Accesing multiple sub folders with QDir

Question

Could not find my solution in prior posts. How can I read all the files from out of my resource folder which has multiple subfolders. For example the file structure:

fonts/test1
  ...test1.ttf
fonts/test2
  ...test2.otf
fonts/test3
  ...test3.woff2
  ...test3.woff

This is what I currently have, I'm just not entirely sure how to modify to what I want.

QStringList fontFileList = QDir(":/fonts/fonts/").entryList(QStringList() , QDir::Files | QDir::NoDotDot | QDir::NoDot);
qDebug() << fontFileList;
