+ An event class for handling ActiveX events passed from 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.

@endEventTable
+ ActiveX event parameters can get extremely complex and may be beyond the
+ abilities of wxVariant. If 'operator[]' fails, prints an error messages or
+ crashes the application, event handlers should use GetNativeParameters()
+ instead to obtain the original event information.
+ Calls to operator[] and GetNativeParmeters() can be mixed. It is valid
+ to handle some parameters of an event with operator[] and others directly
+ through GetNativeParameters(). It is \b not valid however to manipulate
+ the same parameter using both approaches at the same time.
