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.
QString widgetType(int fieldIdx) const
Get the id for the editor widget used to represent the field at the given index.
QgsEditFormConfig * editFormConfig() const
Get the configuration of the form used to represent this vector layer.
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.
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)
QgsEditorWidgetConfig widgetConfig(int fieldIdx) const
Get the configuration for the editor widget used to represent the field at the given index...
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.
virtual QVariant value() const =0
Will be used to access the widget&#39;s value.
QWidget * widget()
Access the widget managed by this wrapper.
QObject * parent() const
Represents a vector layer which manages a vector based data sets.
