Remove top level QMenu from QMenubar programmatically

Question

I am working on a Python project that uses Qt Designer to build interface. when working on building a plugin capability, I was able to allow dynamic loading of user plugins and create a new QMenu item to add to the main menubar. The problem is that there seems to be no way of removing that top level QMenu once it is added to the main menubar. I researched/searched quite a bit on this topic and it seems that every solution related to this topic is for removing sub-menu items from a QMenu via removing its actions, not for removing that dynamically-added QMenu itself. I hope someone would point out this to be a simple thing, and provide a code snippet to demo how this is done.

Answer 1

Hope this will give you idea for what you upto. And I took some part from another post, which is same qmenu thing

import sys
# This is bad, but Iam lazy 
from PyQt4.QtCore import *
from PyQt4.QtGui import *

class MyWindow(QMainWindow):
    def __init__(self):
        super(MyWindow, self).__init__()
        self.main_menu = self.menuBar()
        widget = QWidget()
        self.menuList = []
        layout2 = QVBoxLayout(widget)
        self.menuButton = QPushButton("Add Menu")
        self.menuRmButton = QPushButton("Remove Menu")
        layout2.addWidget(self.menuButton)
        layout2.addWidget(self.menuRmButton)
        self.menuButton.clicked.connect(self.create_menu)
        self.menuRmButton.clicked.connect(self.removeMenu)
        self.setCentralWidget(widget)

    def create_menu(self):
        menu2 = self.main_menu.addMenu('Menu 1')
        self.menuList.append(menu2)
        Action1=QAction('Menu 1 0',self)
        Action1.triggered.connect(self.action_1)
        menu2.addAction(Action1)

        Action2=QAction('Menu 1 1',self)
        Action2.triggered.connect(self.action_2)
        menu2.addAction(Action2)

    def removeMenu(self):
        if self.menuList:
            for eachMenu in self.menuList:
                menuAct = eachMenu.menuAction()
                self.main_menu.removeAction(menuAct)
                # just for safe side
                menuAct.deleteLater()
                eachMenu.deleteLater()

    def action_1(self):
        print('Menu 1 0')

    def action_2(self):
        print('Menu 1 1')


if __name__ == '__main__':
    app=QApplication(sys.argv)
    new=MyWindow()
    new.show()
    app.exec_()

Achayan's solution above crashes on python2 qt4 (Windows) for the deletion

Better way for it is to to use the clear function.

Adding to the solution above,

def removeMenu():
    self.main_menu.clear()
