In this article we will see how we can get the batch size 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 number of items laid out in each batch if layoutMode is set to Batched. The default value is 100 although it can be changed any time with the help of setBatchSize method.
In order to do this we will use batchSize method with the list widget object. Syntax : list_widget.batchSize() Argument : It takes no argument Return : It returns integer
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)
# setting batch size
list_widget.setBatchSize( 20 )
# 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 )
# getting batch size
value = list_widget.batchSize()
# setting text to the label
label.setText("Batch Size : " + str (value))
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
