title: Modify the size and the type of the font
body: <p>I'm a beginner in Pyqt and I made the main form but I don't know how to modify the size and the type of the font in the Qlabel? </p>
  
  <pre><code>def __init__(self):
      QtGui.QMainWindow.__init__(self)
      self.center()
      self.setWindowTitle('GBLtda Database')
      self.setStyleSheet("background-color: white")
      self.resize(1028, 720)
      label = QtGui.QLabel('GB DATABASE', self)
      label.move(15, 10)
      self.setWindowIcon(QtGui.QIcon('db.png'))  
  </code></pre>
