\class TQDateEdit ntqdatetimeedit.h
\brief The TQDateEdit class provides a date editor.
\ingroup advanced
\ingroup time
\mainclass
TQDateEdit allows the user to edit dates by using the keyboard or
the arrow keys to increase/decrease date values. The arrow keys
can be used to move from section to section within the TQDateEdit
box. Dates appear in accordance with the local date/time settings
or in year, month, day order if the system doesn't provide this
information. It is recommended that the TQDateEdit be initialised
with a date, e.g.
\code
TQDateEdit *dateEdit = new TQDateEdit( TQDate::currentDate(), this );
dateEdit->setRange( TQDate::currentDate().addDays( -365 ),
TQDate::currentDate().addDays( 365 ) );
dateEdit->setOrder( TQDateEdit::MDY );
dateEdit->setAutoAdvance( TRUE );
\endcode
Here we've created a new TQDateEdit object initialised with today's
date and restricted the valid date range to today plus or minus
365 days. We've set the order to month, day, year. If the auto
advance property is TRUE (as we've set it here) when the user
completes a section of the date, e.g. enters two digits for the
month, they are automatically taken to the next section.
The maximum and minimum values for a date value in the date editor
default to the maximum and minimum values for a TQDate. You can
change this by calling setMinValue(), setMaxValue() or setRange().
Terminology: A TQDateEdit widget comprises three 'sections', one
each for the year, month and day. You can change the separator
character using TQDateTimeEditor::setSeparator(), by default the
separator will be taken from the systems settings. If that is
not possible, it defaults to "-".

\class TQTimeEdit ntqdatetimeedit.h
\brief The TQTimeEdit class provides a time editor.
\ingroup advanced
\ingroup time
\mainclass
TQTimeEdit allows the user to edit times by using the keyboard or
the arrow keys to increase/decrease time values. The arrow keys
can be used to move from section to section within the TQTimeEdit
box. The user can automatically be moved to the next section once
they complete a section using setAutoAdvance(). Times appear in
hour, minute, second order. It is recommended that the TQTimeEdit
is initialised with a time, e.g.
\code
TQTime timeNow = TQTime::currentTime();
TQTimeEdit *timeEdit = new TQTimeEdit( timeNow, this );
timeEdit->setRange( timeNow, timeNow.addSecs( 60 * 60 ) );
\endcode
Here we've created a TQTimeEdit widget set to the current time.
We've also set the minimum value to the current time and the
maximum time to one hour from now.
The maximum and minimum values for a time value in the time editor
default to the maximum and minimum values for a TQTime. You can
change this by calling setMinValue(), setMaxValue() or setRange().
Terminology: A TQTimeWidget consists of three sections, one each
for the hour, minute and second. You can change the separator
character using setSeparator(), by default the separator is read
from the system's settings.

\class TQDateTimeEdit ntqdatetimeedit.h
\brief The TQDateTimeEdit class combines a TQDateEdit and TQTimeEdit
widget into a single widget for editing datetimes.
\ingroup advanced
\ingroup time
\mainclass
TQDateTimeEdit consists of a TQDateEdit and TQTimeEdit widget placed
side by side and offers the functionality of both. The user can
edit the date and time by using the keyboard or the arrow keys to
increase/decrease date or time values. The Tab key can be used to
move from section to section within the TQDateTimeEdit widget, and
the user can be moved automatically when they complete a section
using setAutoAdvance(). The datetime can be set with
setDateTime().
The date format is read from the system's locale settings. It is
set to year, month, day order if that is not possible. See
TQDateEdit::setOrder() to change this. Times appear in the order
hours, minutes, seconds using the 24 hour clock.
It is recommended that the TQDateTimeEdit is initialised with a
datetime, e.g.
\code
TQDateTimeEdit *dateTimeEdit = new TQDateTimeEdit( TQDateTime::currentDateTime(), this );
dateTimeEdit->dateEdit()->setRange( TQDateTime::currentDate(),
TQDateTime::currentDate().addDays( 7 ) );
\endcode
Here we've created a new TQDateTimeEdit set to the current date and
time, and set the date to have a minimum date of now and a maximum
date of a week from now.
Terminology: A TQDateEdit widget consists of three 'sections', one
each for the year, month and day. Similarly a TQTimeEdit consists
of three sections, one each for the hour, minute and second. The
character that separates each date section is specified with
setDateSeparator(); similarly setTimeSeparator() is used for the
time sections.
