PyQt5 QListWidget – Getting Alternating Row Color property

0 0 1 minute read

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

Python3

# importing libraries
from PyQt5.QtWidgets import *
from PyQt5 import QtCore, QtGui
from PyQt5.QtGui 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("zambiatek", 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())
