/**
    @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.

        the values @c wxEXTEND_LAST_ON_EACH_LINE which will cause the last item
        on each line to use any remaining space on that line and @c wxREMOVE_LEADING_SPACES
        which removes any spacer elements from the beginning of a row.

        Both of these flags are on by default.
