\section{\class{wxActiveXEvent}}\label{wxactivexevent}

An event class for handling activex events passed from
\helpref{wxActiveXContainer}{wxactivexcontainer}. ActiveX events are basically
a function call with the parameters passed through an array of wxVariants along
with a return value that is a wxVariant itself. What type the parameters or
return value are depends on the context (i.e. what the .idl specifies).

Note that unlike the third party wxActiveX function names are not supported.
