Hello,

I have make a class derived from QString class and i want to overload typecast myString to char* conversion. i did as following.

// mystring.h
#ifndef MYSTRING_H
#define MYSTRING_H

#include <QString>

class MyString : public QString
{
public:
    MyString();
    operator char*()
    {
        QByteArray ba = toLocal8Bit();
        return ba.data();
    }
    void operator =(const QString& str){ clear();append(str);}
};

#endif // MYSTRING_H


// main.cpp file

#include <mystring.h>
int main(int argv,char* argc[])
{
   char* strChar = NULL;
   MyString strMy;
   strMy = "Hello";
   strChar = strMy;
   int i = 0;
}

but i can't get "Hello" in strChar.
How do i overload operator char* ?
I can't get whats wrong in my code.


Thanks in advance.
