    It is creating a template for a class derived from QObject, not a template class. You are mixing different stuff.

          "Template" in this context is simply an English word in the same way as you may have a "Template for a presentation", i.e. something generic to help you get started, from which you can then customize what you want.

              I do not agree with your opinion : What are you trying to achieve?
              My missed point is - Qt documentation call the result of their process of building a class a " template". It is NOT template TYPE by definition, it is Qt miss use of a term.
              I have no illusion that pointing that out will "achieve " anything. Qt is pushing its own terminology and continue to do so irregardless of me , a user , opinion. They are the experts , in their opinions / view.
              My only "achievement' could be to make others users of Qt aware. That is about all I could hope for.

              It is NOT template TYPE by definition, it is Qt miss use of a term.

              That's simply wrong, @AnneRanch.
              The misunderstanding is entirely on your side.

              As @Asperamanca indicated, the term "template" is standard English vocabulary. If you reserve it exclusively for what is a template in C++, you limit your own vocabulary.

              The documentation page you referred, is truly outdated, but it doesn't contain anything wrong. It uses word "template" in two different contexts:

              • TEMPLATE directive of qmake
              • creating a class definition, following a template (as @Asperamanca already explained)

              The page does not contain any mention of the term "template" in C++ code. That makes the context pretty obvious for any C++ programmer, beginners included.

                I agree that the conflict of terms here is a bit unfortunate. Then again, I cannot come up with a more fitting term for "template" in this context. If you have a better idea, you can also write documentation suggestion to bugreports.qt.io

                  I can think of another term (don't know if better or not), but I'm not allowed to comment :)))
                  The first part is a color, the second part of the word is what a certain I/O device does :)))

                          Actually I was referring to commonly used term "reddisplay".
                          ... but I agreed to @Redman so he wouldn't feel bad :)))

                                        More than enough people say it like this...
                                        I mean, there is no right or wrong.
                                        But I also don't like it as "cute".

                                        Interesting. I don't like it either and prefer "Q-T", but I make myself say "Cute" against my preference.

                                          The issue brought up here is far from the most objectionable thing on that page. I mean, have you seen THIS nonsense?

                                          Qt (pronounced as "cute", not "cu-tee")

                                          Not just no, but HELL no!

                                          You are only figuring that out now? Right from the get go (some 20 years ago) I already heard that the "official" pronunciation is "cute". Haven't adapted it yet... (I also don't say "cu-tee" because I'm German and it sounds more like "koo-teh".)

                                          Others have already played off this: There is a web toolkit for C++ heavily borrowing from Qt. It is called Wt (pronounced "witty").
