I complately agree. That was also an unspoken point of my posting - that there's an enourmous amount of work to do this. Just wrapping/emulating _one_ platform is a lot of work. I've been working on a Windows/Direct3D wrapper, myself, which wraps the Win32 API, and especially due to the low-level nature of this API, it's a lot of work to do so. Since I discovered wxWindows, I've preferred to use that, instead, than duplicating all the work that has gone into cross-platform GUI toolkits/frameworks like wxWindows. > I am certainly not against the OP trying to do something like this for Boost > but I think that is naive to assume that one can create such a Boost > templated cross-platform framework without a tremendous amount of work and > time spent invesigating the GUI and graphics APIs of a number of OSs.

That has also been my thought. As we've both pointed out, greating such a library is a lot of work. There's a reason there's not yet a Boost.GUI. There's a lot of developers at the wxWindows project, for example, showing this. I just wanted to point out this point, too, to consider existing libraries, as well. Boost has several times adopted libraries originating elsewhere, and with an existing body of developers, as well, e.g. Boost.Spirit. The other mentioned cross-platform GUI similar in capability to wxWindows, Qt, is not Open Source - there's an older Open Source non-commercial Windows version, but not the more recent one, and not for commercial use. That makes its license incompatible with Boost. Regards, Terje _______________________________________________ Unsubscribe & other changes: http://lists.boost.org/mailman/listinfo.cgi/boost
