How to use same context menu on two QDateEdit objects?

[Mucip]

Hi,
I have two DateEdit in same window. Unfotunatelly we can not set empty date on this QDateEdit object and I really wonder why?!... :(

I plant use contextmenu for these DateEdits "Reset Date" which is reset date to 01.01.2000 and "Today" which is set date to today's date.

I use context menu like below:

//Ters Tuş menüsü Tarih İşlem...
    ui->dateIslem->setContextMenuPolicy(Qt::CustomContextMenu);
         connect(ui->dateIslem, SIGNAL(customContextMenuRequested(const QPoint&)),
                    this, SLOT(ShowContextMenuTarih(const QPoint&)));

And the function is:

void BakimOnarim::ShowContextMenuTarih(const QPoint &pos)
{

    QPoint globalPos = ui->dateIslem->mapToGlobal(pos);

    QMenu myMenu;

    myMenu.addAction("Reset Date");
    myMenu.addAction("Today");





    QAction* selectedItem = myMenu.exec(globalPos);

    // Hiçbir şey tıklanmazsa hata vermesin diye... :)

    if (selectedItem == nullptr) return;



    if (selectedItem->text() == "Reset Date" )
    {
       ui->dateIslem->setDate(QDate::fromString("2000-01-01","yyyy-MM-dd"));
    }

    else if (selectedItem->text() == "Today" )
    {
        ui->dateIslem->setDate(QDate::currentDate());
    };

}

But the problem is I have two or maybe more DateEdit on the same form. Well I want to use same context menu on many deteEdits!

I need to use SENDER like specification which is target to sender object. And sender object need to be use same context menu?!

Any help?!...

P.S.: I wish Qt would permit empty date do DateEdit. :(

Why can't you call the same slot for the second QDateEdit?

Hi @Christian-Ehrlicher ,
But there is belowed line in the context menu slot:

QPoint globalPos = ui->dateIslem->mapToGlobal(pos);

Well How can I change to dateIslem, dateZaman, dateBitis ...

Or maybe I lost something?!...

@Mucip said in How to use same context menu on two QDateEdit objects?:

QPoint globalPos = ui->dateIslem->mapToGlobal(pos);

See https://doc.qt.io/qt-5/qobject.html#sender

@Christian-Ehrlicher ,
It looks that sender doesn't have "->mapToGlobal(pos)"...

No, QObject has no mapToGlobal() but sender returns a (QObject -) pointer to your QDateEdit object so you can cast it as described in the documentation:
"Returns a pointer to the object that sent the signal, if called in a slot activated by a signal; otherwise it returns 0. The pointer is valid only during the execution of the slot that calls this function from this object's thread context."

@Christian-Ehrlicher ,
Thanks. I used below code:

QDateEdit* trh = qobject_cast<QDateEdit*>(sender());
QPoint globalPos = trh->mapToGlobal(pos);

Work like a charm.
