Descripción detallada

The QSqlEditorFactory class is used to create the editors used by QDataTable and QSqlForm.

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.
