QgsEditorConfigWidget * configWidget(QgsVectorLayer *vl, int fieldIdx, QWidget *parent) const override
Override this in your implementation.
Wraps a color widget.
This class should be subclassed for every configurable editor widget type.
Manages an editor widget Widget and wrapper share the same parent.
QgsFields fields() const FINAL
Returns the list of fields of this layer.
QgsColorWidgetFactory(const QString &name)
Constructor for QgsColorWidgetFactory, where name is a human-readable name for the factory...
Every attribute editor widget needs a factory, which inherits this class.
Encapsulate a field in an attribute table or data source.

QgsEditorWidgetWrapper * create(QgsVectorLayer *vl, int fieldIdx, QWidget *editor, QWidget *parent) const override
Override this in your implementation.
unsigned int fieldScore(const QgsVectorLayer *vl, int fieldIdx) const override
This method allows disabling this editor widget type for a certain field.
Represents a vector layer which manages a vector based data sets.
QgsField field(int fieldIdx) const
Gets field at particular index (must be in range 0..N-1)
