In this article we will see how we can change the slider representation of QScrollBar. QScrollBar is a control that enables the user to access parts of a document that is larger than the widget used to display it. Slider is the scroll-able object inside the bar. There are basically four slider change options as follows: slider range change, slider orientation change, slider step change and slider value change.
 

In order to do this we will use sliderChange method with the scroll bar object.
Syntax : scroll.sliderChange(sliderchange)
Argument : It takes slider change object 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, 500, 400)
 
        # calling method
        self.UiComponents()
 
        # showing all the widgets
        self.show()
 
 
 
    # method for components
    def UiComponents(self):
 
        scroll = QScrollBar(self)
 
        # setting geometry of the scroll bar
        scroll.setGeometry(100, 50, 30, 200)
 
        # making its background color to green
        scroll.setStyleSheet("background : lightgrey;")
 
        # setting slider change
        scroll.sliderChange(QAbstractSlider.SliderOrientationChange)
 
 
        # creating a label
        label = QLabel("GeesforGeeks", self)
 
        # setting geometry to the label
        label.setGeometry(200, 100, 300, 80)
 
        # making label multi line
        label.setWordWrap(True)
 
 
 
 
# create pyqt5 app
App = QApplication(sys.argv)
 
# create the instance of our Window
window = Window()
 
# start the app
sys.exit(App.exec())

Output :
