Following the migration to QT5, few bugs need to be fixed:

space does not close the creation mode (while it should be)
same for translation/rotation/scale mode (space should close the operation)
multi-view is broken (shortcut 4)

Hello Guillaume,

Regarding file loading problems between OS, one of the potential culprits would be the use of non-compiler portable data types. When saving the darts, I saw several casts in types which have different sizes depending on the platform.
In particular from long int to int, a snippet is worth a thousand words: link to godbolt

I would recommend using portable sized-integer types (uint32_t, uintptr_t, etc...) from <cstdint> or <stdint.h> (according to your preference) during saving and loading operations (in files like gmv-save.cc, streams.icc, dart-vertex.icc in lib-gmapkernel).

I don't know the size and scope of such a change in the code base. We had made some ad hoc modifications to a code base for a particular need in Poitiers, but nothing clean enough to make it an effective pull-request yet.

This issues can serve as a reminder for the time being. I'm preparing another pull-request for you regarding the Moka CMakeLists.txt for the compilation on Windows.
