[wxlua-users] Deriving from wxDataObjectSimple

[strawman <str...@la...>]

 From the wx docs for wxDataObjectSimple:

"Notice that this is still an abstract base class and cannot be used but 
should be derived from.
The objects supporting rendering the data must override GetDataSize and 
GetDataHere while the objects which may be set must override SetData."

Is it possible to use this class from Lua?  I'm trying to register a 
custom clipboard format and can't see any other way of passing a custom 
wxDataFormat.
