/**
 * THtmlArea5 class
 *
 * THtmlArea5 wraps the visual editing functionalities provided by the
 * version 5 of TinyMCE project {@link http://tinymce.com/}. It has been
 * developed as a plug'n'play substitute for {@link THtmlArea}, that is
 * based on a previous iteration (version 3) of the same project.
 * Please note that both components can't be used together in the same page.
 *
 * THtmlArea displays a WYSIWYG text area on the Web page for user input
 * in the HTML format. The text displayed in the THtmlArea component is
 * specified or determined by using the <b>Text</b> property.
 *
 * To enable the visual editting on the client side, set the property
 * <b>EnableVisualEdit</b> to true (which is default value).
 * To set the size of the editor when the visual editting is enabled,
 * set the <b>Width</b> and <b>Height</b> properties instead of
 * <b>Columns</b> and <b>Rows</b> because the latter has no meaning
 * under the situation.
 *
 * The default editor gives only the basic tool bar. To change or add
 * additional tool bars, use the {@link setOptions Options} property to add additional
 * editor options with each options on a new line.
 * See http://www.tinymce.com/wiki.php/Configuration
 * for a list of options. The options can be change/added as shown in the
 * following example.
 * <code>
 * <com:THtmlArea5>
 *       <prop:Options>
 *         language : "de"
 *         plugins: "advlist anchor autolink autoresize autosave charmap code directionality emoticons fullscreen hr image importcss insertdatetime link lists media nonbreaking noneditable pagebreak paste preview print save searchreplace tabfocus table template visualblocks visualchars wordcount"
 *         toolbar: "undo redo | styleselect | bold italic | alignleft aligncenter alignright alignjustify | bullist numlist outdent indent | link image     | print preview media",
 *         statusbar: false
 *      </prop:Options>
 * </com:THtmlArea5>
 * </code>
