With that few nodes, efficiency probably isn't an important consideration. Gordon Smith Adobe Flex SDK Team

So, you're thinking something like this (pseudo-code): for (var i:int = 0; i < this.numChildren; i++) { var child:IPropogatableDisplayObject = this.getChildAt(i) as IPropogatableDisplayObject; if (child) child.handleEvent(myCustomEvent); } Something like that? I guess that would be more efficient... Of course, the nice thing about the event system is that it already had a priority system and default cancelling, which are behaviors that I need as well. Once I rolled that functionality in, do you think this approach would still be significantly more efficient than hijacking the event system? Depth of my tree is 5 to 6 levels, total number of nodes is less than 100, number of events (per node) would be about 10 per frame. Troy.
