Creating QObjects before QCoreApplication

Is this correct to create and use QObjects before I create an instance of QCoreApplication? I'm writing an application, which works as system service and I need to do initialization (Write log using QFile for example) before I create QCoreApplication

hi dawwin,

I know that only QApplication has such a requirement that it needs to be created before any other UI object.
There is nothing like this in the docs about QCoreApplication.

The application object is the one responsible for the event loop.
You can create QObject before the QApplication / QCoreApplication but you wont be able to use events or signal slots.
But writing / reading from a file should not be a problem.
