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 DOCUMENTATIONQSqlEditorFactory::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 \a factory, and
destroys it when it is no longer needed.
