Inherit problem in the class

[mena_mes]

Hi everyone,

I am new in Qt world :)

I created 2 class one inherit from the other one. Please find below my code :

#include "cclass2.h"


class CClass1
{
public:
    explicit CClass1(CClass2& p_class);
    ~CClass1();
public: // Data
 
protected:
    CClass2& p_class2;

};

but I get the error : expected ')' before '&' token explicit CClass1(CClass2& snapshot);

any help please

This has nothing to do with Qt. It's just plain C++

Where exactly do you get this error? In your class header or when create an instance of it?

The code snippet mentioned in the error message does not exist in the code you posted. Start by looking for the code that matches the error message; possibly in the C++ source providing the implemenation.

@mena_mes In the code you posted I don't see any inheritance.
Does CClass2 inherit from CClass1?
Does cclass2.h include cclass1.h? If so you have circular dependency. Change

CClass2& p_class2;

to

CClass2 *p_class2;

Remove

#include "cclass2.h"

and add

class CClass2; // Forward declaration

before CClass1 declaration.
And as already pointed out: this has nothing to do with Qt.
