How to get the detailed API interface of QML package

Although our Developer site has extensive API coverage, some of the apis may be incomplete, and others are evolving. To get a more detailed API, we can use the following command to get more detailed information. For example, we use the “SingleDownload” API to get more information.

\

$qmlplugindump Ubuntu. DownloadManager 0.1Copy the code

\

\

The following information is displayed:

\

Import qtquick. tooling 1.1 // This file describes the plugin-supplied types contained in the library QML tooling purposes only. // // This file was auto-generated by: // ‘qmlplugindump Ubuntu.DownloadManager 0.1’ Module {Component {name: “Ubuntu: : DownloadManager: : DownloadError” prototype: “QObject” exports: [” Error “0.1] exportMetaObjectRevisions: [0] Property { name: “type”; type: “string”; isReadonly: true } Property { name: “message”; type: “string”; isReadonly: true } } Component { name: “Ubuntu::DownloadManager::SingleDownload” prototype: “QObject” exports: [” 0.1 “SingleDownload] exportMetaObjectRevisions: [0] Property {name:” autoStart “; type: “bool” } Property { name: “errorMessage”; type: “string”; isReadonly: true } Property { name: “isCompleted”; type: “bool”; isReadonly: true } Property { name: “downloadInProgress”; type: “bool”; isReadonly: true } Property { name: “allowMobileDownload”; type: “bool” } Property { name: “throttle”; type: “qulonglong” } Property { name: “progress”; type: “int”; isReadonly: true } Property { name: “downloading”; type: “bool”; isReadonly: true } Property { name: “downloadId”; type: “string”; isReadonly: true } Property { name: “headers”; type: “QVariantMap” } Signal { name: “canceled” Parameter { name: “success”; type: “bool” } } Signal { name: “finished” Parameter { name: “path”; type: “string” } } Signal { name: “paused” Parameter { name: “success”; type: “bool” } } Signal { name: “processing” Parameter { name: “path”; type: “string” } } Signal { name: “progressReceived” Parameter { name: “received”; type: “qulonglong” } Parameter { name: “total”; type: “qulonglong” } } Signal { name: “resumed” Parameter { name: “success”; type: “bool” } } Signal { name: “started” Parameter { name: “success”; type: “bool” } } Signal { name: “errorFound” Parameter { name: “error”; type: “DownloadError&” } } Signal { name: “errorChanged” } Method { name: “registerError” Parameter { name: “error”; type: “Error”; isPointer: true } } Method { name: “bindDownload” Parameter { name: “download”; type: “Download”; isPointer: true } } Method { name: “unbindDownload” Parameter { name: “download”; type: “Download”; isPointer: true } } Method { name: “onFinished” Parameter { name: “path”; type: “string” } } Method { name: “onProgress” Parameter { name: “received”; type: “qulonglong” } Parameter { name: “total”; type: “qulonglong” } } Method { name: “onPaused” Parameter { name: “wasPaused”; type: “bool” } } Method { name: “onResumed” Parameter { name: “wasResumed”; type: “bool” } } Method { name: “onStarted” Parameter { name: “wasStarted”; type: “bool” } } Method { name: “onCanceled” Parameter { name: “wasCanceled”; type: “bool” } } Method { name: “start” } Method { name: “pause” } Method { name: “resume” } Method { name: “cancel” } Method { name: “download” Parameter { name: “url”; type: “string” } } } Component { name: “Ubuntu::DownloadManager::UbuntuDownloadManager” prototype: “QObject” exports: [” 0.1 “DownloadManager] exportMetaObjectRevisions: [0] Property {name:” autoStart “; type: “bool” } Property { name: “cleanDownloads”; type: “bool” } Property { name: “errorMessage”; type: “string”; isReadonly: true } Property { name: “downloads”; type: “QVariantList”; isReadonly: true } Signal { name: “errorChanged” } Method { name: “download” Parameter { name: “url”; type: “string” } } } }\

\

We use the “Finished” signal to get the downloaded events and handle them separately!

Another example (Push Notification)

liuxg@liuxg:~$qmlplugindump Ubuntu.PushNotifications 0.1 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.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" } } } }Copy the code
