why doesnt the C++ standard library committee offer any AUI related libararie?

hello all, its been a while that i am thinking why the committee that releases the standard C++ libraries ( header files , stuff) doesnt offer any library fo AUI , i know there are couple of GUI frameworks for C++ out there , but why dont they do it themselves!
by doing such a thing C++ standard library would cover much more stuff and thus the need to use third party frameworks and thus solving problems associated with them would vanish!

whats your idea?

Stroustrup does give an answer concerning a standard GUI: Why doesn't C++ have a GUI? Admittedly, it sounds a little like he is avoiding the question but reluctantly putting it on his FAQ because it really is frequently asked.

It would be extremely hard to standardize a GUI; they aren't standardized across operating systems, so trying to standardize it in the CORE of a programming language would be a horrible idea. Visual Basic is the only language I know of that actually did a good job with doing that (On the flip side, it was bad at almost everything else... and only worked on windows)

thanks, i get it now.
