    \class Q3SqlPropertyMap
    \brief The Q3SqlPropertyMap class is used to map widgets to SQL fields.

    \compat

    The SQL module uses Qt \link properties.html object
    properties\endlink to insert and extract values from editor
    widgets.

    This class is used to map editors to SQL fields. This works by
    associating SQL editor class names to the properties used to
    insert and extract values to/from the editor.

    For example, a QLineEdit can be used to edit text strings and
    other data types in Q3DataTables or Q3SqlForms. Several properties
    are defined in QLineEdit, but only the \e text property is used to
    insert and extract text from a QLineEdit. Both Q3DataTable and
    Q3SqlForm use the global Q3SqlPropertyMap for inserting and
    extracting values to and from an editor widget. The global
    property map defines several common widgets and properties that
    are suitable for many applications. You can add and remove widget
    properties to suit your specific needs.

    If you want to use custom editors with your Q3DataTable or
    Q3SqlForm, you must install your own Q3SqlPropertyMap for that table
    or form. Example:

    \snippet doc/src/snippets/code/src_qt3support_sql_q3sqlpropertymap.cpp 0

    You can also replace the global Q3SqlPropertyMap that is used by
    default. (Bear in mind that Q3SqlPropertyMap takes ownership of the
    new default map.)
