 * All widgets placed in the cell have some values in common:

 *                                     for example a text_box can get the proper
 *                                     initial value. This value should be
 *                                     unique or empty. Those special values are
 *                                     documented at the window definition that

 *                                     specific version of the widget e.g. a
 *                                     title label when the label is used as

 *                                     at the widget. E.g. an image uses the

 *                                     message should show more help. This
 *                                     defines the text of that message. $
