wxWidgets Discussion Forum

Please don't tell me to ask developers, as it is just question not request
Why doesn't wx Have its own JDBC? Many app these days are DB driven but no official for wxWidgets. Is it inherited flaw from C++ itself?

I would like to hear your opinions

I think the main rationale is that wxWidgets is a GUI toolkit, not an all-encompassing framework. So it has to make choices and concentrate on where to spend its limited resources

Also, there are toolkits that specialize in DB-Access. So why would you roll your own, when it could never be of the same quality as the specialized?

would you point those ones for C++? I know JDBC for Java and MySQL Connector C++ but this one has no way to compile with my favorite MinGW. Not everybody wants to switch to MSVC

JDBC is Java's couterpart of ODBC in C. It's a generic, database independet API.

But there are C++ APIs too (don't know any, it's been some years since I looked. I rolled my own for DB2, because I wanted to use every trick to get the best performance out of DB2. No generic API for me, thanks). I remember one API, where the resultset is just another STL-Like-Container, very elegant. Don't remember it's name though...

Of course, first of all wxWidgets is a GUI toolkit, but minimal database support probably should be has, as well as it has XML support...

Mojo: if someone steps in and writes a great, solid, stable database layer for wx, and is ready to maintain it, I'm sure it will be welcome. Meanwhile, wx does not have enough developers for that

Sure I would make it with pleasure, but I'm afraid I don't have enough experience in database field hope in someday I'll get it and write a great, solid, stable database layer for wx.

There is the wxCode component DatabaseLayer developed by Joseph Blough providing a JDBC-like interface and supporting several database systems (i.e. FireBird, MySQL, ODBC, Oracle, OTL, Postgres, SQLite, and TDS).

I think of DatabaseLayer as a definition how to adapt database systems to wxWidgets. I think about using interfaces (pure abstract classes) instead of a layer between wxWidgets and database backends. But then you are responsible to do much more than writing the backend.

I would argue that DatabaseLayer IS the one to be used for wxWidgets based applications. The library has a stable interface - in my view - as there are many backends, and thus it would be my choice if I write a plain wxWidgets database app.
