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
# 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 ())
