I have various bits of functionality that I need to attach to Squirrel as C++ classes.

Doing this with SQRat is simple enough... however...

To operate they require certain context information, which is known at the time of binding.

So the constructor might look something like


class ParameterListener {

ParameterListener { ParameterTree* parameter_tree,
                    Sqrat::Object sq_callback_object,
                sq_string sq_callback_function,
                sq_string search_string );


Where the value of parameter_tree is known at bind time.

Now, I assume I could set the value in a slot in Squirrel, and then construct a ParameterListener Object in squirrel with


parameter_listener = ParameterListener(the_parameter_tree, this, OnParameterChange, "");

But the thing is, since in this case there will only ever be one parameter tree for a single Squirrel VM, and it won't change in location during the lifetime of the VM, I would rather that the script writer didn't have to think about it, and could just write


parameter_listener = ParameterListener(this, OnParameterChange, "");

So, is there a way to bind cnostructors (and other functions ideally) such that onky some parameters are exposed to Squirrel, and the others are filled with values given at bind time?
