Can I access the children of a component from the parent?

Anvil Q&A

If I nest components C1,…Cn inside of a parent component P, could I access the child components from the parent? I think the answer is no, unless I explicitly maintain a list of references in code.

A toy example:

def __init__(self):
  self.p = MyParentComponent()
  self.add_component(self.p)
  self.p.add_component(c1)
  ...
  self.p.add_component(cn)
def get_children(self):
  # I cannot get self.p's children because I did not maintain an explicit reference
  pass

From a design perspective, why do we not have a way to get the children of a component at run time, similar to how it’s possible to get HTML DOM element’s children?

const collection = document.body.children;

Every container has a method called get_components() which returns an iterable of the container’s children.
