Answer 1

You can use the more appropriate syntax according to Qt version:

#if QT_VERSION >= 0x050000
    connect(item, &QListWidget::itemChanged, this , &MainWindow::checkItemChanged);
#else
    connect(item, SIGNAL(checkItemChanged), this , SLOT(checkItemChanged));
#endif

(or the 'old string-based' for all versions).
