PyQt5 QSpinBox – Cleaning the text

In this article we will see how we can clean the text of the spin box, cleaning of the text means removing spacing and zeroes before any number as we know 001 is similar to the 1 therefore cleaning of text will remove the unwanted zeroes from the text.

In order to do this we use cleanText method.

Syntax : spin_box.cleanText()

Argument : It takes no argument

Action Performed : It cleans the text of spin box

Note : Prefix, suffix, or leading or trailing whitespace are excluded.

Implementation steps :
1. Create a main window
2. Create a spin box set its range prefix and suffix
3. Create a push button
4. Add action to the push button
5. Inside the action method call the cleanText method

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 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")

        # creating a push button
        push = QPushButton("Clean", self)

        # setting geometry to the push button
        push.setGeometry(100, 200, 100, 40)

        # adding action to the push button
        push.clicked.connect(self.push_action)


    # method called by the push button
    def push_action(self):

        # cleaning the text
        self.spin.cleanText()


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

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

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

Output :
