NCFrame - NCurses C++ Framework

Motivation

NCFframe aims to facilitate NCurses based application development by providing a Qt inspired framework on top of NCurses. It provides common interfaces for widget construction and terminal events.

Example

Create a menu

NCFrame

#include <ncf/Application.hpp>
#include <ncf/Menu.hpp>

using namespace ncf;

int main(void)
{
  Application app;

  Menu menu {
    new Menu::Item {"Vim",    "A highly configurable text editor"},
    new Menu::Item {"Nano",   "The GNU Nano"},
    new Menu::Item {"Emacs",  "An extensible, customizable, free/libre text editor"},
    new Menu::Item {"Sublime","The text editor you'll fall in love with"},
    new Menu::Item {"Atom",   "A hackable editor for the 21st Century"},
    new Menu::Item {"Gedit",  "The GNOME text editor"}
  };

  menu.draw();

  app.start();

  return 0;
}
