default popup of menubar / mainwindow

hi

when you right click on menubar of mainwindow, you see a default popup, shows a checkable list of visible widgets of mainwindow (enable you to show or hide them separately).

there is no contextmenu event code in your code (to access it) and also i didnt find it in qt help.

how can i show the proposed popup(, when click on an item of menubar [NOT right click!])?

How about using QMainWindow::createPopupMenu (). :rolleyes:

thanks,

is there a way to catch click on menubar items (NOT their subitems / actions)?
i cant find signal for it and prefer not use mouse event handling routine.

it has down with installing event filter for the item of menubar :

Code:

---

bool MainWindow::eventFilter(QObject *obj, QEvent *event)
{
    static bool _bjust_created = false;
    static QMenu * menu;
 
    //menuBar has menuFile, menuView, menuHelp
    if(obj != ui->menuView) {
        _bjust_created =false;
        ui->menuView->clearFocus();
        menu->close();
        return true;
    }
    event->accept();
    if(!_bjust_created)
      if ((event->type() == QEvent::MouseMove)||
          (event->type() == QEvent::MouseButtonPress)) {
        menu = createPopupMenu ();
        menu->exec(ui->menuView->pos());
        _bjust_created = true;
      }
    ui->menuView->clearFocus();
    return true;
}

it shows PopupMenu at good position, but after exit of mouse from menuView area,
I have to do a click in other region to disappear the PopupMenu and also
the menuView remain focused and other menuBar items / widgets cant be accessed via mouse.

where is the problem? what is solution?

i found that problem is raised from

Code:

---

MainWindow::MainWindow(QWidget *parent)
                       : QMainWindow(parent), ui(new Ui::MainWindow)
{
ui->setupUi(this);
ui->menuView->installEventFilter(this);
//does not work: ui->menuView->installEventFilter(parent);
//does not work: ui->menuView->installEventFilter(ui->menuView);
}
