const QgsEditorWidgetConfig editorWidgetV2Config(int fieldIdx) const
Get the configuration for the editor widget used to represent the field at the given index...
static bool retrieveValue(QWidget *widget, QgsVectorLayer *vl, int idx, QVariant &value)
This class contains context information for attribute editor widgets.
Manages an editor widget Widget and wrapper share the same parent.
virtual QVariant value()=0
Will be used to access the widget's value.
static QgsEditorWidgetRegistry * instance()
This class is a singleton and has therefore to be accessed with this method instead of a constructor...
QgsEditorWidgetWrapper * create(const QString &widgetId, QgsVectorLayer *vl, int fieldIdx, const QgsEditorWidgetConfig &config, QWidget *editor, QWidget *parent, const QgsAttributeEditorContext &context=QgsAttributeEditorContext())
Create an attribute editor widget wrapper of a given type for a given field.
const QString editorWidgetV2(int fieldIdx) const
Get the id for the editor widget used to represent the field at the given index.
static QgsEditorWidgetWrapper * fromWidget(QWidget *widget)
Will return a wrapper for a given widget.
static bool setValue(QWidget *widget, QgsVectorLayer *vl, int idx, const QVariant &value)
virtual void setValue(const QVariant &value)=0
Is called, when the value of the widget needs to be changed.
static Q_DECL_DEPRECATED QWidget * createAttributeEditor(QWidget *parent, QWidget *editor, QgsVectorLayer *vl, int idx, const QVariant &value, QMap< int, QWidget * > &proxyWidgets)
Creates or prepares a attribute editor widget.
QWidget * widget()
Access the widget managed by this wrapper.
Represents a vector layer which manages a vector based data sets.
