Nana library is written though standard C++, this is a big difference between other
libraries, as the brief mentioned, C++ idioms should works with a C++ library, and
this is why the other popular GUI C++ libraries are not really C++ style at all.
Secondly, this library can be work with a thread pool, it reduces the difficulty
for threadization.

I recognize that many ideas of my own solutions come from boost, not only

boost.thread, there are boost.function, boost.any and so on, this is why I

try to submit this library to boost and erase all my own solutions.

Somebody told me the problem before, I left the problem and searched a solution,
I found many problem can be fixed by boost, and I rethink, can't keep on stealing
ideas from boost. This is also why I try to submit this library to boost.

Target platforms should be Windows, Linux and Mac OS X, but now, it only works under
Windows(GDI) and Linux(X11), the next is ready for Linux(framebuffer). A friend of
mine asks for the support of framebuffer, so I leave the Mac OS X now.

Yes, like ncurses. But now it is not able to work in such environment.

The library provide a general method to implement a customer widget, and supports
external image-processing algorithm implementation

Yes, but its language is Chinese, it is a stock software, a screenshot at
http://sourceforge.net/projects/stdex
The status of this library I give is alpha and the so library is not used widely.
