In this article we will see how we can add extra 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. Adds widget as a scroll bar widget in the location specified by alignment. Scroll bar widgets are shown next to the horizontal or vertical scroll bar, and can be placed on either side of it. If you want the scroll bar widgets to be always visible, set the scrollBarPolicy for the corresponding scroll bar to AlwaysOn.
In order to do this we will use addScrollBarWidget method with the list widget object. Syntax : list_widget.addScrollBarWidget(scrollbar, alignment) Argument : It takes QScrollBar and QAlignment object as argument Return : It returns None
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;") # adding extra scroll bar to it list_widget.addScrollBarWidget(scroll_bar, Qt.AlignLeft) # creating a label label = QLabel("neveropen", self) # setting geometry to the label label.setGeometry(230, 80, 280, 80) # making label multi line label.setWordWrap(True)# create pyqt5 appApp = QApplication(sys.argv)# create the instance of our Windowwindow = Window()# start the appsys.exit(App.exec()) |
Output :
