How do I hide a sub-menu in QMenu

Question

I have an application where I generate menu items, and I want to set the visibility of a particular sub-menu.

I tried using setVisibility(False), but this did not work. setVisibility() works for menu items, but not for sub-menus in QMenus.

Have a look at the code snippet below:

import sys
from PyQt4 import QtGui

class Window(QtGui.QWidget):
    def __init__(self, parent=None):
        super(Window, self).__init__(parent)
        self.menu = QtGui.QMenu()
        self.actio1 = QtGui.QAction('One', self)
        self.actio2 = QtGui.QAction('Two', self)
        self.menu.addAction(self.actio1)
        self.menu.addAction(self.actio2)
        self.actio1.setVisible(False)
        self.submenu = QtGui.QMenu('submenu', self)
        self.submenu.addAction('sub one')
        self.submenu.addAction('sub two')
        self.menu.addMenu(self.submenu)        
        self.submenu2 = QtGui.QMenu('submenu 2', self)
        self.submenu2.addAction('sub 2 one')
        self.submenu2.addAction('sub 2 two')
        self.menu.addMenu(self.submenu2)        
        self.submenu2.setVisible(False)
        layout = QtGui.QHBoxLayout()
        layout.addWidget(self.menu)
        self.setLayout(layout)

if __name__ == '__main__':

    app = QtGui.QApplication(sys.argv)
    w = Window()
    w.show()
    sys.exit(app.exec_())

In the above example, I can hide the menu item named "One", but not the sub-menu named "submenu 2"

Can anyone give me an idea...

Answer 1

You very nearly had it;

Instead of this:

self.submenu2.setVisible(False)

You want this:

self.submenu2.menuAction().setVisible(False)
