Here's here's one way I might do this:
public function setViewState(state:String):void
{
//Sets parent's view state
this.currentState = state;
// The parent is responsible for controlling its child
// component view states. All components must implement
// IView's setViewState() and all components must define
// view states that match their parents' view states.
// That way, all child components will be updated based
// on the parent's view state.
// I only go down to grandchildren because that's typically
// as deep as I'll make the child component heirarchy.
// But...you never know. So... TODO: Make recursive.
var children:Array=this.getChildren();
for (var i:String in children)
{
if (children[i].hasOwnProperty("setViewState"))
children[i].setViewState(this.currentState);
else {
Alert.show(children[i].toString());
var grandchildren:Array = Container(children
[i]).getChildren();
for (var j:String in grandchildren)
{
if (grandchildren[j].hasOwnProperty
("setViewState"))
grandchildren[j].setViewState
(this.currentState);
}
}
}
}
It needs to be recursive, but maybe there's a better way?
