PyQt5 - 访问组合框的名称

在本文中，我们将了解如何访问组合框的名称。名称基本上是用来区分组合框的，程序员可以根据组合框的用途来命名组合框，以便于区分。默认情况下，组合框没有名称。为了设置名称，我们使用setAccessibleName方法。

为了访问组合框的名称，我们使用accessibleName方法。

Syntax : combo_box.accessibleName()

Argument : It takes no argument

Return : It returns string

下面是实现

# 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, 150, 30)
  
        # geek list
        geek_list = ["Sayian", "Super Sayian"]
  
        # making it editable
        self.combo_box.setEditable(True)
  
        # adding list of items to combo box
        self.combo_box.addItems(geek_list)
  
        # name
        name = "Sayian Combo box"
  
        # setting name to the combo box
        self.combo_box.setAccessibleName(name)
  
        # getting the name
        get_name = self.combo_box.accessibleName()
  
        # creating label to show the name
        label = QLabel("Name :" + get_name, self)
  
        # setting geometry of the label
        label.setGeometry(200, 100, 200, 30)
          
          
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出：
