PyQt5 QCommandLinkButton – 设置菜单

在本文中，我们将看到如何将菜单设置为 QCommandLinkButton。菜单基本上是命令链接按钮的一个额外功能，它允许它有一个下拉菜单，用户可以从中单击菜单项。下面是命令链接按钮的样子

为了做到这一点，我们使用setMenu方法和命令链接按钮对象

Syntax : button.setMenu(menu)

Argument : It takes QMenu object as argument

Return : It return None

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(200, 100, 150, 60)
  
        # QActions
        a = QAction("Next Geeks", self)
        b = QAction("Previous Geeks", self)
  
        # QMenu
        menu = QMenu()
  
        # adding actions to menu
        menu.addAction(a)
        menu.addAction(b)
  
        # setting menu to the button
        cl_button.setMenu(menu)
  
  
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出 ：
