Hi Wolfgang,
I was wondering if I can use FLTK as GUI backend for Grapefruit?
This should be possible in principal. It just could be that my assumptions
about how widgets are created and composed were too tight so that
Grapefruit’s general interface doesn’t fit FLTK. In this case, please just
tell me and I will try to make the interface more general.
Ok, great I ll have to use them then I will see and know what improvement
is needed.
I believe for this to make it happen, I would have to output FLTK's C++
into C then create bindings for Haskell (via FFI). Is that doable or an
quite tall order?
Recently, a student of mine has written a program which generates a Haskell Qt
binding fully automatically from Qt header files. The generated binding
consists of three layers. The first layer is C++ code which reexports Qt’s
functionality as a pure C interface. The C interface is ugly for humans and
not type safe (because C doesn’t know classes). The second layer consists of
a couple of FFI declarations. The third layer is Haskell code which provides
a nice interface similar to the original C++ interface.
I still have to get the source code of the binding generator from that student
but I hope this will happen soon. I want to publish it then on the web. It
hope that it is possible to reuse this binding generator for other C++
libraries.
That would be very helpful, I ll be looking forward.
Best wishes,
Wolfgang
