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);

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.
