Communication/data sharing between threads

[Tottish]

Yeah, I've read that but I was lead to believe that this was only necessary when the variables in question had multiple threads that wanted to write to them. Only one of my threads write to a variable and the other threads are strictly readers.
Isn't that true?

EDIT: Tested with mutex. No difference.

Show us some code : declaration of this variables and code accessing them. The glass ball is not working today

If you have a thread that writes and a thread that reads, you need locking unless the variables are simple types such as 'char'.

Have a look at QReadLocker & QWriteLocker. The former locks for read access, the later locks for write access.

dear Lesiok,
I have some how such a problem with data sharing with different threads.
but the difference is that when I wanna read a static array in different array they know it by different address :-??
