C++ friend classes, with structs and enums

[kachofool]

Hey all,

I ran into a bit of an issue using Qt with nested C++ classes. Namely, moc doesn't support nested classes, and I need to restructure some of my code to reflect this.

Since friend classes and nested classes are pretty similar I wanted to convert my nested classes into friend classes. The problem is that my "outer" nested classes often have enums or structs that are accessible to the "inner" nested classes. I don't quite get how to access these typedefs using friend classes without making them global.

ex:

class Temp
{
   friend class FriendOfTemp;
   public:
   struct infoRow
   {
      int blah;
      int blah2;
   };
 
   enum osTypes
   { win, osx, linux, unix, beos, qnx};
};
 
class FriendOfTemp
{ ... };
 
FriendOfTemp::FriendOfTemp
{
   os_type = linux   // wouldn't make sense
   infoRow newRow;   // wouldn't work
}

class Temp
{
   friend class FriendOfTemp;
   public:
   struct infoRow
   {
      int blah;
      int blah2;
   };

   enum osTypes
   { win, osx, linux, unix, beos, qnx};
};

class FriendOfTemp
{ ... };

FriendOfTemp::FriendOfTemp
{
   os_type = linux   // wouldn't make sense
   infoRow newRow;   // wouldn't work
}

How would I go about doing this?
