        QMenuBar *menuBar;
        QMenu *menuFile;
        QAction *actionOpen;
        QAction *actionClose;

        menuBar = new QMenuBar(MainWindow);

        menuFile = new QMenu(menuBar);
        menuFile->setTitle("File");

        actionOpen = new QAction(MainWindow);
        actionOpen->setText("Open");

        actionClose = new QAction(MainWindow);
        actionClose->setText("Close");

        menuBar->addAction(menuFile->menuAction());
        menuFile->addAction(actionOpen);
        menuFile->addAction(actionClose);
        @

        To disable one of the items or whole "File" menu
        @
        actionOpen->setEnable(false);
        menuFile->setEnable(false);
        @

        To enable them back
        @
        actionOpen->setEnable(true);
        menuFile->setEnable(true);

          Approaching like this would disables the QMenu, and it's children are no longer visible. Is there is a way in which the user can see that ta QMenu is disable but still can see it's children?

          menuFile->setEnable(false);

            In the same way, You can disable all the sub menus and enable the main menu.
