QMenu mac

[migel]

Any idea how to add an QAction into mac menubar ? Mac has default first menu named as name of the application, it appears on menubar as first on left. I want to add an action there but the code below seems not working.

QAction *b1 = new QAction(tr("Check for Updates"), this);
    _ui->menubar->addAction(b1);
    connect(b1, SIGNAL(triggered()), this, SLOT(checkForUpdates()));

QAction *b1 = new QAction(tr("Check for Updates"), this);
    _ui->menubar->addAction(b1);
    connect(b1, SIGNAL(triggered()), this, SLOT(checkForUpdates()));

To copy to clipboard, switch view to plain text mode 

I have created default mainwindow.ui form.

Any ideas ?

Thanks for help.
