so many things i dont understand ...

Code: [Select]

class MyPicture
{
public :

    // This is the copy constructor
    MyPicture(const MyPicture& Copy) : Image(Copy.Image), Sprite(Copy.Sprite)
    {
        // This is the trick : we setup the sprite
        // to use our image, instead of the one of Copy
        Sprite.SetImage(Image);
    }

    // ... a lot of useful functions ...

private :

    sf::Image  Image;
    sf::Sprite Sprite;
};

how can a normal instance be created? for me it seems that the creation of MyPicture requires an instance of MyPicture?

This is not a complete class, there's just the tricky part i.e. the copy constructor.

Of course you have to add your own constructors and functions.

Perhaps you first need to read some good tutorial or book about C++ ?

well i did some tutorials and i have read some books (4 of them are mine)
but somehow i believe their niveau is just to low xD

as u surely have seen some of my questions are just about c++
and not bout sfml what they should be
but nevertheless i hope i can stillask u if i have problems

( to outpoint it, for example i never heard of stringstreams before, and in none of my books they are mentioned, only fstreams in a two pages chapter, but i needed them and ure help and the easy usage of sfml (( i tried to do some projects using DX 9 - so i know that sfml is VERY easy - good job)) have helped me to find the motivation and possibility to do my first acceptable results)
if u have a good book for me ( it shouldnt begin with "what is c++" but it shouldnt start with networkprogramming) i am open for every good advice

My preferred book for learning C++ is Walter Savitch's "Problem Solving in C++: The object of programming"

I got it as a textbook for a class and have since made my way through the whole book in my spare time. It starts with the very basics and makes its way into advanced object-oriented concepts. Pretty much everything I know about C++ I've learned from this book.

Whether you need help with using strings, creating linked lists or working with virtual functions, this book covers it. It is quite simply an excellent book. I keep it around and reference it often whenever I need to.
