PyQt5 QScrollBar – Getting Slider Position

In this article we will see how we can get position of slider in 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. We can change its position with the help of mouse and keyboard. Also we can change its position programmatically with the help of setSliderPosition method.

In order to do this we will use sliderPosition method with the scroll bar object.
Syntax : scroll.sliderPosition()
Argument : It takes no argument
Return : It returns integer 

Example: 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 position
        scroll.setSliderPosition(50)


        # creating a label
        label = QLabel("GeeksforGeeks", self)

        # setting geometry to the label
        label.setGeometry(200, 100, 300, 80)

        # making label multi line
        label.setWordWrap(True)

        # getting current position of the slider
        value = scroll.sliderPosition()

        # setting text to the label
        label.setText("Slider Position : " + str(value))





# create pyqt5 app
App = QApplication(sys.argv)

# create the instance of our Window
window = Window()

# start the app
sys.exit(App.exec())

Output :
