Hi,
I've been working on a GUI library named Nana, it's a pure C++ library based on C++11. Now I am great interested in sending the library to C++ standard library.

Nana C++ Library takes aim at easy-to-use and portable GUI library, but the most important feature is to provide a modern C++ style for GUI programming, it conforms to the C++11 standard, use these great C++11 features to get clean, safe, and fast code.

//Go through the each item in listbox category 0.
for(auto & m : listbox.at(0)) {
    //...each item...
}

//Use lambda
button.make_event<events::click>([](){
    //handle the event, leave out the event argument.
});

//C++14
button.make_event<events::click>([](auto & evt_arg)
{
    int x = evt_arg.mouse.x; //get the cursor position when clicking.
});

Key features:
* Unicode support
    Bidirectional display order, the correct of display of text containing both left-to-right and right-to-left script.
* Character Set Conversion
    Facilities for conversion between locale character set and Unicode character set with Unicode Transform Format.
* Graphics System.
    Nana provides a stand-alone graphics system as a basis of GUI system, but this module will be replaced by the 2D graphics which is a proposal described in paper N4073.
* Abstract API
    It defines a set of platform-independent interfaces to manipulate a window.
* Image Processing Algorithm Framework
* Widget Classes
* Layout Management
* Thread-safe.

GUI library is a complicated project, but the project will keep evolving for C++.
Some links to the project.

All feedbacks are welcome.
Best regards
Jinhao

<![endif]--><br>Nana C++ Library takes aim at easy-to-use and portable GUI =
library, but the most important feature is to provide a modern C++ style fo=
r GUI programming, it conforms to the C++11 standard, use these great C++11=
 features to get clean, safe, and fast code.<br><br>//Go through the each i=
tem in listbox category 0.<br>for(auto &amp; m : listbox.at(0)) {<br>&nbsp;=

 Facilities for conversion between locale character set and Unicode charact=
er set with Unicode Transform Format.<br>* Graphics System.<br>&nbsp;&nbsp;=
&nbsp; Nana provides a stand-alone graphics system as a basis of GUI system=
, but this module will be replaced by the 2D graphics which is a proposal d=
escribed in paper N4073.<br>* Abstract API<br>&nbsp;&nbsp;&nbsp; It defines=
 a set of platform-independent interfaces to manipulate a window.<br>* Imag=
e Processing Algorithm Framework<br>* Widget Classes<br>* Layout Management=
<br>* Thread-safe.<br><br>GUI library is a complicated project, but the pro=
ject will keep evolving for C++.<br>Some links to the project.<br>http://ww=
