Re: [wxhaskell-users] TableBase

[Michael J. <mi...@pr...>]

From my review, I think I would have to create a subclass of wxGridTableBase in C++, wrapper it in C wrapper, then wrapper C in Haskell. And to be general purpose, the subclass would have to make calls into Haskell with some way to register a function, like the way events work in wxHaskell.

Correct me if there is something I am missing.

And if I create this subclass, which is not part of wxWidgets source, where would it reside in wxHaskell source tree? I believe wxc is generated by wxdirect. Would it go in the wxcore tree as a subdir of UI/WxCore?

There is, however, a C++ sample program (griddemo) included in the wxWidgets source. WxHaskell is a huge library and much of it is uncharted territory, you will probably be the first to use GridTableBase in a Haskell program. It would be great if you could add a sample program to wxHaskell.
