QDataStream serialze & deserialize 'myclass' pointer

How to handle QDataStream to my classes, this are stored in one 'header' file.
It's uncomfortable for me because I have many issues.
I learnt to my classes QDataStream >> and << operators.For Example:
#ifndef POINT3D_H #define POINT3D_H #include "QObject" #include "QDataStream" class Point3D { public: Point3D(); int x; int y; int z; Point3D(int _x, int _y, int _z) { this->x = _x; this->y = _y; this->z = _z; } friend QDataStream & operator << (QDataStream &stream, const Point3D &obj); friend QDataStream & operator >> (QDataStream &stream, Point3D &obj); }; Q_DECLARE_TYPEINFO(Point3D, Q_MOVABLE_TYPE); #endif // POINT3D_H#include "point3d.h" Point3D::Point3D() { } QDataStream & operator << (QDataStream &stream, const Point3D &obj) { stream << static_cast<qint32>(obj.x) << static_cast<qint32>(obj.y) << static_cast<qint32>(obj.z); return stream; } QDataStream & operator >> (QDataStream &stream, Point3D &obj) { qint32 tempint; stream >> tempint; obj.x = static_cast<int>(tempint); stream >> tempint; obj.y = static_cast<int>(tempint); stream >> tempint; obj.z = static_cast<int>(tempint); return stream; }I want to be sure that this will work from anywhere. Can you confirm it?

I don't understand the question, could you elaborate.

I have class Point3D which know how to behave when datastream requires input(<<) or output(>>) operators.
I want to know if it will works from anyclasses, for example: from mainwindows and etc..Do what you want.
