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