This sounds right.

If you are implementing an atk object class for EIconBarItem can you implement 
AtkAction on that object.

This would mean that you do not expose children for that object but implement 
AtkImage to expose the image and AtrkText to expose the text. This sounds 
similar to a GtkButton.
