扩展 QML - 方法范例

方法支持。

此范例构建于：

• 扩展 QML - 继承与强制转换范例
• 扩展 QML - 对象和列表特性类型范例
• 扩展 QML - 添加类型范例

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

    Q_INVOKABLE void invite(const QString &name);
					

在 example.qml ， 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")
}
