How to add a separator to the menu bar?

NonNT

# Menu: View
menuView = self.menuBar().addMenu('View')
...

# Separator
menuSeparator = self.menuBar().addMenu('|')
menuSeparator.setEnabled(False)

# Menu: Help
menuHelp = self.menuBar().addMenu('Help')
...

Is this the only way to add a separator to the menu bar?

Thanks

As far as I know QMenuBar has an addSeparator function.
https://doc.qt.io/qt-5/qmenubar.html#addSeparator

Yeah, I know. I've tried it before, but it doesn't work.

KDevelop uses separators in the menu bar and they use actions for that

kdevelop/kdevplatform/shell/mainwindow.cpp:

    //KDevelop needs to ensure that separators defined as <Separator style="visible" />
    //are always shown in the menubar. For those, we create special disabled actions
    //instead of calling QMenuBar::addSeparator() because menubar separators are ignored
    if (element.tagName().compare(QLatin1String("separator"), Qt::CaseInsensitive) == 0
            && element.attribute(QStringLiteral("style")) == QLatin1String("visible")) {
        if ( auto* bar = qobject_cast<QMenuBar*>( parent ) ) {
            auto* separatorAction = new QAction(QStringLiteral("|"), this);
            bar->insertAction( before, separatorAction );
            separatorAction->setDisabled(true);
            return separatorAction;
        }
    }

According to https://www.qtcentre.org/threads/13910-why-addSeparator()-doesn-t-work-on-QMenuBar, from 2008(!), this depends on the style you use....

If KDevelop does their workaround, I guess that's the way you should go....

I use KDE Breeze.

And QAction('|', self) is the better choice than addMenu('|') because in a vertical menuBar deactivated QAction disappear while addMenu('|') doesn't look so nice.

But in a horizontal menuBar both look the same.

I still found this:

We create the Tools, Options, and Help menus in a similar fashion.
We insert a separator between the Options and Help menus. 
In Motif and CDE styles, the separator pushes the Help menu to the right;
in other styles, the separator is ignored. Figure 3.5 shows both cases.

That is why I pointed you at https://www.qtcentre.org/threads/13910-why-addSeparator()-doesn-t-work-on-QMenuBar and said it depends on the style you use.
