如何得到QML package的详细API接口

来源：互联网发布：python 硬件开发编辑：程序博客网时间：2024/05/29 17:44

尽管我们的developer网站有丰富的API介绍，但是，有些API的介绍可能并不全，有些API也在不断地演进中。为了得到更详细的API，我们可以通过如下的命令来得到更加详细的信息。比如我们对“SingleDownload”API来得到更加多的信息。

$qmlplugindump Ubuntu.DownloadManager 0.1

显示的结果如下：

import QtQuick.tooling 1.1

// This file describes the plugin-supplied types contained in the library.
// It is used for QML tooling purposes only.
//
// This file was auto-generated by:
// 'qmlplugindump Ubuntu.DownloadManager 0.1'

Signal { name: "errorChanged" }
Method {
name: "download"
Parameter { name: "url"; type: "string" }
}
}
}

我们通过使用“finished”信号可以得到下载完成的事件而进行分别的处理！

另外一个例子（Push notification)

liuxg@liuxg:~$ qmlplugindump Ubuntu.PushNotifications 0.1import QtQuick.tooling 1.1// This file describes the plugin-supplied types contained in the library.// It is used for QML tooling purposes only.//// This file was auto-generated by:// 'qmlplugindump Ubuntu.PushNotifications 0.1'Module {    Component {        name: "PushClient"        prototype: "QObject"        exports: ["PushClient 0.1"]        exportMetaObjectRevisions: [0]        Property { name: "appId"; type: "string" }        Property { name: "token"; type: "string"; isReadonly: true }        Property { name: "notifications"; type: "QStringList"; isReadonly: true }        Property { name: "status"; type: "string"; isReadonly: true }        Property { name: "persistent"; type: "QStringList"; isReadonly: true }        Property { name: "count"; type: "int" }        Signal {            name: "countChanged"            Parameter { type: "int" }        }        Signal {            name: "notificationsChanged"            Parameter { type: "QStringList" }        }        Signal {            name: "persistentChanged"            Parameter { type: "QStringList" }        }        Signal {            name: "appIdChanged"            Parameter { type: "string" }        }        Signal {            name: "error"            Parameter { type: "string" }        }        Signal {            name: "tokenChanged"            Parameter { type: "string" }        }        Signal {            name: "statusChanged"            Parameter { type: "string" }        }        Method { name: "getNotifications" }        Method {            name: "notified"            Parameter { name: "appId"; type: "string" }        }        Method { name: "emitError" }        Method {            name: "clearPersistent"            Parameter { name: "tags"; type: "QStringList" }        }    }}
