Once this extension is enabled in PHP it will provide the use of Newt widgets, such as windows, buttons, checkboxes, radiobuttons, labels, editboxes, scrolls, textareas, scales, etc. Use of this extension if very similar to the original Newt API of C programming language.
This module uses the functions of the RedHat Newt library. You need libnewt version >= 0.51.0.
Esta extension » PECL no esta ligada a PHP. Mas informacion sobre nuevos lanzamientos, descargas ficheros de fuentes, informacion sobre los responsables asi como un 'CHANGELOG', se puede encontrar aqui: » http://pecl.php.net/package/newt.
En PHP 4 la fuente de las extensiones PECL pueden encontrarse en el directorio ext/ que se existe en las fuentes de PHP o en el enlace PECL de arriba. In order to use these functions you must compile CGI or CLI PHP with newt support by using the --with-newt[=DIR] configure option.
Note: This extension is not available for Windows platform.
You may need also curses and slang libraries, in order to compile this extension. To specify locations of these libraries, use the following configuration options: --with-curses-dir=/path/to/libcurses --with-slang-dir=/path/to/libslang
This extension uses two resource types: "newt component" and "newt grid". Resource type "newt component" is returned by functions, which create common newt widgets (for example: newt_button()) Resource type "newt grid" is a special link identifier for components, returned by newt grid factory functions (for example: newt_create_grid())
Estas constantes están definidas por esta extensión y estarán disponibles solamente cuando la extensión ha sido o bien compilada dentro de PHP o grabada dinámicamente en tiempo de ejecución.
