| /** |
| * Instances of this class are selectable user interface |
| * objects that allow the user to enter and modify text. |
| * Text controls can be either single or multi-line. |
| * When a text control is created with a border, the |
| * operating system includes a platform specific inset |
| * around the contents of the control. When created |
| * without a border, an effort is made to remove the |
| * inset such that the preferred size of the control |
| * is the same size as the contents. |
| * <p> |
| * <dl> |
| * <dt><b>Styles:</b></dt> |
| * <dd>CENTER, ICON_CANCEL, ICON_SEARCH, LEFT, MULTI, PASSWORD, SEARCH, SINGLE, RIGHT, READ_ONLY, WRAP</dd> |
| * <dt><b>Events:</b></dt> |
| * <dd>DefaultSelection, Modify, Verify, OrientationChange</dd> |
| * </dl> |
| * <p> |
| * Note: Only one of the styles MULTI and SINGLE may be specified, |
| * and only one of the styles LEFT, CENTER, and RIGHT may be specified. |
| * </p> |
| * <p> |
| * Note: The styles ICON_CANCEL and ICON_SEARCH are hints used in combination with SEARCH. |
| * When the platform supports the hint, the text control shows these icons. When an icon |
| * is selected, a default selection event is sent with the detail field set to one of |
| * ICON_CANCEL or ICON_SEARCH. Normally, application code does not need to check the |
| * detail. In the case of ICON_CANCEL, the text is cleared before the default selection |
| * event is sent causing the application to search for an empty string. |
| * </p> |
| * <p> |
| * IMPORTANT: This class is <em>not</em> intended to be subclassed. |
