PyQt5 QSpinBox - Checking if Kerning is enabled or not

Last Updated : 22 May, 2020

In this article we will see how we can check if the kerning of spin box text is enabled or disabled. In typography, kerning is the process of adjusting the spacing between characters in a proportional font, usually to achieve a visually pleasing result. Kerning adjusts the space between individual letter forms, while tracking adjusts spacing uniformly over a range of characters. By default this property is True although we can change this using setKerning method with the QFont object of the spin box. In order to do this we use kerning method with the QFont object of the spin box

Syntax : font.kerning() Argument : It takes no argument Return : It returns bool

Below is the implementation

Python3 1==

# importing libraries

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()

        # disabling the kerning effect
        font.setKerning(False)

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

        # creating a label
        label = QLabel(self)

        # setting geometry to the label
        label.setGeometry(100, 200, 300, 60)

        # getting kerning status
        check = font.kerning()

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


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

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

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