I was thinking of using Boost.Statechart as a state machine to manage widget states in my wxWidgets application. Depending on what menu options the user picks in my program, certain buttons on the main window will be enabled or disabled. I figured this would be a good opportunity to use Boost's state machine system. I would create states that would enable or disable certain buttons depending on what events I publish. For example, when the user chooses the "Edit Name" menu item, then buttons for editing a name would be enabled. This means I'd publish a EditNameEnabled event, or something, and then the EditNameMode state would become active, and its constructor would enable certain buttons.

Of course, this means I'll need to be able to pass construction parameters to certain fsm state objects, and in the Statechart tutorial they only use default constructors. I'm not sure how I'd pass button object pointers to these state classes so they can work with them. I have two questions:

First, does Boost.Statechart seem like the right tool for this job? If yes, then how can I pass parameters to state object constructors? Would I pass the parameters to the Event's constructor, and then somehow access that event instance from the state's constructor?
