PyQt5 QSpinBox – Step down the value using stepDown method
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 ()) |
