In this article we will see how we can clear the text i.e value of the spin box, clearing doesn’t mean resetting the value means to revert back the original value, clearing the value/text means completely erase the content of the spin box. In order to do this we will use clear() method.

Syntax : spin_box.clear() Argument : It takes no argument Return : It returns None

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, 150, 40)
 
        # creating a push button
        button = QPushButton("Click", self)
 
        # setting geometry to the button
        button.setGeometry(200, 200, 100, 40)
 
        # adding action to the push button
        button.pressed.connect(self.do_something)
 
    # action called by the button
    def do_something(self):
 
        # clearing the spin box
        self.spin.clear()
 
 
 
# create pyqt5 app
App = QApplication(sys.argv)
 
# create the instance of our Window
window = Window()
 
# start the app
sys.exit(App.exec())
