Reg->6.10: QKeySequence::isEmpty() changed semantics and/or Windows platform Quit key changed

XMLWordPrintable

    • Windows

      The code commonly used to achieve a common Ctrl-Q Quit shortcut (on Windows, where the standard key was empty in 6.9) no longer works in 6.10:

          auto ks = QKeySequence(QKeySequence::Quit);
    qDebug() << ks << "empty=" << ks.isEmpty();
    if (ks.isEmpty())
        ks = QKeySequence(Qt::CTRL | Qt::Key_Q);
    else
        qDebug() << "key=" << ks[0];
    auto *qa = fm->addAction("Quit", ks, &w, &QWidget::close);
    qDebug() << "act" << qa->shortcut();

      now produces

      6.10.0 windows windows11 QList()
QKeySequence("Exit")  empty= false
act QKeySequence("Exit")
key= QKeyCombination(QFlags<Qt::KeyboardModifier>(NoModifier), Qt::Key_Exit)
act QKeySequence("Exit")

      (not working) as opposed to 

      6.9.1 windows windows11 QList()
QKeySequence("")  empty= true
act QKeySequence("Ctrl+Q")
