# Extending QML - Extension Objects Example

This example builds on:

- Extending QML - Adding Types Example

Shows how to use qmlRegisterExtendedType() to provide an extension object to a QLineEdit without modifying or subclassing. The QML engine instantiates a QLineEdit and sets a property that only exists on the extension type. The extension type performs calls on the QLineEdit that otherwise will not be accessible to the QML engine.
