PyQt5 – 访问组合框的名称

在这篇文章中，我们将看到如何访问组合框的名称。名称基本上是用来区分组合框的，程序员可以根据它的用途来命名组合框，这样它们就很容易被区分。默认情况下，没有给组合框起名字。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。

语法： combo_box.accessibleName()

参数： 它不需要参数

返回： 它返回字符串

以下是实现方法

# importing libraries

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

        # 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"]

        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())
