PyQt5 QListWidget - Setting Layout Mode

Last Updated : 02 Feb, 2023

In this article we will see how we can set the layout mode 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 the layout mode for the items. When the mode is SinglePass (the default), the items are laid out all in one go. When the mode is Batched, the items are laid out in batches of batchSize items, while processing events. This makes it possible to instantly view and interact with the visible items while the rest are being laid out.

In order to do this we will use setLayoutMode method with the list widget object.

Syntax : list_widget.setLayoutMode(mode)

Argument : It takes layout mode object 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 * 
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("A")
        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 layout mode
        list_widget.setLayoutMode(QListView.Batched)

        # 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())
