# setSelection(This, N)

    -spec setSelection(This, N) -> ok when This :: wxRadioBox(), N :: integer().

Sets the selection to the given item.

Notice that a radio box always has selection, so `n` must be valid here and passing `wxNOT_FOUND` is not allowed.

# show(This, Item)

    -spec show(This, Item) -> boolean() when This :: wxRadioBox(), Item :: integer().

Equivalent to `show(This, Item, [])`.

# show/3

Return: true if the item has been shown or hidden or false if nothing was done because it already was in the requested state.
