Class communication methods

I've been planning some things for the game I'm currently working on, here's an excerpt from my 'plan list' that I could use some guidance with:

Code:

---

        3. A map class (CMapControl?) to handle creation and rendering of maps.
          Having the map class load the map scripts itself would be ideal in that
          it's easier to manage, but I want to have seperate classes "doing their
          own thing", therefore a script parsing class should load and parse the map
          script, sending necessary data to the map class for rendering etc.
         
        4. A script class. Should handle reading and parsing of script files with
          some sort of global method of transferring arbitary data between other
          interfaces, e.g. parsing a map script (tile layout etc) and sending the
          tile data to the map class for rendering etc

---

I can't think of a method that would allow me to accomplish this without having the map class load and parse the files itself.

idea 1:
class CMapControl : public CMapScriptParser

This allows the code to be handled in another object, making it easy to manage, but still has the CMapControl doing all the work

idea 2:

class CMapControl
class CMapScriptParser
class CMapDataHandler

a CMapScriptParser reads all the data, and shoves it into a CMapDataHandler, which is what the CMapControl object references when it needs data.

Idea 3:
class CMapDataHandler
class CMapControl : private CMapDataHandler
class CMapScriptParser private CMapDataHandler

A bit of both the last 2 ideas. The best way to go about this idea would be to have CMapDataHandler set up as a singleton.

Ok thanks for the ideas. Haven't seen you around here for a while skorman, where you been?
