[Interest] Is this snippet correct- concurrent run

[Sujan Dasmahapatra]

Please check this snippet if this is correct


   1. QFuture<void> Th;
   2. std::vector<QFuture<void> > Threads;
   3. int z=0;
   4. while(z<nZ) {
   5. while(QThreadPool::globalInstance()->activeThreadCount() < QThreadPool
   ::globalInstance()->maxThreadCount()) {
   6. Th = QtConcurrent::run(this,&UNRSTParser::ProcessZLayer,z);
   7. Threads.push_back(Th);
   8. z++;
   9. if(z==nZ)
   10. break;
   11. }
   12. }
   13. //cout << " ZFinished...\n";
   14. for(int th=0; th<Threads.size(); th++)
   15. Threads[th].waitForFinished();
   16. Threads.clear();
