In this article we will see how we can step down the value of spin box using stepDown method, we can step up the value of spin box with the help of arrow button as well but in order to step down the value we use stepDown method. In order to do so we use stepDown method.
Syntax : spin_box.stepDown() Argument : It takes no argument Action performed : It decrement the value of spin box
Implementation steps : 1. Create a spin box 2. Create a push button 3. Add action to the push button 4. Inside the action call the stepDown method 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 , 250 , 40 )
# setting prefix to spin
self .spin.setPrefix("Prefix ")
# setting suffix to spin
self .spin.setSuffix(" Suffix")
# creating a push button
push = QPushButton("Press", self )
# setting geometry to the push button
push.setGeometry( 100 , 200 , 100 , 40 )
# adding action to the push button
push.clicked.connect( self .do_action)
# method called by push button
def do_action( self ):
# step down the value of spin box
self .spin.stepDown()
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
