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
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) # setting batch size list_widget.setBatchSize( 20 ) # creating a label label = QLabel("neveropen", 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 ()) |
Output :
