Detailed Description

Wraps a date time widget.

Users will be able to choose date and time from an appropriate dialog.

Options:

display_format The format used to represent the date/time to the user.
calendar_popup If true, will offer a calendar popup.
allow_null If true, will allow NULL values. Requires QgsDateTimeEdit as widget (Be aware if you work with .ui files).
field_format The format used to save the date/time.

Note: not available in Python bindings

Constructor & Destructor Documentation

◆ QgsDateTimeEditWrapper()

QgsDateTimeEditWrapper::QgsDateTimeEditWrapper	(	QgsVectorLayer *	layer,
		int	fieldIdx,
		QWidget *	editor,
		QWidget *	parent = `nullptr`
	)

explicit

Constructor for QgsDateTimeEditWrapper.

The layer and fieldIdx arguments specify the vector layer field associated with the wrapper.

The editor argument indicates the editor widget to use with the wrapper. This can be nullptr if a new widget should be autogenerated.

A parent widget for this widget wrapper and the created widget can also be specified.

Member Function Documentation

◆ createWidget()

QWidget * QgsDateTimeEditWrapper::createWidget ( QWidget * parent )

overridevirtual

This method should create a new widget with the provided parent.

This will only be called if the form did not already provide a widget, so it is not guaranteed to be called! You should not do initialization stuff, which also has to be done for custom editor widgets inside this method. Things like filling comboboxes and assigning other data which will also be used to make widgets on forms created in the QtDesigner usable should be assigned in initWidget().

Parameters

parent You should set this parent on the created widget.

Returns: A new widget

Implements QgsWidgetWrapper.

Definition at line 37 of file qgsdatetimeeditwrapper.cpp.

◆ initWidget()

void QgsDateTimeEditWrapper::initWidget ( QWidget * editor )

overridevirtual

This method should initialize the editor widget with runtime data.

Fill your comboboxes here.

Parameters

editor The widget which will represent this attribute editor in a form.

Reimplemented from QgsWidgetWrapper.

Definition at line 44 of file qgsdatetimeeditwrapper.cpp.

◆ setEnabled

void QgsDateTimeEditWrapper::setEnabled ( bool enabled )

overrideslot

Definition at line 282 of file qgsdatetimeeditwrapper.cpp.

◆ showIndeterminateState()

void QgsDateTimeEditWrapper::showIndeterminateState ( )

overridevirtual

Sets the widget to display in an indeterminate "mixed value" state.

Since: QGIS 2.16

Reimplemented from QgsEditorWidgetWrapper.

Definition at line 110 of file qgsdatetimeeditwrapper.cpp.

◆ valid()

bool QgsDateTimeEditWrapper::valid ( ) const

overridevirtual

Returns true if the widget has been properly initialized.

This acts as hint for the calling party if this wrapper can be used after initializing it. If it cannot be used this is a hint to the caller that he may try to find another suitable widget type instead.

Returns: Validity status of this widget.

Since: QGIS 2.12

Implements QgsWidgetWrapper.

Definition at line 105 of file qgsdatetimeeditwrapper.cpp.

◆ value()

QVariant QgsDateTimeEditWrapper::value ( ) const

overridevirtual

Will be used to access the widget's value.

Read the value from the widget and return it properly formatted to be saved in the attribute.

If an invalid variant is returned this will be interpreted as no change. Be sure to return a NULL QVariant if it should be set to NULL.

Returns: The current value the widget represents

Implements QgsEditorWidgetWrapper.
