Hi,
I'm trying to get templated states to work with boost::fsm. Background
is that I want to create an OptionsDialog I can show from different screens.
So for now this works:
template<class ParentState>
class OptionsDialog : public boost::fsm::simple_state<
OptionsDialog<ParentState>, ParentState,
boost::mpl::list<
boost::fsm::transition,
boost::fsm::custom_reaction<EvOptionsSound>,
boost::fsm::custom_reaction<EvOptionsSoundExit>
> >
{
//...
};
This works perfectly so far.
Now, what I want to do is have inside of the OptionsDialog substates
(one for the sound-panel, one for video, etc.).
This is my attempt so far:
template <class Parent> class InnerInitial;
template<class ParentState>
class OptionsDialog : public boost::fsm::simple_state<
OptionsDialog<ParentState>, ParentState,
boost::mpl::list<
boost::fsm::transition,
boost::fsm::custom_reaction<EvOptionsSound>,
boost::fsm::custom_reaction<EvOptionsSoundExit>
> >,
InnerInitial< OptionsDialog<ParentState>
{
//...
};
template <class Parent> class InnerInitial : public
fsm::simple_state
{
};
When trying to compile this (and of course using the OptionsDialog as a
substate somewhere) I get the following compiler errors (sorry, I know
it's long, but I couldn't make any sense of it so I don't know whats
important). Could anyone shed some light on this?
Thanks a lot,
Jan Eickmann
