\section{\class{wxSpinButton}}\label{wxspinbutton}

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 \helpref{wxSpinCtrl}{wxspinctrl} instead
as wxSpinButton is not implemented for all platforms (Win32 and GTK only
currently).

{\bf NB:} the range supported by this control (and wxSpinCtrl) depends on the
platform but is at least {\tt SHRT\_MIN} to {\tt SHRT\_MAX}.

\wxheading{Window styles}

\twocolwidtha{5cm}
\begin{twocollist}\itemsep=0pt
\twocolitem{\windowstyle{wxSP\_HORIZONTAL}}{Specifies a horizontal spin button (note that this style is not supported in wxGTK).}
\twocolitem{\windowstyle{wxSP\_VERTICAL}}{Specifies a vertical spin button.}
\twocolitem{\windowstyle{wxSP\_ARROW\_KEYS}}{The user can use arrow keys.}
\twocolitem{\windowstyle{wxSP\_WRAP}}{The value wraps at the minimum and maximum.}
\end{twocollist}

\wxheading{Event handling}

To process input from a spin button, use one of these event handler macros to
direct input to member functions that take a 
\helpref{wxSpinEvent}{wxspinevent} argument:

\twocolwidtha{7cm}
\begin{twocollist}
\twocolitem{{\bf EVT\_SPIN(id, func)}}{Generated whenever an arros is pressed.}
\twocolitem{{\bf EVT\_SPIN\_UP(id, func)}}{Generated when left/up arrow is pressed.}
\twocolitem{{\bf EVT\_SPIN\_DOWN(id, func)}}{Generated when right/down arrow is pressed.}
\end{twocollist}%
