In this article we will see how we can clear all the items 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 delete all the items in the combo box we will use clear method.

Syntax : combo_box.clear()

Argument : It takes no argument

Action performed : It will delete all the items of 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. Inside the action delete the items of combo box with the help of clear 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):
        # setting title
        self.setWindowTitle("Python ")
        # setting geometry
        self.setGeometry(100, 100, 600, 400)
        # calling method
        # showing all the widgets
    # 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
        # creating push button to clear the list
        button = QPushButton("Clear", self)
        # adding action to button
    def delete(self):
        # delete items of list
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
