    @class wxWrapSizer

    A wrap sizer lays out its items in a single line, like a box sizer -- as long
    as there is space available in that direction. Once all available space in
    the primary direction has been used, a new line is added and items are added
    there.

    So a wrap sizer has a primary orientation for adding items, and adds lines
    as needed in the secondary direction.
