Manages an editor widget Widget and wrapper share the same parent.
virtual QMap< const char *, int > supportedWidgetTypes()
Returns a list of widget types which this editor widget supports.
This class should be subclassed for every configurable editor widget type.
Manages an editor widget Widget and wrapper share the same parent.
Every attribute editor widget needs a factory, which inherits this class.
virtual QgsEditorWidgetWrapper * create(QgsVectorLayer *vl, int fieldIdx, QWidget *editor, QWidget *parent) const =0
Override this in your implementation.
virtual QgsEditorConfigWidget * configWidget(QgsVectorLayer *vl, int fieldIdx, QWidget *parent) const =0
Override this in your implementation.
virtual QgsEditorWidgetConfig readConfig(const QDomElement &configElement, QgsVectorLayer *layer, int fieldIdx)
Read the config from an XML file and map it to a proper QgsEditorWidgetConfig.
virtual void writeConfig(const QgsEditorWidgetConfig &config, QDomElement &configElement, QDomDocument &doc, const QgsVectorLayer *layer, int fieldIdx)
Serialize your configuration and save it in a xml doc.
virtual QString representValue(QgsVectorLayer *vl, int fieldIdx, const QgsEditorWidgetConfig &config, const QVariant &cache, const QVariant &value) const
Create a pretty String representation of the value.
Represents a vector layer which manages a vector based data sets.
virtual QgsSearchWidgetWrapper * createSearchWidget(QgsVectorLayer *vl, int fieldIdx, QWidget *parent) const
By default a simple QgsFilterLineEdit is returned as search widget.
