Class: QgsDateTimeEdit

class qgis.gui.QgsDateTimeEdit

Bases: PyQt5.QtWidgets.QDateTimeEdit

The QgsDateTimeEdit class is a QDateTimeEdit with the capability of setting/reading null date/times.

Warning

You should use the signal valueChanged of this subclass rather than QDateTimeEdit.dateTimeChanged. (If you consequently connect parent’s dateTimeChanged signal and call dateTime() afterwards there is no guarantee that NULL values will be correctly handled).

Return type

bool

changeEvent(self, QEvent)
childEvent(self, QChildEvent)
clear(self)

Set the current date as NULL.

Note

If the widget is not configured to accept NULL dates, this will have no effect.

closeEvent(self, QCloseEvent)
connectNotify(self, QMetaMethod)
contextMenuEvent(self, QContextMenuEvent)
create(self, window: sip.voidptr = 0, initializeWindow: bool = True, destroyOldWindow: bool = True)
customEvent(self, QEvent)
date(self)QDate

Returns the date which can be a null date.

New in version 3.10.

Return type

QDate

dateTime(self)QDateTime

Returns the date time which can be a null date/time.

Note

Before QGIS 3.10, you mustn’t call date() or time() because they can’t return a NULL value.

Note

Since QDateTimeEdit.dateTime() is not virtual, dateTime must be called for QgsDateTimeEdit.

destroy(self, destroyWindow: bool = True, destroySubWindows: bool = True)
disconnectNotify(self, QMetaMethod)
displayNull(self, updateCalendar: bool = False)
