+ \class Q3DateEdit
+ \brief The Q3DateEdit class provides a date editor.
+
+ \compat
+
+ Q3DateEdit 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 Q3DateEdit
+ 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 Q3DateEdit be initialised
+ with a date, e.g.
+
+ \snippet doc/src/snippets/code/src_qt3support_widgets_q3datetimeedit.cpp 0
+
+ Here we've created a new Q3DateEdit 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 QDate. You can
+ change this by calling setMinValue(), setMaxValue() or setRange().
+
+ Terminology: A Q3DateEdit widget comprises three 'sections', one
+ each for the year, month and day. You can change the separator
+ character using Q3DateTimeEditor::setSeparator(), by default the
+ separator will be taken from the systems settings. If that is
+ not possible, it defaults to "-".

+ \class Q3TimeEdit
+ \brief The Q3TimeEdit class provides a time editor.
+
+ \compat
+
+ Q3TimeEdit 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 Q3TimeEdit
+ 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 Q3TimeEdit
+ is initialised with a time, e.g.
+ \snippet doc/src/snippets/code/src_qt3support_widgets_q3datetimeedit.cpp 1
+ Here we've created a Q3TimeEdit 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 QTime. You can
+ change this by calling setMinValue(), setMaxValue() or setRange().
+
+ Terminology: A QTimeWidget 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 Q3DateTimeEdit
+ \brief The Q3DateTimeEdit class combines a Q3DateEdit and Q3TimeEdit
+ widget into a single widget for editing datetimes.
+
+ \compat
+
+ Q3DateTimeEdit consists of a Q3DateEdit and Q3TimeEdit 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 Q3DateTimeEdit 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
+ Q3DateEdit::setOrder() to change this. Times appear in the order
+ hours, minutes, seconds using the 24 hour clock.
+
+ It is recommended that the Q3DateTimeEdit is initialised with a
+ datetime, e.g.
+ \snippet doc/src/snippets/code/src_qt3support_widgets_q3datetimeedit.cpp 2
+ Here we've created a new Q3DateTimeEdit 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 Q3DateEdit widget consists of three 'sections', one
+ each for the year, month and day. Similarly a Q3TimeEdit 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.
