PyQt5 QListWidget – Getting all Scroll Bar at given alignment

  • Last Updated : 18 Aug, 2020

In this article we will see how we can get the scroll bar of the QListWidget at the given alignment. 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. Scroll bar can be added to list widget at the specific alignment with the help of addScrollBarWidget method.

In order to do this we will use scrollBarWidgets method with the list widget object.

Syntax : list_widget.scrollBarWidgets(alignment)

Argument : It takes QAlignment object as argument

Return : It returns list of QScrollBar widgets



Below is the implementation




# 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):
  
        # 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;")
  
        # adding extra scroll bar to it
        list_widget.addScrollBarWidget(scroll_bar, Qt.AlignLeft)
  
        # creating a label
        label = QLabel("GeesforGeeks", self)
  
        # setting geometry to the label
        label.setGeometry(230, 80, 280, 80)
  
        # making label multi line
        label.setWordWrap(True)
  
        # getting scroll bar at right alignment
        value = list_widget.scrollBarWidgets(Qt.AlignRight)
  
        # setting text to the label
        label.setText(" Scroll Bar : " + str(value))
  
  
  
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
