[help] About the head error: expected class-name before '{' token

[lfjking]

Look follow code:

The Main.h

Code

#ifndef MAIN_H
#define MAIN_H

#include "Thread.h"

class Thread;
class Main
{
	public:
		/** Default constructor */
		Main(wxApp* parent);
		/** Default destructor */
		virtual ~Main();
	private:
               Thread*  mthread;
};

#endif // MAIN_H

--------------------------------------------------------------------------------------------
The thread.h

Code

#ifndef THREAD_H
#define THREAD_H

#include "Main.h"

class Main;
class Thread
{
	public:
		/** Default constructor */
		Thread(Main* parent);
		/** Default destructor */
		virtual ~Main();
	private:
               Main* mMain;
};

#endif // THREAD_H

===================================the error in the  follow===============================
the threadchild.h

Code

#ifndef THREADCHILD_H
#define THREADCHILD_H

#include "Thread.h"

class Threadchild: public Thread 
{//---------------------------------------------------error: expected class-name before '{' token----------------------------------------------
	public:
		/** Default constructor */
		Thread(Main* parent);
		/** Default destructor */
		virtual ~Main();
	private:
               Main* mMain;
};

#endif // THREADCHILD_H

How to solve this problem？？？

I see no real question in your post; I suggest asking one if it does NOT violate the rules!

the Question is：
When the AB class is a class of mutual include(like as class Main and Thread)
the third class C if include one of AB class, it will error: expected class-name before '{' token,on the third class head， like as the eg. class: threadchild

This shows, that you did not (re-)read the rules.

General programming questions arenot allowed on this site/forum.
Just Code::Blocks (an IDE) related questions.

Topic locked, because it violates our forum rules. Sorry.
