PyQt5 - 访问单选按钮工具提示内容

在本文中，我们将了解如何访问单选按钮的工具提示内容。工具提示基本上是当我们将鼠标悬停在单选按钮上时出现的消息。工具提示提供提示并帮助用户更好地了解单选按钮。

为了访问单选按钮工具提示的内容，我们将使用toolTip方法

Syntax : radio_button.toolTip()

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 radio button
        self.radio_button = QRadioButton("Radio button", self)
  
        # setting geometry of radio button
        self.radio_button.setGeometry(200, 150, 120, 40)
  
        # setting tool tip
        self.radio_button.setToolTip("Click to make it check")
  
        # setting tool tip duration
        self.radio_button.setToolTipDuration(2000)
  
        # creating a label
        label = QLabel(self)
  
        # setting geometry of the label
        label.setGeometry(200, 200, 300, 30)
  
        # accessing the tool tip content
        content = self.radio_button.toolTip()
  
        # printing content through label
        label.setText(content)
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出：
