PyQt5 QCommandLinkButton – 获取描述文本

在本文中，我们将了解如何获取 QCommandLinkButton 的描述文本。描述文本属性包含一个描述性标签以补充命令链接按钮文本。设置此属性将在按钮上设置描述性文本，补充文本标签。这通常会以比主要文本更小的字体显示。它可以在setDescription方法的帮助下添加。

为了做到这一点，我们使用带有命令链接按钮对象的description方法

Syntax : button.description()

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, 500, 400)
  
        # calling method
        self.UiComponents()
  
        # showing all the widgets
        self.show()
  
    # method for components
    def UiComponents(self):
  
        # creating a command link button
        cl_button = QCommandLinkButton("Press", self)
  
        # setting geometry
        cl_button.setGeometry(250, 100, 200, 50)
  
        # text
        text = "GeeksforGeeks"
          
        # setting description text
        cl_button.setDescription(text)
  
        # creating label
        label = QLabel("GeeksforGeeks", self)
  
        # setting label geometry
        label.setGeometry(50, 100, 200, 80)
  
        # making label multiline
        label.setWordWrap(True)
  
        # getting description text
        value = cl_button.description()
  
        # setting text to the label
        label.setText("Description Text : " + str(value))
  
  
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出 ：
