In this article we will see how we can scroll the spin box. Scrolling can be done by scrolling the pixels to right and scrolling pixels to downward. After scrolling, the widgets will receive paint events for the areas that need to be repainted. For spin box that Qt knows is to be opaque, this is only the newly exposed parts. For example, if an opaque spin box is scrolled 8 pixels to the left, only an 8-pixel wide stripe at the right edge needs updating.
Note : If spin box uses contents propagation, a scroll will cause an update of the entire scroll area.
In order to do this we use scroll method with the spin box object. 
 

Syntax : spin_box.scroll(right, down)
Argument : It takes two integer as 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, 250, 40)
 
        # setting range to the spin box
        self.spin.setRange(1, 999999)
 
        # setting prefix to spin
        self.spin.setPrefix("PREFIX ")
 
        # setting suffix to spin
        self.spin.setSuffix(" SUFFIX")
 
        # scrolling the spin box
        self.spin.scroll(-5, 6)
 
         
 
# create pyqt5 app
App = QApplication(sys.argv)
 
# create the instance of our Window
window = Window()
 
# start the app
sys.exit(App.exec())


Output :
