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).

QgsTimeEdit

QgsDateTimeEdit(parent: QWidget = None) Constructor for QgsDateTimeEdit. The current date and time is used by default. The widget is allowing null by default. If allow null is disabled, you should check allowNull before getting values from the widget.

pyqtSignal(*types, name: str = ..., revision: int = ..., arguments: Sequence = ...) -> PYQT_SIGNAL

actionEvent(self, QActionEvent)¶

allowNull(self) → bool¶

If the widget allows setting null date/time.

See also

setAllowNull()

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: PyQt5.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.

Return type:: QDateTime

dateTimeFromText(self, str) → QDateTime¶

destroy(self, destroyWindow: bool = True, destroySubWindows: bool = True)¶

disconnectNotify(self, QMetaMethod)¶

displayNull(self, updateCalendar: bool = False)¶

write the null value representation to the line edit without changing the value

Parameters:: updateCalendar (bool = False) – Flag if calendar is open and minimum date needs to be set

dragEnterEvent(self, QDragEnterEvent)¶

dragLeaveEvent(self, QDragLeaveEvent)¶

dragMoveEvent(self, QDragMoveEvent)¶

dropEvent(self, QDropEvent)¶

valueChanged¶

pyqtSignal(*types, name: str = …, revision: int = …, arguments: Sequence = …) -> PYQT_SIGNAL

types is normally a sequence of individual types. Each type is either a type object or a string that is the name of a C++ type. Alternatively each type could itself be a sequence of types each describing a different overloaded signal. name is the optional C++ name of the signal. If it is not specified then the name of the class attribute that is bound to the signal is used. revision is the optional revision of the signal that is exported to QML. If it is not specified then 0 is used. arguments is the optional sequence of the names of the signal’s arguments.

Parameters:

name (str = ...) –
revision (int = ...) –
arguments (Sequence = ...) –

Return type:

PYQT_SIGNAL

wheelEvent(self, event: QWheelEvent)¶

Parameters:: event (QWheelEvent) –
