Hi!
Calypso just got a D translation of the first Qt5 Widgets
tutorial building and running:
https://github.com/Syniurge/Calypso/blob/master/tests/calypso/qt5/qt5demo.d
Result: http://homo-nebulus.fr/dlang/oh%20my.webm
Compilation log: https://paste.kde.org/pewbbsw45
Previously Calypso was merely able to work with STL types, this
is the first time a large C++ library is successfully mapped and
used by D code (Ogre3D is probably close as well, but after
Kagamin's suggestion and for a change of scene I switched my
focus from Ogre3D to Qt).
