42 | * Provides a widget for calendar date input. |
43 | * |
44 | * Different from the |

46 | * dateSelected() or dateEntered() (see documentation for both |
47 | * signals). |
48 | * |
49 | * A line edit has been added in the newer versions to allow the user |
50 | * to select a date directly by entering numbers like 19990101 |
51 | * or 990101. |
