+    \class QEditorFactory qeditorfactory.h
+    \brief The QEditorFactory class is used to create editor widgets
+    for QVariant data types.
+
+    \ingroup database
+    \module sql
+
+    Each editor factory provides the createEditor() function which
+    given a QVariant will create and return a QWidget that can edit
+    that QVariant. For example if you have a QVariant::String type, a
+    QLineEdit would be the default editor returned, 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 QEditorFactory and reimplement the
+    createEditor() function.
