Hi all,

first of all, I'm new to D.
I work as software Td for a VFX company, therefore I work a lot with OpenGL. D can interface with OpenGL without problems, but most of the time I also need a very solid library to develop a GUI, and in my industry Qt is now the adopted standard.

D is too young to be adopted in the (crazy) VFX industry, but I really like the language and I would like to do some basic stuff with it on my spare time.

I just wanted to ask you guys how fast is Qtd compare to the pure c++ Qt. Are the overheads really sensible? And how is the wrapper itself, is it solid, does it perform well?
Please be completely honest on your answer, I just want to hear your opinion based on practical experience

Thank you very much guys,
Dan

Hi Dan,

Sorry for the delayed reply.

QtD is too immature to be used in a production environment. Sorting out all the issues will take a while.

It promises too be fairly fast. The main source of overhead is non-polymorphic by-ref objects (and polymorphic non-QObjects created by Qt). Marshalling such an object to D requires either creating a new wrapper or searching a per-class cache.

Qt value types will be wrapped in D structs so the overhead for those will be minimal.

Details are still being worked out.
