    \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.
