Is Qt for GUI only?

It is not only for programming a GUI. QtCore, QtXml, QtSql etc. all doesn't belong to GUI. So Qt is also quite perfect to code an engine. Just go ahead an you'll see.

Aha..but can I also add code(for the engine)in my main.cpp file?
And can you please recommend a good tutorial/book that expalines Qt well?

Thanks.

I am sorry, but I don't get you. What do you want to do?

There are a lot of thread about that at the forum. But also my favorite one of Johan Thelin is mainly focused on GUI creation. So better say what kind of library you are planing and we probably point you to the important classes you will need to know. Also the documentation is good enough to learn.

Well,when you are coding in a console app. you have the main function,where everything happens,I asked if the file main.cpp hold ass well the code for the engine(like commends besides the GUI..:/)

And I don't have in mind anything specific right now,I just want to learn using Qt as a normal language....so that I can create any project I like.

Qt is not a language. Qt apps are usually written in C++ so everything that applies to any C++ application applies to Qt applications too.

Ok,so as I understand I can code(functionality) in Qt...so any good books to get me started?

Have you completed the address book tutorial ?

The documentation is also very good if you don't understand something.

If you can't find something in the documentation (or don't understand it) then you are welcome to post here.

There is also a thread on this forum about books, should you prefer to learn that way.

Thank you...
How much does it usually take to learn Qt and create applications alone?

Time to learn or time to write?
Anyway, that's very subjective. It depends from person to person. Some people learn fast or write fast, others require more time and practice.

What do you already know about computer programming? Do you know any languages? Techniques? ...

Yes,I have been learning C++ for 2 months(approximately) now,and I have learned everything basic to some advanced stuff(loops,ifs,typedef,structures,classes,inherit ance,polymorphism,pointers,functions....).

To make you understand better I have completed this,I was reading MSDN'S C++ Beginner Guide parallel with C++ in 21 days,and also read the tutorial at http://www.learncpp.com/

I have made small projects like TicTacToe game(OOP),a letter counter(from a file,with ifstream....)

Well,nearly all these...would it be difficult for me to get used to Qt?
BTW:I downloaded today C++ GUI Programming with Qt 4 (2nd Edition).
