In this article we will see how we can set 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.
In order to do this we will use setAlternatingRowColors method with the list widget object. Syntax : list_widget.setAlternatingRowColors(True) Argument : It takes bool as argument Return : It returns None
Below is the implementation
Python3
# importing libraries from PyQt5.QtWidgets import * from PyQt5 import QtCore, QtGui from PyQt5.QtGui import * f rom 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("Lazyroar", self ) # setting geometry to the label label.setGeometry( 230 , 80 , 280 , 80 ) # making label multi line label.setWordWrap( True ) # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App. exec ()) |
