QEvent::KeyPress for Enter and Return, Detection Qt::Modifiers on Enter doesn't work

[HappyCoder]

Hello,

i have a eventFilter where i catch a presses Key like this:

if ( event->type() == QEvent::KeyPress)
    {
        QKeyEvent *keyEvent = static_cast<QKeyEvent*>(event);
 
        switch ( keyEvent->key() )
        {
        case Qt::Key_Enter:
            qDebug() << "Enter";
        case Qt::Key_Return:
        {
            qDebug() << "Return";
            if( keyEvent->modifiers()==Qt::NoModifier )
            {
                qDebug() << "NoModifier";
            }
            if( keyEvent->modifiers()==Qt::ShiftModifier )
            {
                qDebug() << "ShiftModifier";
            }
            break;
        }
        case Qt::Key_Escape:
            qDebug() << "Escape"
        default:
            break;
        }
    }

if ( event->type() == QEvent::KeyPress)
    {
        QKeyEvent *keyEvent = static_cast<QKeyEvent*>(event);

        switch ( keyEvent->key() )
        {
        case Qt::Key_Enter:
            qDebug() << "Enter";
        case Qt::Key_Return:
        {
            qDebug() << "Return";
            if( keyEvent->modifiers()==Qt::NoModifier )
            {
                qDebug() << "NoModifier";
            }
            if( keyEvent->modifiers()==Qt::ShiftModifier )
            {
                qDebug() << "ShiftModifier";
            }
            break;
        }
        case Qt::Key_Escape:
            qDebug() << "Escape"
        default:
            break;
        }
    }

To copy to clipboard, switch view to plain text mode 

when I press "Return", everything is OK i get as output

Return
NoModifier or ShiftModifier

but when I press "Enter" the detection of the modifiers doesn't work. The output is always

Enter
Return
(no output of "NoModifier" or "ShiftModifier")

What I'm doing wrong?

Thx
Stefan
