Creating a GUI-system is actually a great practice for learning both C++ as well as a simple library like SFML. Create "widgets" in classes like TextInput boxes, Labels, Buttons etc, in a way that makes them reusable.
... When I was searching the sfml docs I din't find any textinput options... I guess I din't try hard enough.
Is your application purely GUI ?
If yes I think SFML is not the best library for you...
.QuoteCollection of data, memory management, classes, garbage collection, windowing system, polymorphism, inheritance?Not sure what you mean by first, second and third - yes, but use smart pointers for your memory managment, 99% chances are that you won't implement better memory managment no matter how hard you try, last two too. But c++ doesn't contain built in garbage collector and windowing system(??)/gui of any kind.
Read these two FAQs from Bjarne Stroustrup(original designer and crator of c++), they're great and contain important information about macros, casts and (lack of) garbage:

vaironl, I hope you're not reading "The C++ Programming Language". That's a reference book by Bjarne. "Programming: Principles and Practice Using C++" is the better choice.
Good for me I have "Programming: Principles and Practice Using C++"
The reason for this is because the book "The C++ Programming Language" is a good book if you know some C++ or at least C, if you don't then all you will do is get confused with it.QuoteAnd one should especially learn what RAII is, as it will make memory and resource management a lot simpler. Using manual memory management with new and delete is mostly bad practice.
I forgot to cite RAII, thank you for pointing it out.
As a side note, if you get into RAII then try to learn normal pointer and memory management first, not for using them in a practical way (that's pretty much the reason why RAII is awesome), but to know how they work and what RAII does underneath.

QuoteI'm transferring from Java to c++, and I know that it sounds off-topic but I do come to ask some questions SFML related as well. I actually asked this same question, in some way, in another forum and got suggested to start with SFML rather than openGL or SDL.
And you got a good suggestion, but an even better one would be to start learning only C++ first, I come from Java myself and the change is incredibly big, since you don't use destructors, pointers, references and no garbage collection means that you have to be careful with scopes of variables and what you send to heap memory.
Java is a higher level language than C++, which pretty much abstracts you from a lot of what goes on underneath and learning all that takes time. In my opinion it's too much to learn C++ while trying to learn SFML as well. Also note that SFML tutorials and most material require you to know your basic C++, so I'd suggest you take your time with a C++ book first and then once you have a handle of things you can use SFML without as many problems or doubts later.QuoteLately I've gotten interested in video games and similar graphic applications. I understand I can do it in Java, and did so. But I want to try it in c++ for fun and to see performance differences.
Performance will be better, don't doubt it, C++ is much faster than Java.QuoteAny advice that can be given on whether I should first make those "Beginner" applications.. relearn about using classes, and core topics in c++ (Which I will obviously have to do sooner or later)... or could I just jump straight into making graphic applications?
As stated above, you better avoid it and learn C++ well before going into graphic applications.

Most of the examples there are reliable, I haven't read it all so I can't tell if there's anything that's not, but it seems like a good read to get into C++ from Java. Good luck.
