In this article we will see how we can get page step property 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.This property holds the single step. This property holds the page step. The larger of two natural steps that an abstract slider provides and typically corresponds to the user pressing PageUp or PageDown. For scroll bar page step increases the size of the slider up to some point, it can be set with the help of setPageStep method.

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

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 single step
        scroll.setPageStep(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 value changed signal
        scroll.valueChanged.connect(lambda: do_action())
 
        # method called when signal is emitted
        def do_action():
             
            # setting text to the label
            label.setText("Current Value : " + str(scroll.value()))
 
        # getting page step property
        value = scroll.pageStep()
 
        # setting text to the label
        label.setText("Page Step : " + str(value))
 
 
 
# create pyqt5 app
App = QApplication(sys.argv)
 
# create the instance of our Window
window = Window()
 
# start the app
sys.exit(App.exec())
