\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 arrow 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}%

Note that if you handle both SPIN and UP or DOWN events, you will be notified
about each of them twice: first the UP/DOWN event will be received and then,
if it wasn't vetoed, the SPIN event will be sent.
