In this article we will see how we can get the vertical scroll bar of the QListWidget. QListWidget is a convenience class that provides a list view with a classic item-based interface for adding and removing items. QListWidget uses an internal model to manage each QListWidgetItem in the list. Setting vertical scroll bar replaces the existing vertical scroll bar with scrollBar, and sets all the former scroll bar’s slider properties on the new scroll bar. The former scroll bar is then deleted. It can be set with the help of setVerticalScrollBar method.
In order to do this we will use verticalScrollBar method with the list widget object. Syntax : list_widget.verticalScrollBar() Argument : It takes no argument Return : It returns QScrollBar object
Below is the implementation
Python3
# importing librariesfrom PyQt5.QtWidgets import *from PyQt5 import QtCore, QtGuifrom PyQt5.QtGui import *from PyQt5.QtCore import *import sysclass 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): # creating a QListWidget list_widget = QListWidget(self) # setting geometry to it list_widget.setGeometry(50, 70, 150, 80) # list widget items item1 = QListWidgetItem("PyQt5 Geeks for Geeks") item2 = QListWidgetItem("B") item3 = QListWidgetItem("C") item4 = QListWidgetItem("D") # adding items to the list widget list_widget.addItem(item1) list_widget.addItem(item2) list_widget.addItem(item3) list_widget.addItem(item4) # scroll bar scroll_bar = QScrollBar(self) # setting style sheet to the scroll bar scroll_bar.setStyleSheet("background : lightgreen;") # setting vertical scroll bar to it list_widget.setVerticalScrollBar(scroll_bar) # creating a label label = QLabel("Lazyroar", self) # setting geometry to the label label.setGeometry(230, 80, 280, 80) # making label multi line label.setWordWrap(True) # getting vertical scroll bar value = list_widget.verticalScrollBar() # setting text to the label label.setText("Vertical Scroll Bar : " + str(value))# create pyqt5 appApp = QApplication(sys.argv)# create the instance of our Windowwindow = Window()# start the appsys.exit(App.exec()) |
Output :
