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 librariesfrom PyQt5.QtWidgets import *from PyQt5 import QtCore, QtGuifrom PyQt5.QtGui import *from PyQt5.QtCore import *import sysclass 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 appApp = QApplication(sys.argv)# create the instance of our Windowwindow = Window()# start the appsys.exit(App.exec()) |
Output :
