PyQt5 QSpinBox - How to get the parent

Last Updated : 28 May, 2020

In this article we will see how we can get the parent of the spin box. Each widget has some parent for example Spin box's child is line edit and line edit parent will be the spin box itself. In order to do this we use parent method with the spin box object.

Syntax : spin_box.parent() Argument : It takes no argument Return : It returns parent object

Below is the implementation

Python3 1==

# 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(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 parent
        value = self.spin.parent()

        # setting text to the label
        label.setText("Parent : " + str(value))


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

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

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