PyQt5 - 在 ComboBox 中的给定索引处添加多个项目

在本文中，我们将看到如何在给定索引处的组合框中添加多个项目。我们知道我们可以在 addItem 和 addItems 方法的帮助下添加项目，但是项目只在最后添加，为了在给定索引处添加多个项目，我们使用 insertItems 方法。

Syntax : combo_box.insertItems(index, item_list)
Argument : It takes two argument one is integer i.e index and second is list i.e list with each element is string
Action performed : It will add items at the given index 
 

下面是实现——

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, 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)
 
        # new item list
        new = ["One", "two", "three"]
         
        # adding item list at index 0
        self.combo_box.insertItems(0, new)
 
# create pyqt5 app
App = QApplication(sys.argv)
 
# create the instance of our Window
window = Window()
 
# start the app
sys.exit(App.exec())

输出 ：
