PyQt5 QSpinBox – Accessing Family Name

Report issue

In this article we will see how we can get the family name of the font of spin box. The family name may optionally also include a foundry name, e.g. “Helvetica [Cronyx]”. If the family is available from more than one foundry and the foundry isn’t specified, an arbitrary foundry is chosen. If the family isn’t available a family will be set using the font matching algorithm. In order to set family name we use setFamily method. In order to get the information about the font we have to get the QFontInfo object of spin box which can be done using fontInfo method.

In order to do this we use family method with the QFontInfo object of the spin box Syntax : Argument : It takes no argument Return : It returns string

Below is the implementation 


# importing libraries
from PyQt5.QtWidgets import *
from PyQt5 import QtCore, QtGui
from PyQt5.QtGui import *
from PyQt5.QtCore import *
import sys
class Window(QMainWindow):
    def __init__(self):
        # setting title
        self.setWindowTitle("Python ")
        # setting geometry
        self.setGeometry(100, 100, 600, 400)
        # calling method
        # showing all the widgets
        # method for widgets
    def UiComponents(self):
        # creating spin box
        self.spin = QSpinBox(self)
        # setting geometry to spin box
        self.spin.setGeometry(100, 100, 250, 40)
        # setting range to the spin box
        self.spin.setRange(0, 999999)
        # setting prefix to spin
        self.spin.setPrefix("PREFIX ")
        # setting suffix to spin
        self.spin.setSuffix(" SUFFIX")
        # creating a label
        label = QLabel(self)
        # setting geometry to the label
        label.setGeometry(100, 200, 300, 60)
        # getting the font info
        font_info = self.spin.fontInfo()
        # getting family name
        name =
        # setting text to the label
        label.setText("Family Name : " + name)
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
