PyQt5 QSpinBox – Getting vertical physical DPI

In this article we will see how we can get the vertical physical DPI of the spin box. DPI refers to the physical dot density of an image when it is reproduced as a real physical entity, for example printed onto paper. A digitally stored image has no inherent physical dimensions, measured in inches or centimeters. Vertical DPI is across y-axis.

In order to do this we use physicalDpiY method with the spin box object.

Syntax : spin_box.physicalDpiY()

Argument : It takes no argument

Return : It returns integer

Below is the implementation

# importing libraries

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(1, 999999)

        # setting prefix to spin
        self.spin.setPrefix("PREFIX ")

        # setting suffix to spin
        self.spin.setSuffix(" SUFFIX")

        # creating a label
        label = QLabel(self)

        # making the label multi line
        label.setWordWrap(True)

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

        # getting vertical Physical DPI
        value = self.spin.physicalDpiY()

        # setting text to the label
        label.setText("Vertical Physical DPI : " + str(value))


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

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

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