PyQt5 - 获取单选按钮标题的程序

在本文中，我们将了解如何获取单选按钮的文本（标题）。当我们创建单选按钮时，我们为其设置了一些文本，在setText方法的帮助下，我们可以更新其中的文本。

Overview of the implementation:

1. We will create a radio button.
2. Set some text to the radio button with the help of setText method.
3. Retrieve the text and save it the variable with the help of text method.
4. Create a label and set the retrieved text to it.

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
        radio_button = QRadioButton(self)
  
        # setting geometry of radio button
        radio_button.setGeometry(200, 150, 120, 40)
  
        # setting text to radio button
        radio_button.setText("GEEK Radio button ")
  
        # get the text of radio button
        text = radio_button.text()
  
        # create label to display the text
        label = QLabel(self)
  
        # set text to label
        label.setText("Caption of radio button is  : " + text)
  
        # set the geometry of label
        label.setGeometry(180, 200, 300, 30)
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
