In addition, your custom class can take a reference to the main Flex
MXML class and use that to change the state right within the class
(though this is not good encapsulation practice!)
To do that, (and I don't know why I'm recommending it.... bad idea
architecturally...but oh well) you would do:
public class MyClass extends UIComponent
{
public function MyClass(app:UIComponent)
{
var b:Button = new Button();
b.label = "Click me"
b.addEventListener(MouseEvent.CLICK, onClick);
addChild(b);
}
private function onClick():void
{
app.currentState = "myOtherState";
}
}
