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
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 ): # 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 ) # 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 ()) |
Output :
