PyQt5 QSpinBox – Setting font to the whole text
  • Last Updated : 19 May, 2020

In this article we will see how we can change the size and font of all the text present in the spin box, in order to do so we will use setFont method which takes QFont object as argument, using it with the spin box object will change the font of all the text.

Syntax : spin_box.setFont(font)

Argument : It takes QFont object as argument

Return : It returns None

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):
        super().__init__()
  
        # setting title
        self.setWindowTitle("Python ")
  
        # setting geometry
        self.setGeometry(100, 100, 600, 400)
  
        # calling method
        self.UiComponents()
  
        # showing all the widgets
        self.show()
  
        # 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")
  
        # font
        font = QFont('Arial', 12)
  
        # setting font to the spin box
        self.spin.setFont(QFont(font))
  
  
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
