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.
QVariant::Type type
Definition: qgsfield.h:58
QgsField field(int fieldIdx) const
Returns the field at particular index (must be in range 0..N-1).
Definition: qgsfields.cpp:168
unsigned int fieldScore(const QgsVectorLayer *vl, int fieldIdx) const override
This method allows disabling this editor widget type for a certain field.
QgsEditorWidgetWrapper * create(QgsVectorLayer *vl, int fieldIdx, QWidget *editor, QWidget *parent) const override
Override this in your implementation.
QgsUuidWidgetFactory(const QString &name)
Constructor for QgsUuidWidgetFactory, where name is a human-readable name for the factory.
QgsEditorConfigWidget * configWidget(QgsVectorLayer *vl, int fieldIdx, QWidget *parent) const override
Override this in your implementation.
Wraps a uuid widget.
Represents a vector layer which manages a vector based data sets.
QgsFields fields() const FINAL
Returns the list of fields of this layer.
