/**
    @class wxSpinButton
    @wxheader{spinbutt.h}

    A wxSpinButton has two small up and down (or left and right) arrow buttons. It
    is often used next to a text control for increment and decrementing a value.
    Portable programs should try to use wxSpinCtrl instead
    as wxSpinButton is not implemented for all platforms but wxSpinCtrl is as it
    degenerates to a simple wxTextCtrl on such platforms.

    @b NB: the range supported by this control (and wxSpinCtrl) depends on the
    platform but is at least @c -0x8000 to @c 0x7fff. Under GTK and
    Win32 with sufficiently new version of @c comctrl32.dll (at least 4.71 is
    required, 5.80 is recommended) the full 32 bit range is supported.

    @beginStyleTable
    @style{wxSP_HORIZONTAL}:
           Specifies a horizontal spin button (note that this style is not
           supported in wxGTK).
    @style{wxSP_VERTICAL}:
           Specifies a vertical spin button.
    @style{wxSP_ARROW_KEYS}:
           The user can use arrow keys to change the value.
    @style{wxSP_WRAP}:
           The value wraps at the minimum and maximum.
