+ \brief The Q3SqlEditorFactory class is used to create the editors
+ used by Q3DataTable and Q3SqlForm.
+
+ \compat
+
+ Q3SqlEditorFactory is used by Q3DataTable and Q3SqlForm 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 Q3SqlEditorFactory and reimplement the
+ createEditor() function.
