\brief The TQEditorFactory class is used to create editor widgets
for TQVariant data types.
\ingroup database
\module sql
Each editor factory provides the createEditor() function which
given a TQVariant will create and return a TQWidget that can edit
that TQVariant. For example if you have a TQVariant::String type, a
TQLineEdit would be the default editor returned, whereas a
TQVariant::Int's default editor would be a TQSpinBox.
If you want to create different editors for fields with the same
data type, subclass TQEditorFactory and reimplement the
createEditor() function.
