PyQt5 - 单击时更改单选按钮中的文本

在本文中，我们将了解如何更改单选按钮中的文本。当我们创建单选按钮时，我们设置了一些文本，甚至可以将其留空，单选按钮是在QRadioButton类的帮助下创建的。

我们将创建一个单选按钮和一个按钮，这样当按下按钮时，单选按钮文本应该被更改。

In order to do so we have to do the following –

Create a radio button.
Create a push button.
Connect a method associated with push button, such that when push button get pressed this method should get called.
In the method change the radio button content with the help of setText method.

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 radio button
        self.button1 = QRadioButton("Button1", self)
  
        # setting geometry of radio button
        self.button1.setGeometry(200, 150, 100, 40)
  
        # creating push button
        self.push = QPushButton("Change the text ", self)
  
        # setting geometry of push button
        self.push.setGeometry(200, 200, 100, 40)
  
        # connect push button to method
        self.push.clicked.connect(self.changeName)
  
    # creating changeName method
    def changeName(self):
  
        # setting new text to radio button
        self.button1.setText("New Name")
  
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出：
