In this article we will see how we can change the content of item at the specific index in combo box. In order to do this we will use setItemText method.

Syntax : combo_box.setItemText(index, item)

Argument : It takes two argument one is integer and second is string

Action performed : This will change the content at that specific index

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 previous text
5. Inside the action change the content of item at given index using setItemText 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
        button = QPushButton("Change content ", self)
  
        print(self.combo_box.count())
  
        # adding action to button
        button.pressed.connect(self.find)
  
        # creating label
        self.label = QLabel(self)
  
        # setting geometry of the label
        self.label.setGeometry(200, 200, 200, 30)
  
        # old content at index 2
        content = self.combo_box.itemText(2)
  
        # showing the old content
        self.label.setText("old content  : content")
  
    def find(self):
  
        # index
        index = 2
  
        # changing the content
        self.combo_box.setItemText(index, "New data")
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
