QT How to remove an action menu item

Question

when I add a widget to the main window, by default an action menu item will be displayed, how to remove it?

menuBar()->setVisible(false);

verAction = new QAction(tr("&Version"),this);
menuBar()->addAction(verAction);
connect(verAction, SIGNAL(triggered()),this, SLOT(displayVersion()));

displayAction = new QAction(tr("&Display"),this);
menuBar()->addAction(displayAction);


 connect(displayAction, SIGNAL(triggered()),this, SLOT(displayMessage()));

exitAction = new QAction(tr("&Exit"),this);
menuBar()->addAction(exitAction);
connect(exitAction, SIGNAL(triggered()),this, SLOT(close()));

thank

Answer 1

If you want to hide the QAction and display it when you need it, you can use the setVisible function .

If you want to remove the menu bar from QMainWindow, you can use the QT_NO_MENUBAR preprocessor to remove all uses of QMenuBar. If you are not using the tools provided by QMainWindow, perhaps you can use a simple QWidget as the main window in your application.

[] QActions , QMainWindow. , QAction actionTest, : this->ui->actionTest->setVisible(false);

QWidgetList widgets = QApplication::allWidgets();
QWidget* w=0;
foreach(w,widgets) {
    w->setContextMenuPolicy(Qt::NoContextMenu);
