virtual QgsSearchWidgetWrapper * createSearchWidget(QgsVectorLayer *vl, int fieldIdx, QWidget *parent) const
By default a simple QgsFilterLineEdit is returned as search widget.
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 unsigned int fieldScore(const QgsVectorLayer *vl, int fieldIdx) const
This method allows disabling this editor widget type for a certain field.
Represents a vector layer which manages a vector based data sets.
