Q_DECL_DEPRECATED void accept()
Alias for save()
This class contains context information for attribute editor widgets.
Manages an editor widget Widget and wrapper share the same parent.
The feature class encapsulates a single feature including its id, geometry and a list of field/values...

void setEditCommandMessage(const QString &message)
Sets the edit command message (Undo) that will be used when the dialog is accepted.
const QgsFeature & feature()
bool mIsSaving
Set to true while saving to prevent recursive saves.
Represents a vector layer which manages a vector based data sets.
