NTK Templates

Seeing the _parent Slot

As we said previously, although you see _proto slots in NTK, you do not see _parent slots. This is because templates and protos don't contain _parent slots, only views do. For those templates that have children, NTK adds a stepChildren slot, which is an array of templates. At runtime, the view system reads that slot and creates child views based on the slot. The view system then sets up the _parent slot in the view. This topic is discussed in complete detail in "How Views Are Created" on page 142. You will not see the stepChildren array in the browser either. NTK creates the array as it builds the application.
