# Extending QML - Methods Example

Methods Support.

This example builds on:

- Extending QML - Inheritance and Coercion Example
- Extending QML - Object and List Property Types Example
- Extending QML - Adding Types Example

The Methods Example has an additional method in the `BirthdayParty` class: `invite()`. `invite()` is declared with Q_INVOKABLE so that it can be called from QML.

         Q_INVOKABLE void invite(const QString &name);

In `example.qml`, the `invite()` method is called in the Component.onCompleted signal handler:

     import QtQuick 2.0
     import People 1.0

     BirthdayParty {
         host: Person {
             name: "Bob Jones"
             shoeSize: 12
         }
         guests: [
             Person { name: "Leo Hodges" },
             Person { name: "Jack Smith" },
             Person { name: "Anne Brown" }
         ]

         Component.onCompleted: invite("William Green")
     }
