In this article we will see how we can change the value of spin box using setBy method, we can step up the value of spin box with the help of arrow button as well but in order to change the value we use setBy method, this method add the passed value to the current value.
In order to do so we use setBy method.
Syntax : spin_box.setBy(n)
Argument : It takes integer as argument
Action performed : It change 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 stepBy method
Below is the implementation
# importing librariesfrom PyQt5.QtWidgets import * from PyQt5 import QtCore, QtGuifrom 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): # change value by 5 steps self.spin.stepBy(5) # create pyqt5 appApp = QApplication(sys.argv) # create the instance of our Windowwindow = Window() # start the appsys.exit(App.exec()) |
