virtual void setFeature(const QgsFeature &feature)=0
Is called, when the value of the widget needs to be changed.
virtual bool valid() const =0
Return true if the widget has been properly initialized.
virtual QWidget * createWidget(QWidget *parent)=0
This method should create a new widget with the provided parent.

This method should initialize the editor widget with runtime data.
Represents a vector layer which manages a vector based data sets.
Manages an editor widget Widget and wrapper share the same parent.
