* render selection focus. When both text and image is enclosed, selection and
 * rendering will affect both as a single hyperlink.
 * </p>
 * <p>
 * Since 3.1, it is possible to select text. Text selection can be
 * programmatically accessed and also copied to clipboard. Non-textual objects
 * (images, controls etc.) in the selection range are ignored.
 * <p>
 * Care should be taken when using this control. Form text is not an HTML
 * browser and should not be treated as such. If you need complex formatting
 * capabilities, use Browser widget. If you need editing capabilities and
 * font/color styles of text segments is all you need, use StyleText widget.
 * Finally, if all you need is to wrap text, use SWT Label widget and create it
 * with SWT.WRAP style.

 * @see FormToolkit
 * @see TableWrapLayout
 * @since 3.0
