Background threads running in Qt Application.

[vipu]

I execute the code below

#include <QApplication>
 
int main (int argc, char** argv)
{
  QApplication app(argc, argv);
  app.exec();
}

#include <QApplication>

int main (int argc, char** argv)
{
  QApplication app(argc, argv);
  app.exec();
}

To copy to clipboard, switch view to plain text mode 

and see the process on Windows Task Manager (WTM).

The WTM shows 7 threads for this application.

I read that Qt does not create any thread in the background then
why does it get reflected on WTM.
