/**
 * TTextBox class
 *
 * TTextBox displays a text box on the Web page for user input.
 * The text displayed in the TTextBox control is determined by the
 * {@link setText Text} property. You can create a <b>SingleLine</b>,
 * a <b>MultiLine</b>, or a <b>Password</b> text box by setting
 * the {@link setTextMode TextMode} property. If the TTextBox control
 * is a multiline text box, the number of rows it displays is determined
 * by the {@link setRows Rows} property, and the {@link setWrap Wrap} property
 * can be used to determine whether to wrap the text in the component.
 *
 * To specify the display width of the text box, in characters, set
 * the {@link setColumns Columns} property. To prevent the text displayed
 * in the component from being modified, set the {@link setReadOnly ReadOnly}
 * property to true. If you want to limit the user input to a specified number
 * of characters, set the {@link setMaxLength MaxLength} property.
 * To use AutoComplete feature, set the {@link setAutoCompleteType AutoCompleteType} property.
 *
 * If {@link setAutoPostBack AutoPostBack} is set true, updating the text box
 * and then changing the focus out of it will cause postback action.
 * And if {@link setCausesValidation CausesValidation} is true, validation will
 * also be processed, which can be further restricted within
 * a {@link setValidationGroup ValidationGroup}.
