPrev():Boolean {
return myB.nextPrev;
}

It is possible, you have to override the function in ClassA from within ClassB HTH Regards Cor -Original Message- From: flashcoders-boun...@chattyfig.figleaf.com [mailto:flashcoders-boun...@chattyfig.figleaf.com] On Behalf Of Sajid Saiyed Sent: dinsdag 20 oktober 2009 12:04 To: flashcoders@chattyfig.figleaf.com Subject: [Flashcoders] Setting a property in a class from another class Hi, I have a basic problem that I cant figure out how...
