+* A date editing widget that consists of a line edit followed by
+* a small push button. The line edit contains the date in text form,
+* and the push button 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, yesturday, today,
+* monday, tuesday, wednesday, thursday, friday, saturday, sunday.
