Qt is a wonderful GUI toolkit, but new language bindings are notoriously difficult, since it depends not only on C++ (which itself is tricky to bind into other languages) but also the Qt meta-object compiler. Even so, some interesting projects have emerged on that front. For example:
This (header-only) library can be used to create an application using Qt, without the need of the moc (MetaObject Compiler). It uses a different set of macro than Qt and templated constexpr code to generate the QMetaObject at compile-time. It is entirely binary compatible with Qt.
DQt:
DQt contains experimental bindings for using a subset of Qt with the D Programming Language. Qt is a library for writing cross-platform graphical user interfaces. Currently bindings exist for the Qt modules core, gui, widgets and webenginewidgets.
How would you have to modify the process to make liquid soap, like Dr Bronners, and skip the molds?
