\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{wxScrollEvent}{wxscrollevent} argument:

\twocolwidtha{7cm}
\begin{twocollist}
\twocolitem{{\bf EVT\_SPIN(id, func)}}{Catch all scroll commands.}
\twocolitem{{\bf EVT\_SPIN\_UP(id, func)}}{Catch up (or left) commands.}
\twocolitem{{\bf EVT\_SPIN\_DOWN(id, func)}}{Catch down (or right) commands.}
\twocolitem{{\bf EVT\_COMMAND\_TOP(id, func)}}{Catch a command to put the scroll thumb at the maximum position.}
\twocolitem{{\bf EVT\_COMMAND\_SCROLL(id, func)}}{Catch all scroll commands.}
\twocolitem{{\bf EVT\_COMMAND\_TOP(id, func)}}{Catch a command to put the scroll thumb at the maximum position.}
\twocolitem{{\bf EVT\_COMMAND\_BOTTOM(id, func)}}{Catch a command to put the scroll thumb at the maximum position.}
\twocolitem{{\bf EVT\_COMMAND\_LINEUP(id, func)}}{Catch a line up command.}
\twocolitem{{\bf EVT\_COMMAND\_LINEDOWN(id, func)}}{Catch a line down command.}
\twocolitem{{\bf EVT\_COMMAND\_PAGEUP(id, func)}}{Catch a page up command.}
\twocolitem{{\bf EVT\_COMMAND\_PAGEDOWN(id, func)}}{Catch a page down command.}
\twocolitem{{\bf EVT\_COMMAND\_THUMBTRACK(id, func)}}{Catch a thumbtrack command (continuous movement of the scroll thumb).}
