    QFile style_file(file_path);
    if(style_file.open(QIODevice::ReadOnly))
    {
      qDebug() << "Readin file OK!";
      w.setStyleSheet(style_file.readAll());

You're supposed to put the content of a stylesheet in QWidget::setStyleSheet, not a path to a file. So open your file with QFile, read the contents and set that as your stylesheet.

Here is an example:

QFile style_file("path/to/stylesheet/darkorange.stylesheet");
if(style_file.open(QIODevice::ReadOnly))
    this->setStyleSheet(style_file.readAll());

Try passing the absolute path to the stylesheet file:

QCoreApplication::applicationDirPath() + QString("darkorange.stylesheet");
