Adding wxWidgets to existing app

[GyroTech]

Thanks for the ideas. I managed to hack something together earlier, 
creating a wxApp that opens a frame during OnInit as normal, then 
overriding OnRun() to work my OpenGL SDL window, like this:-

while( !done )
{
   if( Pending() )
     Dispatch();

   if( SDL_PollEvent( &event ) )
   {
     // Do SDL stuff here
   }

   // Draw OpenGL scene here
}

This seems to work for the most part, but I was wondering how, upon 
checking Pending() I could check the event waiting, and if it's a custom 
one for my code to run (loading objects, changing lights etc) do 
something, otherwise just pass it on to Dispatch()

Is this a decent way of doing things or have I put together a terrible 
kludge?? ;-)

Thanks
