    @class wxSpinCtrl

    wxSpinCtrl combines wxTextCtrl and wxSpinButton in one control.

    @beginStyleTable
    @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.
    @style{wxTE_PROCESS_ENTER}
        Indicates that the control should generate @c wxEVT_TEXT_ENTER
        events. Using this style will prevent the user from using the Enter key
        for dialog navigation (e.g. activating the default button in the
        dialog) under MSW.
    @style{wxALIGN_LEFT}
        Same as wxTE_LEFT for wxTextCtrl: the text is left aligned.
    @style{wxALIGN_CENTRE_HORIZONTAL}
        Same as wxTE_CENTRE for wxTextCtrl: the text is centered.
    @style{wxALIGN_RIGHT}
        Same as wxTE_RIGHT for wxTextCtrl: the text is right aligned (this is
        the default).
    @endStyleTable


    @beginEventEmissionTable{wxSpinEvent}
    @event{EVT_SPINCTRL(id, func)}
        Process a wxEVT_SPINCTRL event, which is generated
        whenever the numeric value of the spin control is updated.
    @endEventTable

    You may also use the wxSpinButton event macros, however the corresponding events
    will not be generated under all platforms. Finally, if the user modifies the
    text in the edit part of the spin control directly, the EVT_TEXT is generated,
    like for the wxTextCtrl. When the use enters text into the text area, the text
    is not validated until the control loses focus (e.g. by using the TAB key).
    The value is then adjusted to the range and a wxSpinEvent sent then if the value
    is different from the last value sent.
