- Remove class DragLabel in draggabletext and add a static creation function instead since it only has a constructor setting some properties. - Use QRegularExpression instead of QRegExp - Use new connection syntax. - Ensure compilation with DEFINES += QT_NO_CAST_TO_ASCII QT_NO_CAST_FROM_ASCII demonstrating use of QLatin1String vs QStringLiteral. - Streamline code.
