Event Capture Phase as well as Bubbling Supported?

Both Capture and Bubble Supported?

Do events that propagate through the Kinetic tree support both javascript like Capture Phase as well as Bubbling Phase?

Background for the question:

In javascript events that propagate through the DOM do so in two phases: 1) Capture phase where events propagate downward from the highest parent all the way to the leaf children.

2) Bubbling where events bubble up from the lowest leaf nodes to the highest parent.

Reason for wanting Capture as well as Bubbling:

I am using Kinetic for a robotic modeling and control application. Imagine that you have a robot which is composed of many Kinetic parts. Imagine proximity sensors for example that are oriented on the robot in a particular geometry. Now lets say for example I move the robot:

• I want to fire a custom move event on the robot.
• I want that event to propagate down to the sensors which are instantiated as children on the robot so that they can then interrogate their environment with respect to their current position and determine that state.

cool app!

Currently I do not intend to support the capturing phase. Your use case could be easily handled by listening for an event on a Kinetic Node, and then attaching an event handler that traverses the children and does something with each, like this:

node.getChildren().each(function(child) { // do something with each child, or traverse downwards further });

Yup. Thanks. That is exactly what I did.
