This class should be subclassed for every configurable editor widget type.
Manages an editor widget Widget and wrapper share the same parent.
Every attribute editor widget needs a factory, which inherits this class.
virtual QgsEditorWidgetWrapper * create(QgsVectorLayer *vl, int fieldIdx, QWidget *editor, QWidget *parent) const =0
Override this in your implementation.
virtual QgsEditorConfigWidget * configWidget(QgsVectorLayer *vl, int fieldIdx, QWidget *parent) const =0
Override this in your implementation.
virtual QgsEditorWidgetConfig readConfig(const QDomElement &configElement, QgsVectorLayer *layer, int fieldIdx)
Read the config from an XML file and map it to a proper QgsEditorWidgetConfig.
virtual void writeConfig(const QgsEditorWidgetConfig &config, QDomElement &configElement, QDomDocument &doc, const QgsVectorLayer *layer, int fieldIdx)
Serialize your configuration and save it in a xml doc.
Represents a vector layer which manages a vector based data sets.
