You want to make the `QMenu` checkable or actions? AFAIK, `QMenu` can't be checkable. – Avaris Apr 29 '12 at 01:30

@Avaris yes I want the actions to be checkable. – unice Apr 29 '12 at 01:36

like this:
from PyQt4 import QtGui
app = QtGui.QApplication([])
w = QtGui.QMainWindow()
menu = QtGui.QMenu("menu", w)
menu.addAction(QtGui.QAction('50%', menu, checkable=True))
menu.addAction(QtGui.QAction('100%', menu, checkable=True))
menu.addAction(QtGui.QAction('200%', menu, checkable=True))
menu.addAction(QtGui.QAction('300%', menu, checkable=True))
menu.addAction(QtGui.QAction('400%', menu, checkable=True))
w.menuBar().addMenu(menu)
w.show()
app.exec_()
or witht radio buttons:
from PyQt4 import QtGui
app = QtGui.QApplication([])
w = QtGui.QMainWindow()
menu = QtGui.QMenu("menu", w)
ag = QtGui.QActionGroup(w, exclusive=True)
a = ag.addAction(QtGui.QAction('50%', w, checkable=True))
menu.addAction(a)
a = ag.addAction(QtGui.QAction('100%', w, checkable=True))
menu.addAction(a)
a = ag.addAction(QtGui.QAction('200%', w, checkable=True))
menu.addAction(a)
a = ag.addAction(QtGui.QAction('300%', w, checkable=True))
menu.addAction(a)
a = ag.addAction(QtGui.QAction('400%', w, checkable=True))
menu.addAction(a)
w.menuBar().addMenu(menu)
w.show()
app.exec_()

thank you very much for all the sample answers. That solves my problem. :) – unice Apr 29 '12 at 03:00

4I would add that you could use `myaction = QtGui.QAction('50%', menu, checkable=True)`, then `menu.addAction(myaction)` and eventually `myaction.isChecked()` to get the check status. – Giancarlo Sportelli Mar 20 '15 at 01:22

For anyone coming accross this thread, QActionGroup is [exclusive by default](https://doc.qt.io/qtforpython/PySide2/QtWidgets/QActionGroup.html) and you **do not** need to say ```exclusive=True``` – Carlos Medina Aug 22 '20 at 02:41

I suggest adding a few lines to the compact first solution to show the actual use of the buttons:
from PyQt4 import QtGui, QtCore
def isChecked():
""" Prints selected menu labels. """
[print(action.text()) for action in menu.actions() if action.isChecked()]
app = QtGui.QApplication([])
w = QtGui.QMainWindow()
menu = QtGui.QMenu("menu", w)
menu.addAction(QtGui.QAction('50%', menu, checkable=True))
menu.addAction(QtGui.QAction('100%', menu, checkable=True))
menu.addAction(QtGui.QAction('200%', menu, checkable=True))
menu.addAction(QtGui.QAction('400%', menu, checkable=True))
menu.triggered.connect(isChecked)
w.menuBar().addMenu(menu)
w.show()
app.exec_()

Example for with submenu for PyQt5
from PyQt5.QtWidgets import (
QMenu,
QAction,
)
menu = QMenu()
color_menu = QMenu('Player color')
white_color = QAction('White', checkable=True)
black_color = QAction('Black', checkable=True)
color_menu.addAction(white_color)
color_menu.addAction(black_color)
play_action = QAction('Start game')
menu.addAction(play_action)
