38 | \class QDateTimeEdit |
39 | \brief The QDateTimeEdit class provides a widget for editing dates and times. |
40 | |
41 | \ingroup basicwidgets |
42 | \inmodule QtWidgets |
43 | |
44 | \image windows-datetimeedit.png |
45 | |
46 | QDateTimeEdit allows the user to edit dates by using the keyboard or |
47 | the arrow keys to increase and decrease date and time values. The |
48 | arrow keys can be used to move from section to section within the |
49 | QDateTimeEdit box. Dates and times appear in accordance with the |
50 | format set; see setDisplayFormat(). |
51 | |
52 | \snippet code/src_gui_widgets_qdatetimeedit.cpp 0 |
53 | |
54 | Here we've created a new QDateTimeEdit object initialized with |
55 | today's date, and restricted the valid date range to today plus or |
56 | minus 365 days. We've set the order to month, day, year. |
57 | |
58 | The range of valid values for a QDateTimeEdit is controlled by the properties |
59 | \l minimumDateTime, \l maximumDateTime, and their respective date and time |
60 | components. By default, any date-time from the start of 100 CE to the end of |
61 | 9999 CE is valid. |
62 | |
63 | \section1 Using a Pop-up Calendar Widget |
64 | |
65 | QDateTimeEdit can be configured to allow a QCalendarWidget to be used |
66 | to select dates. This is enabled by setting the calendarPopup property. |
67 | Additionally, you can supply a custom calendar widget for use as the |
68 | calendar pop-up by calling the setCalendarWidget() function. The existing |
69 | calendar widget can be retrieved with calendarWidget(). |
70 | |
71 | \section1 Keyboard Tracking |
72 | |
73 | When \l{QAbstractSpinBox::keyboardTracking}{keyboard tracking} is enabled |
74 | (the default), every keystroke of editing a field triggers signals for value |
75 | changes. |
76 | |
77 | When the allowed \l{QDateTimeEdit::setDateTimeRange}{range} is narrower than |
78 | some time interval whose end it straddles, keyboard tracking prevents the |
79 | user editing the date or time to access the later part of the interval. For |
80 | example, for a range from 29.04.2020 to 02.05.2020 and an initial date of |
81 | 30.04.2020, the user can change neither the month (May 30th is outside the |
82 | range) nor the day (April 2nd is outside the range). |
83 | |
84 | When keyboard tracking is disabled, changes are only signalled when focus |
85 | leaves the text field after edits have modified the content. This allows the |
86 | user to edit via an invalid date-time to reach a valid one. |

1570 | Many of the properties and functions provided by QTimeEdit are implemented in |
1571 | QDateTimeEdit. These are the relevant properties of this class: |
1572 | |
1573 | \list |
1574 | \li \l{QDateTimeEdit::time}{time} holds the time displayed by the widget. |
1575 | \li \l{QDateTimeEdit::minimumTime}{minimumTime} defines the minimum (earliest) time |
1576 | that can be set by the user. |
1577 | \li \l{QDateTimeEdit::maximumTime}{maximumTime} defines the maximum (latest) time |
