How can one reorder items in an hbox?
Specifically, if there was a panelA and panelB added (both with flex of 1) (so A is left B is right)
How could one switch the order of those two around? (so panelB is left and A is right)
I can change the container.items (.items) order, but I don't see how to reapply the layout.
Is the only way to store the items, destroy the container, and create a new container with those items applied in a different order?
