PyQt5 QListWidget – Setting Style Sheet

Last Updated : 09 Feb, 2023

In this article we will see how we can set style sheet to 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. Style sheet is the properties which are used to make the appearance better i.e by creating customized design. It can be set with the help of setStyleSheet method.

In order to do this we will use setStyleSheet method with the list widget object. Syntax : list_widget.setStyleSheet(sheet) Argument : It takes string as argument Return : It returns None

Below is the example style sheet code

QListWidget
{
border : 2px solid black;
background : lightgreen;
}
QListWidget QScrollBar
{
background : lightblue;
}
 QListView::item:selected
{
border : 2px solid black;
background : green;
}

Below is the implementation

Python3

# importing libraries
from PyQt5.QtWidgets import * 
from PyQt5 import QtCore, QtGui

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)

        # setting style sheet
        list_widget.setStyleSheet("QListWidget"
                                  "{"
                                  "border : 2px solid black;"
                                  "background : lightgreen;"
                                  "}"
                                  "QListWidget QScrollBar"
                                  "{"
                                  "background : lightblue;"
                                  "}"
                                  "QListView::item:selected"
                                  "{"
                                  "border : 2px solid black;"
                                  "background : green;"
                                  "}"
                                  )

        # 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)




# create pyqt5 app
App = QApplication(sys.argv)

# create the instance of our Window
window = Window()

# start the app
sys.exit(App.exec())
