Threading in Qt - Confusion

[StarShaper]

Hi,

I'm new to Qt and I am pretty confused by the way threading is done with Qt. If I look into the official docs, there is always the same way to create a thread. Create a subclass of QThread and implement your own run() function.

Even new books about Qt 4 are telling this. It is pretty much the same, like in Java.

Now I found this site.

and this

They are telling that subclassing QThread is wrong. Why do the official docs still listing the old "wrong" way?

To create your own threads, subclass QThread and reimplement run().

And is it really wrong to subclass QThread? Do I have to use moveToThread()?

I would tell you but I don't like using bad words in public.

No, it's not inherently wrong but most of the time moveToThread() is better.
