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 ())
