\brief The QSqlEditorFactory class is used to create the editors
|
|
used by QDataTable and QSqlForm.
|
|
|
|
\ingroup database
|
|
\module sql
|
|
|
|
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.
