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.

QMetaType::Type type
Definition qgsfield.h:60
QString typeName() const
Gets the field type.
Definition qgsfield.cpp:161
QgsField field(int fieldIdx) const
Returns the field at particular index (must be in range 0..N-1).
QgsEditorWidgetWrapper * create(QgsVectorLayer *vl, int fieldIdx, QWidget *editor, QWidget *parent) const override
Override this in your implementation.
QgsGeometryWidgetFactory(const QString &name, QgsMessageBar *messageBar)
Constructor for QgsGeometryWidgetFactory, where name is a human-readable name for the factory.
unsigned int fieldScore(const QgsVectorLayer *vl, int fieldIdx) const override
This method allows disabling this editor widget type for a certain field.
QgsEditorConfigWidget * configWidget(QgsVectorLayer *vl, int fieldIdx, QWidget *parent) const override
Override this in your implementation.
Widget wrapper for geometry fields.
A bar for displaying non-blocking messages to the user.
Represents a vector layer which manages a vector based data sets.
