Public functions in a QThread class: safe?

[dmginc]

The question I am about to ask was actually asked in this thread: http://www.qtforum.org/article/32113...questions.html

But wasn't really properly answered...

Here is some code to explain the question:

Subclassed from QThread:

thread::run()
{
  while(1)
  {
     if(someCondition)
       privateMember++;
  }
}

thread::run()
{
  while(1)
  {
     if(someCondition)
       privateMember++;
  }
}

To copy to clipboard, switch view to plain text mode 

thread::getPrivateMember()
{
  return privateMember;
}

thread::getPrivateMember()
{
  return privateMember;
}

To copy to clipboard, switch view to plain text mode 

Q: Is it necessary to protect privateMember with mutexes in the above case [as in a lock()/unlock() pair in run() and a QMutexLocker in getPrivateMember()] ?

OR, is privateMember automatically protected seeing as the "get" function is a member function of a QThread-derived class. In other words, run() and getPrivateMember() will never run at the same time and are thus protected?

Can someone shed some light on this?

Cheers
