QgsEditorWidgetWrapper * create(QgsVectorLayer *vl, int fieldIdx, QWidget *editor, QWidget *parent) const override
Override this in your implementation.
This class should be subclassed for every configurable editor widget type.
#define QGSDATETIMEEDIT_DATEFORMAT
QString attribute(const QString &name, const QString &defValue) const
void writeConfig(const QgsEditorWidgetConfig &config, QDomElement &configElement, QDomDocument &doc, const QgsVectorLayer *layer, int fieldIdx) override
Serialize your configuration and save it in a xml doc.
Manages an editor widget Widget and wrapper share the same parent.
Wraps a date time widget.
bool isNull() const
void setAttribute(const QString &name, const QString &value)
Every attribute editor widget needs a factory, which inherits this class.
QString representValue(QgsVectorLayer *vl, int fieldIdx, const QgsEditorWidgetConfig &config, const QVariant &cache, const QVariant &value) const override
Create a pretty String representation of the value.

QgsEditorWidgetConfig readConfig(const QDomElement &configElement, QgsVectorLayer *layer, int fieldIdx) override
Read the config from an XML file and map it to a proper QgsEditorWidgetConfig.
iterator insert(const Key &key, const T &value)
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.
