main and background thread example

[SGaist]

Did you check the memory used by you application ?

@SGaist

what do you mean by check? and no, how should i?

[SGaist]

Using the top command for example. Valgrind etc.

@SGaist

okay, thanks.
one last question, as you can see, on timer's timeout i execute a function. is it possible stop the timer (so the function won't be executed), and then restart it again?

[SGaist]

Yes:
QTimer::stop
QTimer::start

@SGaist

hi again,
i ran valgrind and it says there's a memory leak on exec() which is in run() overridden method. so what's wrong?

@user4592357 said in main and background thread example:

ThreadObj obj;
m_thread = std::thread(&ThreadObj::work, &obj);

obj is allocated on the stack, it will go out of scope and delete itself

@VRonin

hi, thanks for the reply.
the code has been modified since the first post (see my last code-post), so it's not the problem

@VRonin

i've read similar articles, saying "you shouldn't subclass QThread". in my case i need to do that.

[SGaist]

Out of curiosity, what are you doing that requires to subclass QThread ?

[user4592357]

@SGaist

nothing requires it. it's just that the whole implementation is done and i don't wanna change everything
