I ran into this once before in another area, and after a brief look searching/not finding anything thought I would just ask.
I can use addChild to add nest elements to a label.
How do I delete (individual) nest elements?
For example, button X currently has 3 nested children. I need to change that to being the same button X, but with only 2 children. Is their a command to do this? If not, would there be a command to just delete all children, and re-add them individually?
