Re: [Boost-users] [statechart] post_event() and Boost.Bind

Thanks for your helpful advice. The following line

post_event_fun_	= boost::bind( static_cast<void (Camera::*)(const 
event_base_type&)>(&Camera::post_event), boost::ref(*this ), _1 );

works perfect. I thought your way too. There are 2 overloads of 
post_event(). But I hoped that Boost.Bind could solve this in any magic way. 
And until now I was not aware about the option to cast a method. So I have a 
solution and learned something new. Thats great.
