| 146 | |
| 147 =head2 BLOCKS | |
| 148 | |
| 149 =head3 INIT | |
| 150 | |
| 213 | 151 Данный блок шаблона управления выполняется один раз при создании первого экземпляра элемента управления, |
| 152 может использоваться для формирования заголовочной части документа, скрипта подключающего ajax модули | |
| 153 при необходимости и т.п. | |
| 181 | 154 |
| 155 =head3 CTOR | |
| 156 | |
| 157 данный блок выполняется каждый раз при создании нового экземпляра элемента управления, при этом переменная C<this> | |
| 213 | 158 указывает на эземпляр элемента упарвления. Данный блок можно использовать для инициализации свойств элемента |
| 159 управления. | |
| 181 | 160 |
| 161 =head3 RENDER | |
| 162 | |
| 213 | 163 Данный блок выполняется при вызове метода C<Render()>, вывод данного блока и есть результат отображения элемента управления. |
| 164 Если в шаблоне нет блока C<RENDER>, то сам шаблон считается таковым. | |
| 187 | 165 |
| 166 =head2 TEMPLATE VARS | |
| 167 | |
| 168 Каждый шаблон имеет собственное пространство имен, унаследованное от пространства имен фабрики элементов (которая в свою очередь наследует контекст документа). | |
| 169 В шаблоне могут определяться новые переменные, которые разделяются между блоками. Также доступны стандартные переменные | |
| 170 | |
| 171 =over | |
| 172 | |
| 173 =item * C<this> ссылка на объект элемента управления | |
| 174 | |
| 175 =item * C<component> ссылка на текущий шаблон, устанавливается автоматически в методе C<Template::Context::process>. | |
| 176 | |
| 177 =item * C<template> ссылка на шаблон элемента управления, для совместимости с C<TT> | |
| 178 | |

| 182 | |
| 183 =over | |
| 184 | |
| 185 =item * C<[get]context> | |
| 186 | |
| 187 Контекст элемента управления, хранит пременные шаблона. Наследуется от контекста фабрики элементов управления, который | |
| 188 наследуется от контекста документа. | |
| 189 | |
| 190 =item * C<[get,set]template> | |
| 191 | |
| 192 C<Template::Document> Шаблон элемента управления. | |
| 193 | |
| 194 =item * C<AUTOLOAD> | |
| 195 | |
| 196 Для удобства работы с шаблоном, элементы управления предоставляю доступ к своим свойствам через метод C<AUTOLOAD>. | |
