[lni]

Hi,

I am trying to set QApplication default font using following qss, but it doesn't work. How can I do that? Thanks

QApplication {
  font-family: Arial;
  font-size: 12px;
  font-weight: Normal;
}

QApplication {
  font-family: Arial;
  font-size: 12px;
  font-weight: Normal;
}

  font-size: 12px;
  font-weight: Normal;
}

* {
  font-family: Arial;
