/**
* Demonstrates all SWT DateTime widget modes and style combinations:
*
* DATE | MEDIUM - default date picker (MM/DD/YYYY)
* DATE | SHORT - compact date (MM/YYYY)
* DATE | LONG - same as MEDIUM (SWT doesn't add DOW on all platforms)
* DATE | DROP_DOWN - date field with inline calendar dropdown
* TIME | MEDIUM - time picker (HH:MM:SS)
* TIME | SHORT - compact time (HH:MM)
* CALENDAR - full month grid
* CALENDAR | CALENDAR_WEEKNUMBERS - calendar with ISO week numbers
*
* Also exercises: setDate(), setTime(), getDay/Month/Year/Hours/Minutes/Seconds
