Hello! How to make connect with different arguments (qint64 and int)?

connect(player, SIGNAL(positionChanged(qint64)), ui->clock, SLOT(display(int)));

player - QMediaPlayer || clock - QLCDNumber

    Try this (qt5 syntax). The idea should be given automatically

     QObject::connect(player, &QMediaPlayer::positionChanged, ui->clock, &QLCDNumber::display);

    EDIT

    Unfortunately, QLCDNumber has several display (int, double) slots. Which compiler to use is unclear and it needs to be explicitly stated to it:

     QObject::connect(player, &QMediaPlayer::positionChanged, ui->clock, static_cast<void(QLCDNumber::*)(int)>(&QLCDNumber::display));

    Or use lambda

     QObject::connect(player, &QMediaPlayer::positionChanged, this, [this](qint64 _arg) { ui->clock->display(static_cast<int>(_arg)); });

    Any of this should work =)
