+ \class ExtDateEdit ExtDatetimeedit.h
+ \brief The ExtDateEdit class provides a date editor.
+
+ \ingroup advanced
+ \ingroup time
+
+ ExtDateEdit 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 ExtDateEdit
+ 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 ExtDateEdit be initialised
+ with a date, e.g.
+
+ \code
+ ExtDateEdit *dateEdit = new ExtDateEdit( ExtDate::tqcurrentDate(), this );
+ dateEdit->setRange( ExtDate::tqcurrentDate().addDays( -365 ),
+ ExtDate::tqcurrentDate().addDays( 365 ) );
+ dateEdit->setOrder( ExtDateEdit::MDY );
+ dateEdit->setAutoAdvance( TRUE );
+ \endcode
+
+ Here we've created a new ExtDateEdit 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 ExtDate. You can
+ change this by calling setMinValue(), setMaxValue() or setRange().
+
+ Terminology: A ExtDateEdit widget comprises three 'sections', one
+ each for the year, month and day. You can change the separator
+ character using ExtDateTimeEditor::setSeparator(), by default the
+ separator will be taken from the systems settings. If that is
+ not possible, it defaults to "-".

+ 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.

+
+ ExtDateTimeEdit consists of a ExtDateEdit 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 ExtDateTimeEdit 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
+ ExtDateEdit::setOrder() to change this. Times appear in the order
+ hours, minutes, seconds using the 24 hour clock.
+
+ It is recommended that the ExtDateTimeEdit is initialised with a
+ datetime, e.g.
+ \code
+ ExtDateTimeEdit *dateTimeEdit = new ExtDateTimeEdit( ExtDateTime::tqcurrentDateTime(), this );
+ dateTimeEdit->dateEdit()->setRange( ExtDateTime::tqcurrentDate(),
+ ExtDateTime::tqcurrentDate().addDays( 7 ) );
+ \endcode
+ Here we've created a new ExtDateTimeEdit 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 ExtDateEdit 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.
