setContextMenuPolicy not working with QKeySequenceEdit

reonZ

No matter which Qt::ContextMenuPolicy i choose for setContextMenuPolicy of my QKeySequenceEdit, i always get the default windows text edit context menu: alt text

I tried everything ,Qt::NoContextMenu, Qt::PreventContextMenu, Qt::ActionsContextMenu while adding actions and Qt::CustomContextMenu while using a connect to customContextMenuRequested and nothing changes.

Hi
Yes, it seemed odd at first so i checked the source.
https://code.woboq.org/qt5/qtbase/src/widgets/widgets/qkeysequenceedit.cpp.html
Its using a internal LineEdit so thats the one we click on and hence the ContextMenuPolicy
of the actual QKeySequenceEdit is not really used.

Knowing this we can do

KeySequenceEdit *seqEdit = new QKeySequenceEdit(centralWidget());
    QLineEdit *LineEdit = seqEdit->findChild<QLineEdit *>();
    if (LineEdit) {
        LineEdit->setContextMenuPolicy(Qt::CustomContextMenu);
        connect(LineEdit, &QLineEdit::customContextMenuRequested, [this](QPoint pos) {
            QMenu *menu = new QMenu(this);
            menu->addAction(new QAction("Action 1", this));
            menu->addAction(new QAction("Action 2", this));
            menu->addAction(new QAction("Action 3", this));
            menu->popup(this->mapToGlobal(pos)); // this might not be excact.
        });
    }

Note this is slightly dirty as we use a private widget. ;)

@mrjj Arf i knew it would be something like this and i even tried to look for it on my own, sadly i am not experienced enough to go and read sources like you did, thanks really.

Also what do you mean by Note this is slightly dirty as we use a private widget ?

And lastly, is there a way for me to add actions to the default context menu ? the one from the screenshot in my OP.

P.S.: i prefer using Qt::ActionsContextMenu, i don't have to create a menu and connect and the popup is placed automatically at the right position.

Hi
Well the wobog browser makes it easy to dig around as all is hot linked.
So you just go to https://code.woboq.org/qt5/ and type the class name in the search field.

Also what do you mean by "Note this is slightly dirty as we use a private widget ?"
That the LineEdit is not surfaced through any method so we use insider knowledge
of the class and find a way to access it. if it was ever changed, our code would break.
But that is very unlikely. :)

-is there a way for me to add actions to the default context menu ?
Yes, you can use
http://doc.qt.io/qt-5/qlineedit.html#createStandardContextMenu
and then add yours to that.
