Your loop does have one problem there...you're going to skip more or
less every other view while doing this. Also, you need to be calling
RemoveChild off fParent, not off your current view, it can't remove
what isn't attached to it.

Try:

while (fParent->CountChildren() > 0) {
fParent->RemoveChild(fParent->ChildAt(0));
printf("%d\n", fParent->CountChildren());
}
