In this article we will see how we can get the pixel size of the text in spin box. Pixel size change the size of each pixel of the text there more the value of pixel the more text will get enlarged. We can change the pixel size with the help of setPixelSize method. In order to do this we use pixelSize method with the QFont object of the spin box

Syntax : font.pixelSize() Argument : It takes no argument Return : It returns integer

Below is the implementation 

Python3




# 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 pixel size
        font.setPixelSize(7)
 
        # 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 pixel size
        p_size = font.pixelSize()
 
        # setting text to the label
        label.setText("Pixel Size : " + str(p_size))
 
 
# create pyqt5 app
App = QApplication(sys.argv)
 
# create the instance of our Window
window = Window()
 
# start the app
sys.exit(App.exec())
