The only time I really use watch is when extending the MovieClip class and have
a need to know when a built-in property changes,
like MovieClip.enabled
class Comp extends MovieClip {
private var __enabled:Boolean = true;
function Comp {
watch("enabled", setEnabled);
}
private function setEnabled(prop:String, oldVal:Boolean,
newVal:Boolean):Boolean {
__enabled = newVal;
// do some stuff when enabled changed
return newVal;
}
}
