QEditorFactory — Used to create editor widgets for QVariant data types
Inherited by QSqlEditorFactory.
QEditorFactory ( QObject * parent = 0, const char * name = 0 )
virtual QWidget * createEditor ( QWidget * parent, const QVariant & v )
Static Public Members
QEditorFactory * defaultFactory ()
void installDefaultFactory ( QEditorFactory * factory )
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.

QEditorFactory::QEditorFactory ( QObject * parent = 0, const char * name = 0 )
Constructs an editor factory with parent parent, called name.
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]

void QEditorFactory::installDefaultFactory ( QEditorFactory * factory ) [static]
