-/**
- * THtmlArea class
- *
- * THtmlArea wraps the visual editting functionalities provided by the
- * TinyMCE project {@link http://tinymce.moxiecode.com/}.
- *
- * 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://tinymce.moxiecode.com/tinymce/docs/index.html
- * for a list of options. The options can be change/added as shown in the
- * following example.
- * <code>
- * <com:THtmlArea>
- * <prop:Options>
- * plugins : "contextmenu,paste"
- * language : "zh_cn"
- * </prop:Options>
- * </com:THtmlArea>
- * </code>
- *
- * Compatibility
- * The client-side visual editting capability is supported by
- * Internet Explorer 5.0+ for Windows and Gecko-based browser.
- * If the browser does not support the visual editting,
- * a traditional textarea will be displayed.
- *
- * Browser support

- * <code>
- * Windows XP MacOS X 10.4
