This libray consists of a group of classes which allow KDE
|
||
|
|
applications to access calendar dates outside of the limited range
|
||
|
|
of years imposed by QDate.
|
||
|
|
|
||
|
|
The QDate class has a limited range of valid dates. It does not
|
||
|
|
recognize dates prior to 14 Oct 1752 (when the Gregorian calendar
|
||
|
|
was adopted by England), nor dates after 31 Dec 8000. Both of these
|
||
|
|
limits are arbitrary.
|
||
|
|
|
||
|
|
|
||
|
|
The following classes are included:
|
||
|
|
|
||
|
|
ExtDate: Replaces QDate. There is no restriction on what dates
|
||
|
|
may be entered. For dates in the valid QDate range, it is
|
||
|
|
completely equivalent to QDate.
|
||
|
|
|
||
|
|
ExtDateTime: Replaces QDateTime. Consists of a QTime object
|
||
|
|
and an ExtDate object.
|
||
|
|
|
||
|
|
ExtCalendarSystem: Replaces KCalendarSystem. Uses ExtDate instead
|
||
|
|
of QDate. ExtCalendarSystem is a baseclass foundation for several
|
||
|
|
different calendar systems. A "calendar system" is just a method for
|
||
|
|
hierarchically subdividing the long count of days known as the Julian
|
||
|
|
Day Calendar into groups (weeks, months, years).
|
||
|
|
|
||
|
|
ExtCalendarSystemGregorian: Replaces KCalendarSystemGregorian.
|
||
|
|
The most common calendar system in modern western societies is the
|
||
|
|
Gregorian calendar. This class implements the Gregorian calendar
|
||
|
|
as a ExtCalendarSystem.
|
||
|
|
|
||
|
|
ExtDateTable: Replaces KDateTable.
|
||
|
|
ExtDatePicker: Replaces KDatePicker.
|
||
|
|
ExtDateTimeEdit: Replaces QDateTimeEdit.
|
||
|
|
ExtDateWidget: Replaces KDateWidget.
|
||
|
|
|
||
|
|
There are two test programs with the library, to verify the
|
||
|
|
functionality of the ExtDate classes:
|
||
|
|
|
||
|
|
test_extdate tests the non-GUI functionality, comparing results of
|
||
|
|
several operations with the results from QDate.
|
||
|
|
|
||
|
|
test_extdatepicker presents a KDatePicker widget and an ExtDatePicker
|
||
|
|
widget side-by-side.
