pyqt5 menu

To design a menu for a PyQt5 application, utilizing QMainWindow is essential.
This type of menu can be observed in many applications and it displays right beneath the window bar, typically comprising of sub-menus like ‘file’ and ‘edit’.

The primary menu in PyQt5 can be constructed using the menuBar() method.
Sub-menus can be effortlessly integrated using the addMenu(name) function.
Here’s a simple demonstration:

mainMenu = self.menuBar()
fileMenu = mainMenu.addMenu('File')
editMenu = mainMenu.addMenu('Edit')
viewMenu = mainMenu.addMenu('View')
searchMenu = mainMenu.addMenu('Search')
toolsMenu = mainMenu.addMenu('Tools')
helpMenu = mainMenu.addMenu('Help')

Furthermore, individual menu items or buttons can be incorporated into these menus.
Below is an example of how to integrate an ‘Exit’ button:

exitButton = QAction(QIcon('exit24.png'), 'Exit', self)
exitButton.setShortcut('Ctrl+Q')
exitButton.setStatusTip('Exit the software')
exitButton.triggered.connect(self.close)
fileMenu.addAction(exitButton)

The button action is then connected using a pyqtslot.

import sys
from PyQt5.QtWidgets import QMainWindow, QApplication, QWidget, QPushButton, QAction
from PyQt5.QtGui import QIcon
from PyQt5.QtCore import pyqtSlot

class App(QMainWindow):
  
    def __init__(self):
        super().__init__()
        self.title = 'PyQt5 interactive menu tutorial - pythonspot.com'
        self.left = 10
        self.top = 10
        self.width = 640
        self.height = 400
        self.initUI()
  
    def initUI(self):
        self.setWindowTitle(self.title)
        self.setGeometry(self.left, self.top, self.width, self.height)
      
        mainMenu = self.menuBar()
        fileMenu = mainMenu.addMenu('File')
        editMenu = mainMenu.addMenu('Edit')
        viewMenu = mainMenu.addMenu('View')
        searchMenu = mainMenu.addMenu('Search')
        toolsMenu = mainMenu.addMenu('Tools')
        helpMenu = mainMenu.addMenu('Help')
      
        exitButton = QAction(QIcon('exit24.png'), 'Exit', self)
        exitButton.setShortcut('Ctrl+Q')
        exitButton.setStatusTip('Terminate the program')
        exitButton.triggered.connect(self.close)
        fileMenu.addAction(exitButton)
  
        self.show()
  
if __name__ == '__main__':
    app = QApplication(sys.argv)
    ex = App()
    sys.exit(app.exec_())
