Member Function Documentation

◆ create() [1/2]

QgsEditorWidgetWrapper * QgsEditorWidgetRegistry::create	(	const QString &	widgetId,
		QgsVectorLayer *	vl,
		int	fieldIdx,
		const QVariantMap &	config,
		QWidget *	editor,
		QWidget *	parent,
		const QgsAttributeEditorContext &	context = `QgsAttributeEditorContext()`
	)

Create an attribute editor widget wrapper of a given type for a given field.

The editor may be nullptr if you want the widget wrapper to create a default widget.

Parameters

widgetId	The id of the widget type to create an attribute editor for
vl	The vector layer for which this widget will be created
fieldIdx	The field index on the specified layer for which this widget will be created
config	A configuration which should be used for the widget creation
editor	An editor widget which will be used instead of an autocreated widget
parent	The parent which will be used for the created wrapper and the created widget
context	The editor context (not available in Python bindings)

Returns: A new widget wrapper

Definition at line 97 of file qgseditorwidgetregistry.cpp.

◆ create() [2/2]

QgsEditorWidgetWrapper * QgsEditorWidgetRegistry::create	(	QgsVectorLayer *	vl,
		int	fieldIdx,
		QWidget *	editor,
		QWidget *	parent,
		const QgsAttributeEditorContext &	context = `QgsAttributeEditorContext()`
	)

Create an attribute editor widget wrapper of the best type for a given field.

The editor may be nullptr if you want the widget wrapper to create a default widget.

Parameters

vl	The vector layer for which this widget will be created
fieldIdx	The field index on the specified layer for which this widget will be created
editor	An editor widget which will be used instead of an autocreated widget
parent	The parent which will be used for the created wrapper and the created widget
context	The editor context (not available in Python bindings)

Returns: A new widget wrapper

Definition at line 90 of file qgseditorwidgetregistry.cpp.

◆ createConfigWidget()

QgsEditorConfigWidget * QgsEditorWidgetRegistry::createConfigWidget	(	const QString &	widgetId,
		QgsVectorLayer *	vl,
		int	fieldIdx,
		QWidget *	parent
	)

Creates a configuration widget.

Parameters

widgetId	The id of the widget type to create a configuration widget for
vl	The vector layer for which this widget will be created
fieldIdx	The field index on the specified layer for which this widget will be created
parent	The parent widget for the created widget

Returns: A new configuration widget

Definition at line 148 of file qgseditorwidgetregistry.cpp.

◆ createSearchWidget()

QgsSearchWidgetWrapper * QgsEditorWidgetRegistry::createSearchWidget	(	const QString &	widgetId,
		QgsVectorLayer *	vl,
		int	fieldIdx,
		const QVariantMap &	config,
		QWidget *	parent,
		const QgsAttributeEditorContext &	context = `QgsAttributeEditorContext()`
	)

Definition at line 128 of file qgseditorwidgetregistry.cpp.

◆ factories()

QMap< QString, QgsEditorWidgetFactory * > QgsEditorWidgetRegistry::factories ( )

Gets access to all registered factories.

Returns: All ids and factories

Definition at line 167 of file qgseditorwidgetregistry.cpp.

◆ factory()

QgsEditorWidgetFactory * QgsEditorWidgetRegistry::factory ( const QString & widgetId )

Gets a factory for the given widget type id.

Returns: A factory or nullptr if not existent

Definition at line 172 of file qgseditorwidgetregistry.cpp.

◆ findBest()

QgsEditorWidgetSetup QgsEditorWidgetRegistry::findBest	(	const QgsVectorLayer *	vl,
		const QString &	fieldName
	)		const

Find the best editor widget and its configuration for a given field.

Parameters

vl	The vector layer for which this widget will be created
fieldName	The field name on the specified layer for which this widget will be created

Returns: The id of the widget type to use and its config

Definition at line 76 of file qgseditorwidgetregistry.cpp.

◆ initEditors()

void QgsEditorWidgetRegistry::initEditors	(	QgsMapCanvas *	mapCanvas = `nullptr`,
		QgsMessageBar *	messageBar = `nullptr`
	)

Registers all the default widgets.

Only call this once on startup of an application.

Parameters

mapCanvas	Specify a map canvas with which the widgets (relation reference) work
messageBar	Specify a message bar on which messages by widgets will be shown while working with the map canvas

Note: Not required for plugins, the QGIS application does that already

Since: QGIS 2.8

Definition at line 50 of file qgseditorwidgetregistry.cpp.

◆ name()

QString QgsEditorWidgetRegistry::name ( const QString & widgetId )

Gets the human readable name for a widget type.

Parameters

widgetId The widget type to get the name for

Returns: A human readable name

Definition at line 157 of file qgseditorwidgetregistry.cpp.

◆ registerAutoConfPlugin()

void QgsEditorWidgetRegistry::registerAutoConfPlugin ( QgsEditorWidgetAutoConfPlugin * plugin )

inline

Register a new auto-conf plugin.

Parameters

plugin The plugin (ownership is transferred)

Definition at line 182 of file qgseditorwidgetregistry.h.

◆ registerWidget()

bool QgsEditorWidgetRegistry::registerWidget	(	const QString &	widgetId,
		QgsEditorWidgetFactory *	widgetFactory
	)

Register a new widget factory with the given id.

Parameters

widgetId	The id which will be used later to refer to this widget type
widgetFactory	The factory which will create this widget type

Returns: true, if successful, false, if the widgetId is already in use or widgetFactory is nullptr
