Qt 6 support (#2069) * Bump minimum Qt version to 5.6 * Switch from QRegExp to QRegularExpression While still available, QRegExp has been moved to Qt6::Core5Compat module and is not part of Qt6::Core. * Use qIsEffectiveTLD instead of QUrl::topLevelDomain The latter is not part of Qt6::Core. The former is a private utility in Qt6::Network; using it for now, until (and if) we switch to something non-Qt-specific. * Use QStyle::State_Horizontal state when drawing progress bars Although available for a long time, this state either didn't apply to progress bars before Qt 6, or was deduced based on bar size. With Qt 6, failing to specify it results in bad rendering. * Don't use QStringRef (and associated methods) While still available, QStringRef has been moved to Qt6::Core5Compat module and is not part of Qt6::Core. Related method (e.g. QString::midRef) have been removed in Qt 6. * Use Qt::ItemIsAutoTristate instead of Qt::ItemIsTristate The latter was deprecated and replaced with the former in Qt 5.6. * Don't use QApplication::globalStrut This property has been deprecated in Qt 5.15 and removed in Qt 6. * Use QImage::fromHICON instead of QtWin::fromHICON WinExtras module (providind the latter helper) has been removed in Qt 6. * Use QStringDecoder instead of QTextCodec While still available, QTextCodec has been moved to Qt6::Core5Compat module and is not part of Qt6::Core. * Don't forward-declare QStringList Instead of being a standalone class, its definition has changed to QList<QString> template specialization in Qt 6. * Use explicit (since Qt 6) QFileInfo constructor * Use QDateTime's {to,from}SecsSinceEpoch instead of {to,from}Time_t The latter was deprecated in Qt 5.8 and removed in Qt 6. * Don't use QFuture<>'s operator== It has been removed in Qt 6. Since the original issue this code was solving was caused by future reuse, just don't reuse futures and create new finished ones when necessary. * Use std::vector<> instead of QVector<> The latter has been changed to a typedef for QList<>, which might not be what one wants, and which also changed behavior a bit leading to compilation errors. * Don't use + for flags, cast to int explicitly Operator+ for enum values has been deleted in Qt 6, so using operator| instead. Then, there's no conversion from QFlags<> to QVariant, so need to cast to int. * Support Qt 6 in CMake and for MSI packaging * Remove extra (empty) CMake variable use when constructing Qt target names * Simplify logic in tr_qt_add_translation CMake helper Co-authored-by: Charles Kerr <charles@charleskerr.com>
