This class should be subclassed for every configurable editor widget type.
Every attribute editor widget needs a factory, which inherits this class.
Manages an editor widget Widget and wrapper share the same parent.
Encapsulate a field in an attribute table or data source.

QgsField at(int i) const
Returns the field at particular index (must be in range 0..N-1).
QHash< const char *, int > supportedWidgetTypes() override
Returns a list of widget types which this editor widget supports.
QgsEditorConfigWidget * configWidget(QgsVectorLayer *vl, int fieldIdx, QWidget *parent) const override
Override this in your implementation.
QgsRangeWidgetFactory(const QString &name)
Constructor for QgsRangeWidgetFactory, where name is a human-readable name for the factory.
QgsEditorWidgetWrapper * create(QgsVectorLayer *vl, int fieldIdx, QWidget *editor, QWidget *parent) const override
Override this in your implementation.
Wraps a range widget.
Represents a vector layer which manages a vector based data sets.
