+ * @short A date selection widget.
+ *
+ * Provides a widget for calendar date input.
+ *
+ *     Different from the
+ *     previous versions, it now emits two types of signals, either
+ * dateSelected() or dateEntered() (see documentation for both
+ *     signals).
+ *
+ *     A line edit has been added in the newer versions to allow the user
+ *     to select a date directly by entering numbers like 19990101
+ *     or 990101.
