This class should be subclassed for every configurable editor widget type.
Manages an editor widget Widget and wrapper share the same parent.
QgsListWidgetFactory(const QString &name)
Constructor.
QgsFields fields() const override
Returns the list of fields of this layer.
Every attribute editor widget needs a factory, which inherits this class.
QgsEditorWidgetWrapper * create(QgsVectorLayer *vl, int fieldIdx, QWidget *editor, QWidget *parent) const override
Override this in your implementation.
Encapsulate a field in an attribute table or data source.
Definition: qgsfield.h:48
unsigned int fieldScore(const QgsVectorLayer *vl, int fieldIdx) const override
This method allows disabling this editor widget type for a certain field.
QVariant::Type subType() const
If the field is a collection, gets its element&#39;s type.
Definition: qgsfield.cpp:99
Wraps a list widget.
QgsEditorConfigWidget * configWidget(QgsVectorLayer *vl, int fieldIdx, QWidget *parent) const override
Override this in your implementation.
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)
Definition: qgsfields.cpp:150
QVariant::Type type
