get status of QRunnable

[Qtonimo]

Hi I have a question ; )...

I want to use QThreadPool to run several QRunnble Tasks concurrent.

f.e. There is a machine with 8 cpu's.
I want to start 8 Runnbles. But after 5 seconds my mainthread want to know the status of each runnable.

t1: 10% finished
t2: 70% finished
and so on....

What is the easiest approach to query a member of a QRunnable, while executing?


thanks in advance

How exactly would the runnable know if it is at 10% or 90% of its work?

[Qtonimo]

Thank you for your reply...

Because there is a loop in the run method and I know the count.

[wysota]

Then emit a signal and catch it somewhere or store the status in some member variable (possibly of type QAtomicInt) of the runnable object and read it from there.

[Qtonimo]

But storing the status in a member of normal type int is not possible? Is this right?

So I have to use QAtomicInt....

You can store it however you like.

Ok, this works very well. So a getter method is possible between different threads.

But why you recommended QAtomicInt?
