Can I determine if a thread has a QEventLoop?

Question

I am writing a Windows DLL that can run under QApplication or can run under a regular Win32 application. I want to use Qt Networking classes that require an event loop.

If you are working in a regular Win32 application (not Qt), I have to run QThread or QEventLoop for network signals and Qt slots for operation. Note. DLL uses QtWinMigrate. But if you work in QApplication, then there will already be a cycle of events, and there is no need to start a new QThread.

Is there a way to check an existing QEventLoop?

Explanation of the DLL works under a large old code base, and the thread in which my class runs may or may not be QThread.
