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
widgetIdThe id of the widget type to create an attribute editor for
vlThe vector layer for which this widget will be created
fieldIdxThe field index on the specified layer for which this widget will be created
configA configuration which should be used for the widget creation
editorAn editor widget which will be used instead of an autocreated widget
parentThe parent which will be used for the created wrapper and the created widget
contextThe editor context (not available in Python bindings)
Returns
A new widget wrapper

Definition at line 102 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
vlThe vector layer for which this widget will be created
fieldIdxThe field index on the specified layer for which this widget will be created
editorAn editor widget which will be used instead of an autocreated widget
parentThe parent which will be used for the created wrapper and the created widget
contextThe editor context (not available in Python bindings)
Returns
A new widget wrapper

Definition at line 95 of file qgseditorwidgetregistry.cpp.

◆ createConfigWidget()

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

Creates a configuration widget.

Parameters
widgetIdThe id of the widget type to create a configuration widget for
vlThe vector layer for which this widget will be created
fieldIdxThe field index on the specified layer for which this widget will be created
parentThe parent widget for the created widget
Returns
A new configuration widget

Definition at line 153 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 133 of file qgseditorwidgetregistry.cpp.

◆ factories()

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

Gets access to all registered factories.

Returns
All ids and factories

Definition at line 172 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 177 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
vlThe vector layer for which this widget will be created
fieldNameThe 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 81 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
mapCanvasSpecify a map canvas with which the widgets (relation reference) work
messageBarSpecify 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

Definition at line 53 of file qgseditorwidgetregistry.cpp.

◆ name()

QString QgsEditorWidgetRegistry::name ( const QString &  widgetId)

Gets the human readable name for a widget type.

Parameters
widgetIdThe widget type to get the name for
Returns
A human readable name

Definition at line 162 of file qgseditorwidgetregistry.cpp.

◆ registerAutoConfPlugin()

void QgsEditorWidgetRegistry::registerAutoConfPlugin ( QgsEditorWidgetAutoConfPlugin plugin)
inline

Register a new auto-conf plugin.

Parameters
pluginThe plugin (ownership is transferred)

Definition at line 181 of file qgseditorwidgetregistry.h.

◆ registerWidget()

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

Register a new widget factory with the given id.

Parameters
widgetIdThe id which will be used later to refer to this widget type
widgetFactoryThe factory which will create this widget type
Returns
true, if successful, false, if the widgetId is already in use or widgetFactory is nullptr
