How to hide mac dock icon for QApplication?

[Sandrock]

Hi,
I have a console app that initializes QApplication that needs the QPainter to work. When run it, there is a icon shows in the mac dock bar. Does anyone know how to get rid of it? I just want the console app to be run in background.

I tried to use QCoreApplication, it has no icon there, but QPainter will not work without QApplication.

Best Regards
