How to build real template class?

Asperamanca

The important question is: What are you trying to achieve?
I struggle to see a compelling use case for a templated QObject, but I might be missing something...

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

Could you link the relevant documentation page?

"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 disagree , especially when it is " for beginners" .

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The documentation page you referred, is truly outdated, but it doesn't contain anything wrong.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 :)))

Yep. That's it :))
You're good :D

@Redman
C'mon, ever seen a yellow fax?
He meant orange jam, obviously.

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

That's what you get when using yellow fax wrong :))

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!

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".
