+ *
+ * Since Calamares is supposed to work with Qt 5.9 or later, it covers a
+ * lot of changes in the Qt API. Especially the later Qt 5.15 (last LTS)
+ * versions deprecate a number of enum values and parts of the QWidgets
+ * API. This file adjusts for that by introducing suitable aliases
+ * and workaround-functions.
+ *
+ * For a similar approach for QtCore, see libcalamares/utils/String.h
