# qeditorfactory(3qt)

Used to create editor widgets for QVariant data types

## NAME

QEditorFactory - Used to create editor widgets for QVariant data types

## SYNOPSIS

`#include <qeditorfactory.h>`

Inherits QObject.

Inherited by QSqlEditorFactory.

### Public Members

**QEditorFactory ( QObject \* parent = 0, const char \* name = 0 )**\
 **~QEditorFactory ()**\
 **virtual QWidget \* createEditor ( QWidget \* parent, const QVariant & v )**\

### Static Public Members

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

## DESCRIPTION

The QEditorFactory class is used to create editor widgets for QVariant data types.

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.

See also Database Classes.

## MEMBER FUNCTION DOCUMENTATION

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

Constructs an editor factory with parent *parent*, called *name*.

## QEditorFactory::~QEditorFactory ()

Destroys the object and frees any allocated resources.

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

Creates and returns the appropriate editor for the QVariant *v*. If the QVariant is invalid, 0 is returned. The *parent* is passed to the appropriate editor's constructor.

Reimplemented in QSqlEditorFactory.

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

Returns an instance of a default editor factory.

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

Replaces the default editor factory with *factory*. *QEditorFactory takes ownership of factory, and destroys it when it is no longer needed.*
