Design Pattern to update child objects when parent changes

[Tayrnis]

I think I found a decent solution with this simple function:

bool getParentVisible(void)
{
	if (m_parent)
	{
		return m_parent->getParentVisible() && m_visible;
	}
	else return m_visible;
}

This traverses each parent in a chain up to the topmost parent comparing the visibility with the current object. This is the first time I've ever found a use for recursion!
