In this article we will see how we can get the alternation row color property 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. This property holds whether to draw the background using alternating colors. If this property is true, the item background will be drawn using QPalette.Base and QPalette.AlternateBase otherwise the background will be drawn using the QPalette.Base color. It can be set with the help of setAlternatingRowColors method.
In order to do this we will use alternatingRowColors method with the list widget object. Syntax : list_widget.alternatingRowColors() Argument : It takes no argument Return : It returns bool
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 , 60 )
# list widget items
item1 = QListWidgetItem("PyQt5 Geeks for Geeks")
item2 = QListWidgetItem("B")
item3 = QListWidgetItem("C")
# adding items to the list widget
list_widget.addItem(item1)
list_widget.addItem(item2)
list_widget.addItem(item3)
# setting alternating row color property
list_widget.setAlternatingRowColors( True )
# setting word wrap property
list_widget.setWordWrap( True )
# creating a label
label = QLabel("GeeksforGeeks", self )
# setting geometry to the label
label.setGeometry( 230 , 80 , 280 , 80 )
# making label multi line
label.setWordWrap( True )
# getting alternate row color property
value = list_widget.alternatingRowColors()
# setting text to the label
label.setText("Alternating Row Colors : " + str (value))
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
