PyQt5 – QCommandLinkButton 类

QCommandLinkButton是 Windows Vista 引入的控件小部件。它的预期用途类似于单选按钮，因为它用于在一组互斥选项之间进行选择。它的外观通常类似于平面按钮，但除了普通按钮文本之外，它还允许使用描述性文本。默认情况下，它还会带有一个箭头图标，表示按下该控件将打开另一个窗口或页面或执行某些操作。下面是命令链接按钮的外观

例子 ：
我们将创建一个带有标签和命令链接按钮的窗口，当按下命令链接按钮时，计数器将在标签中增加

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):
  
        # counter value
        self.n = 0
  
        # creating label
        label = QLabel("Counter", self)
  
        # setting label geometry
        label.setGeometry(100, 100, 100, 40)
  
        # creating a command link button
        cl_button = QCommandLinkButton("Next", self)
  
        # setting geometry
        cl_button.setGeometry(200, 100, 200, 40)
  
        # adding action to the button
        cl_button.clicked.connect(lambda: increment(self.n))
  
  
        # method for incrementing the counter
        def increment(n):
              
            # increment
            self.n = n + 1
  
            # setting text to the label
            label.setText(str(self.n))
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
