+ used by QDataTable and QSqlForm.
+
+ \ingroup database
+ \module sql
+
+ QSqlEditorFactory is used by QDataTable and QSqlForm to
+ automatically create appropriate editors for a given QSqlField.
+ For example if the field is a QVariant::String a QLineEdit would
+ be the default editor, whereas a QVariant::Int's default editor
+ would be a QSpinBox.
+
+ If you want to create different editors for fields with the same
+ data type, subclass QSqlEditorFactory and reimplement the
+ createEditor() function.
