### Public Members

**QSqlEditorFactory ( QObject \* parent = 0, const char \* name = 0 )**\
 **~QSqlEditorFactory ()**\
 **virtual QWidget \* createEditor ( QWidget \* parent, const QVariant & variant )**\
 **virtual QWidget \* createEditor ( QWidget \* parent, const QSqlField \* field )**\

### Static Public Members

**QSqlEditorFactory \* defaultFactory ()**\
 **void installDefaultFactory ( QSqlEditorFactory \* factory )**\

## DESCRIPTION

The QSqlEditorFactory class is used to create the editors used by QDataTable and QSqlForm.

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.

See also QDataTable, QSqlForm, and Database Classes.

## MEMBER FUNCTION DOCUMENTATION

## QSqlEditorFactory::QSqlEditorFactory ( QObject \* parent = 0, const char \* name = 0 )

Constructs a SQL editor factory with parent *parent*, called *name*.

## QSqlEditorFactory::~QSqlEditorFactory ()

Destroys the object and frees any allocated resources.

## QWidget \* QSqlEditorFactory::createEditor ( QWidget \* parent, const QVariant & variant )` [virtual]`

Creates and returns the appropriate editor widget for the QVariant *variant*.

The widget that is returned has the parent *parent* (which may be zero). If *variant* is invalid, 0 is returned.

Reimplemented from QEditorFactory.

## QWidget \* QSqlEditorFactory::createEditor ( QWidget \* parent, const QSqlField \* field )` [virtual]`

This is an overloaded member function, provided for convenience. It behaves essentially like the above function.

Creates and returns the appropriate editor for the QSqlField *field*.

## QSqlEditorFactory \* QSqlEditorFactory::defaultFactory ()` [static]`

Returns an instance of a default editor factory.

## void QSqlEditorFactory::installDefaultFactory ( QSqlEditorFactory \* factory )` [static]`

Replaces the default editor factory with *factory*. All QDataTable and QSqlForm instantiations will use this new factory for creating field editors. *QSqlEditorFactory takes ownership of &#92;a factory, and destroys it when it is no longer needed.*
