Oy!

Recursion would be _ **SO** _ much easier to read.

Start with something like this:

```auto
#------------
# Recursively scan a container for children and the children's children, calling
# a given routine for each child encountered.
#
def forEachChild(container, func, lvl=None):
	if not lvl:
		lvl = 1
	func(container, lvl)
	for i in range(container.getComponentCount()):
		component = container.getComponent(i)
		forEachChild(component, func, lvl+1)

```

Pass it a function that takes a component and the depth as its parameters.

{ Note that this version enumerates the nested objects of regular components, too. }
