PyQt5 – 如何向 ComboBox 添加多个项目？

在本文中，我们将看到如何一次将多个项目添加到组合框中。我们知道我们可以在 addItem 方法的帮助下将项目添加到组合框中，但此方法一次只能添加单个项目。为了一次添加多个项目，我们必须使用 addItems 方法一次添加所有项目，而不是一个一个地添加。

Syntax : combo_box.addItems(item_list)
Argument : It takes list as argument
Action performed : It will add all the list item to the combo box

编程需要懂一点英语

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
        combo_box = QComboBox(self)
 
        # setting geometry of combo box
        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
        combo_box.addItems(geek_list)
 
# create pyqt5 app
App = QApplication(sys.argv)
 
# create the instance of our Window
window = Window()
 
# start the app
sys.exit(App.exec())

输出：
