PyQt5 QSpinBox – Setting Hinting Preference

In this article we will see how we can check if the text of the spin box is fixed pitch or not, a mono-spaced font, also called a fixed-pitch, fixed-width, or non-proportional font, is a font whose letters and characters each occupy the same amount of horizontal space. This contrasts with variable-width fonts, where the letters and spacings have different widths. 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 fixedPitch method with the QFontInfo object of the spin box Syntax : font_info.fixedPitch() Argument : It takes no argument Return : It returns bool

Below is the implementation 

Python3

# importing libraries
from PyQt5.QtWidgets import *
from PyQt5 import QtCore, QtGui

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")


        # 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 fixed pitch status of text
        check = font_info.fixedPitch()

        # setting text to the label
        label.setText("Fixed Pitch ? : " + str(check))


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

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

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

Output :
