This is a PHP language extension for RedHat Newt library, a terminal-based window and widget library for writing applications with user friendly interface. 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.
Это расширение » PECL не поставляется вместе с PHP. Дополнительная информация, такая как новый версии, скачивание, исходные файлы, информация о разработчике и CHANGELOG, могут быть найдены здесь: » http://pecl.php.net/package/newt.
В PHP 4 исходные файлы этого расширения PECL могут быть найдены в директории ext/ внутри исходных файлов PHP или по ссылке PECL выше. 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())
Перечисленные ниже константы определены данным расширением и могут быть доступны только в том случае, если PHP был собран с поддержкой этого расширения или же в том случае, если данное расширение подгружается во время выполнения.
