Nana (C++ library)

Nana is a cross-platform C++ library for creating graphical user interfaces. It uses a platform-independent API and currently supports Windows, Linux^[1] and FreeBSD.^[2]

Nana is free and open-source software, licensed under the Boost Software License.

Architecture and design[]

Nana is an object-oriented widget toolkit using generic programming^[3] and written in Standard C++. It can therefore be compiled by any Standard C++ compiler (VC2013, GCC/MinGW, Clang).

The primary design goal of Nana is to make things simple and intuitive to C++ developers: it therefore uses many advanced C++ features, such as templates, standard libraries, exception and RTTI. It fully supports C++11 since 2012,^[4] giving the developers the freedom to use various modern C++ features such as lambda functions, smart pointers and the standard library.

Language bindings[]

Nana was written in C++ and targets only this language.

The following Nana example^[5] creates a window with a "Hello, World" caption and a "Quit" button:

#include <nana/gui/wvl.hpp>
#include <nana/gui/widgets/button.hpp>

int main()
{
     using namespace nana;
     form fm;                   // The form is a window with title bar and a sizable border frame, 
     fm.caption("Hello World");
     button btn(fm, rectangle(20, 20, 150, 30));
     btn.caption("Quit");
     btn.events().click(API::exit);  // API::exit is a function that is triggered on click
     fm.show();
     exec();
}
