Qt5: How to hide or remove a QMenu from the QMenuBar?

Question

I am using Qt5 on Windows7 platform:
Qt Creator version is: v3.3.2.
Qt version 5.5.1 and MinGW 32bit.

Currently, in the menu bar I have:

Configuration - Reports - Help

I searched SO and I found this as a possible answer: Not possible to hide a QMenu object QMenu::setVisible()?, but it didn't work...

So, I was trying to remove the Help menu using:

ui->menuHelp->setVisible(false);

and:

ui->menuHelp->menuAction()->setVisible(false);

Unfortunatelly, both failed to hide/remove the Help menu...

Please, is there any other way to do it?

[Code]:

MainWindow::MainWindow(QWidget * parent) :
    QMainWindow(parent),
    ui(new Ui::MainWindow)
{
    ui->setupUi(this);
    this->setWindowFlags(this->windowFlags() & ~Qt::WindowMaximizeButtonHint);
    if(!server.listen(QHostAddress("192.168.1.2"), 8001))
        return;
    if(true) // just testing...
       ui->menuHelp->menuAction()->setVisible(false);
}

Just for test, I've added 3 menus to menuBar.
Then I tried this:

ui->menu3->menuAction()->setVisible(false);

And it worked like expected - it hides menu3. Your problem is somewhere else.

The code ui->menuHelp->setVisible(false); hides the menu, not the action on menuBar. For example when you click on action on menuBar the menu becomes visible. Then you can hide it with this line of code. But when you call this directly from constructor the menu is still invisible, so this code does nothing.
