The QDateTimeEdit class combines a QDateEdit and QTimeEdit widget into a single widget for editing datetimes.
QDateTimeEdit consists of a QDateEdit and QTimeEdit 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 QDateTimeEdit 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 QDateEdit::setOrder() to change this. Times appear in the order hours, minutes, seconds using the 24 hour clock.
It is recommended that the QDateTimeEdit is initialised with a datetime, e.g.
QDateTimeEdit *dateTimeEdit = new QDateTimeEdit( QDateTime::currentDateTime(), this ); dateTimeEdit->dateEdit()->setRange( QDateTime::currentDate(), QDateTime::currentDate().addDays( 7 ) );
Here we've created a new QDateTimeEdit 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 QDateEdit widget consists of three 'sections', one each for the year, month and day. Similarly a QTimeEdit 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.
datetimewidgets.png Date Time Widgets
| QDateTimeEdit::QDateTimeEdit | ( | QWidget * | parent = 0, |
| const char * | name = 0 |
||
| ) |
Constructs an empty datetime edit with parent parent and called name.
| QDateTimeEdit::QDateTimeEdit | ( | const QDateTime & | datetime, |
| QWidget * | parent = 0, |
||
| const char * | name = 0 |
||
| ) |
Esta es una función miembro sobrecargada que se suministra por conveniencia. Difiere de la anterior función solamente en los argumentos que acepta. Constructs a datetime edit with the initial value datetime, parent parent and called name.
| QDateTimeEdit::~QDateTimeEdit | ( | ) |
Destroys the object and frees any allocated resources.
| QDateTimeEdit::QDateTimeEdit | ( | QWidget * | parent = 0, |
| const char * | name = 0 |
||
| ) |
| QDateTimeEdit::QDateTimeEdit | ( | const QDateTime & | datetime, |
| QWidget * | parent = 0, |
||
| const char * | name = 0 |
||
| ) |
| QDateTimeEdit::~QDateTimeEdit | ( | ) |
| bool QDateTimeEdit::autoAdvance | ( | ) | const |
Returns TRUE if auto-advance is enabled, otherwise returns FALSE.
| bool QDateTimeEdit::autoAdvance | ( | ) | const |
| QDateEdit* QDateTimeEdit::dateEdit | ( | ) | [inline] |
| QDateEdit * QDateTimeEdit::dateEdit | ( | ) | [inline] |
Returns the internal widget used for editing the date part of the datetime.
| QDateTime QDateTimeEdit::dateTime | ( | ) | const |
| QDateTime QDateTimeEdit::dateTime | ( | ) | const |
| void QDateTimeEdit::init | ( | ) | [protected] |
| void QDateTimeEdit::init | ( | ) | [protected] |
| void QDateTimeEdit::newValue | ( | const QTime & | t | ) | [protected, slot] |
| void QDateTimeEdit::newValue | ( | const QDate & | d | ) | [protected, slot] |
| void QDateTimeEdit::newValue | ( | const QTime & | t | ) | [protected, slot] |
| void QDateTimeEdit::newValue | ( | const QDate & | d | ) | [protected, slot] |
| void QDateTimeEdit::resizeEvent | ( | QResizeEvent * | ) | [protected, virtual] |
Intercepts and handles resize events which have special meaning for the QDateTimeEdit.
Reimplementado de QWidget.
| void QDateTimeEdit::resizeEvent | ( | QResizeEvent * | ) | [protected, virtual] |
This event handler can be reimplemented in a subclass to receive widget resize events. When resizeEvent() is called, the widget already has its new geometry. The old size is accessible through QResizeEvent::oldSize().
The widget will be erased and receive a paint event immediately after processing the resize event. No drawing need be (or should be) done inside this handler.
Widgets that have been created with the WNoAutoErase flag will not be erased. Nevertheless, they will receive a paint event for their entire area afterwards. Again, no drawing needs to be done inside this handler.
The default implementation calls updateMask() if the widget has automatic masking enabled.

| void QDateTimeEdit::setAutoAdvance | ( | bool | advance | ) | [virtual] |
Sets the auto advance property of the editor to advance. If set to TRUE, the editor will automatically advance focus to the next date or time section if the user has completed a section.
| virtual void QDateTimeEdit::setAutoAdvance | ( | bool | advance | ) | [virtual] |
| virtual void QDateTimeEdit::setDateTime | ( | const QDateTime & | dt | ) | [virtual, slot] |
| void QDateTimeEdit::setDateTime | ( | const QDateTime & | dt | ) | [virtual, slot] |
| QTimeEdit* QDateTimeEdit::timeEdit | ( | ) | [inline] |
| QTimeEdit * QDateTimeEdit::timeEdit | ( | ) | [inline] |
Returns the internal widget used for editing the time part of the datetime.
| void QDateTimeEdit::valueChanged | ( | const QDateTime & | datetime | ) | [signal] |
This signal is emitted every time the date or time changes. The datetime argument is the new datetime.
| void QDateTimeEdit::valueChanged | ( | const QDateTime & | datetime | ) | [signal] |
QDateTime QDateTimeEdit::dateTime [read, write] |
the editor's datetime value
The datetime edit's datetime which may be an invalid datetime.
