PyQt5 QSpinBox – Setting weight to the text

In this article we will see how we can set the weight to the spin box’s text. Font-weight is meant for setting the weight (boldness) of the font. The more the value of weight the more text will be bold.

In order to do this we use setWeight method with the QFont object of the spin box.

Syntax : font.setWeight(n)

Argument : It takes integer 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")

        # getting font of the spin box
        font = self.spin.font()

        # setting weight to the font
        font.setWeight(75)

        # reassigning this font to the spin box
        self.spin.setFont(font)



# create pyqt5 app
App = QApplication(sys.argv)

# create the instance of our Window
window = Window()

# start the app
sys.exit(App.exec())

Output :
