In AS3 and JS (not UnityScript) I'm accustom to the concept of Event Bubbling. In essence, if I have a container with say 20 buttons, it is better to have a listener on the container as opposed to each button (1 listener vs. 20). The container is able to determine which child button was clicked via event bubbling.
I'm curious if something similar can be achieved in tk2d? I have a container GameObject with a tk2dUIItem attached. Within this container I have 20 buttons who currently each have tk2dUIItem components. I have the container capturing events via the Register Events From Children checkbox. My question is, is it possible for a container object (parent) to determine the child that was clicked within? If so, what part of the tk2d API do I need to be using (or look into more). Is there another way to achieve this?
