How can I capture QKeySequence from QKeyEvent depending on current keyboard layout?

Question

I need to do this for configuring my application. I have QLineEdit field with reimplemented keyPressEvent method.

QKeyEvent *ke = ...
QString txt;

if(ke->

What you might find very useful is the function QKeySequence().toString().

The following is a part of a code that I use to capture User Defined Shortcuts. With some modifications it can do whatever you need in your project. Hope it helps (sorry for the crapped identation):

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

    int keyInt = keyEvent->key(); 
    Qt::Key key = static_cast(keyInt); 
    if(key == Qt::Key_unknown){ 
        qDebug() << "Unknown key from a macro probably"; 
        return; 
    } 
    // the user have clicked just and only the special keys Ctrl, Shift, Alt, Meta. 
    if(key == Qt::Key_Control || 
        key == Qt::Key_Shift || 
        key == Qt::Key_Alt || 
        key == Qt::Key_Meta)
    { 
        qDebug() << "Single click of special key: Ctrl, Shift, Alt or Meta"; 
        qDebug() << "New KeySequence:" << QKeySequence(keyInt).toString(QKeySequence::NativeText); 
        return; 
    } 

    // check for a combination of user clicks 
    Qt::KeyboardModifiers modifiers = keyEvent->modifiers(); 
    QString keyText = keyEvent->text(); 
    // if the keyText is empty than it's a special key like F1, F5, ... 
    qDebug() << "Pressed Key:" << keyText; 

    QList modifiersList; 
    if(modifiers & Qt::ShiftModifier) 
        keyInt += Qt::SHIFT; 
    if(modifiers & Qt::ControlModifier) 
        keyInt += Qt::CTRL; 
    if(modifiers & Qt::AltModifier) 
        keyInt += Qt::ALT; 
    if(modifiers & Qt::MetaModifier) 
        keyInt += Qt::META; 

    qDebug() << "New KeySequence:" << QKeySequence(keyInt).toString(QKeySequence::NativeText); 
}
