PyQt5 QListWidget – Setting Uniform Item Sizes Property

0 0 1 minute read

In this article we will see how we can set uniform item sizes property 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 whether all items in the listview have the same size. This property should only be set to true if it is guaranteed that all items in the view have the same size. This enables the view to do some optimizations for performance purposes.

In order to do this we will use setUniformItemSizes method with the list widget object. Syntax : list_widget.setUniformItemSizes(True) Argument : It takes bool 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 uniform item size
        list_widget.setUniformItemSizes(True)
 
        # creating a label
        label = QLabel("zambiatek", 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())
