   A date editing widget that consists of an editable combo box.
   The combo box contains the date in text form, and clicking the combo
   box arrow will display a 'popup' style date picker.
 
   This widget also supports advanced features like allowing the user
   to type in the day name to get the date. The following keywords
   are supported (in the native language): tomorrow, yesterday, today,
   monday, tuesday, wednesday, thursday, friday, saturday, sunday.
