C++ Question

What is the downside of having a standard GUI library for C++?

For GUI programming in C++, we can choose between too many libraries, such as Qt, Gtkmm, wxWidgets, FLTK and there is another one which already exists: Nana.

Nana C++ library is using modern C++ (C++11) language features such as lambdas, templates and more, and it seems to be compatible with C++ standard library.

If a GUI library is 100% compatible with C++ standard library, then why cannot we have it for next C++ standard (C++14 or C++17)?

Which conditions are necessary for a library to be in C++ standard library? if conditions are not defined, then we are doomed forever to be in a black hole of text and it will hurt your heart! Otherwise if conditions are defined, then where can i request a library to be within the next C++ standard?

Answer

Bjarne Stroustrup has already answered this question:

Why doesn't C++ have a GUI?

C++ has many commercial and open source GUIs (e.g. Gtkmm, SmartWin++, V C++ GUI, FLTK, and Qt). In particular, every platform vendor provides a C++ library to access their GUI. The problem is that it doesn't have a standard GUI, and that is indeed a major problem. Note that providing a GUI is both a technical and political problem. There are lots of GUIs with lots of users, and generally they wouldn't like some other GUI to be declared standard. Anyway, the standards committee do not have the resources to build a new and better GUI.
