PyQt5 QSpinbox – Accessing the line edit object of it

In this article we will see how we can access the line edit object of the spin box, line edit is widget in PyQt5 which is used to display text and accept the input text. By default spin box has its own line edit object although we can add our own line edit object to it with the help of setLineEdit method.

In order to do this we use lineEdit method

Syntax : spin_box.lineEdit()

Argument : It takes no argument

Return: It returns line edit object

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 prefix to spin
        self.spin.setPrefix("Prefix ")

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

        # get the line edit object of spin box
        line = self.spin.lineEdit()

        # creating a label
        label = QLabel(self)

        # setting text to the label
        label.setText(str(line))

        # adjust the size of the label
        label.adjustSize()



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

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

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

Output :
