PyQt5 – Count the number of items in ComboBox

Last Updated : 22 Apr, 2020

In this article we will see how we can find the total number of items present in the combo box. We know we can add items in the combo box with the help of addItem method to add single item and addItems method to add multiple items. In order to get the count of all the items in the combo box we will use count method.

Syntax : combo_box.count()
Argument : It takes no argument
Return : It will return integer i.e number of items in combo box

Steps for implementation:

1. Create a combo box
2. Add items to combo box
3. Create push button
4. Add action to the push button
5. Create label to show count
5. Inside the action count the items of combo box with the help of count method and store it in variable
6. Show the count variable in label with the help of setText method

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, 600, 400)
  
        # calling method
        self.UiComponents()
  
        # showing all the widgets
        self.show()
  
    # method for widgets
    def UiComponents(self):
  
        # creating a combo box widget
        self.combo_box = QComboBox(self)
  
        # setting geometry of combo box
        self.combo_box.setGeometry(200, 150, 120, 30)
  
        # geek list
        geek_list = ["Geek", "Geeky Geek", "Legend Geek", "Ultra Legend Geek"]
  
        # adding list of items to combo box
        self.combo_box.addItems(geek_list)
  
        # creating push button to clear the list
        button = QPushButton("Find Count ", self)
  
        print(self.combo_box.count())
  
        # adding action to button
        button.pressed.connect(self.find_count)
  
        # creating label to show count
        self.label = QLabel(self)
  
        # setting geometry of the label
        self.label.setGeometry(200, 200, 200, 30)
  
    def find_count(self):
  
        # finding the number of items in cmbo box
        count = self.combo_box.count()
  
        # showing count on the screen though label
        self.label.setText("Total number of  items : " + str(count))
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
