IStorageProviderKnownFolderSyncInfoSource 인터페이스

정의

네임스페이스:

Windows.Storage.Provider

클라우드 공급자가 알려진 폴더의 동기화 상태 대한 정보를 제공하기 위해 구현하는 인터페이스입니다.

예제

다음 예제에서는 스토리지 공급자의 IStorageProviderKnownFolderSyncInfoSource 구현을 보여 줍니다.

namespace winrt::CloudMirror::implementation
{
    struct MyKnownFolderInfoSource : implements<MyKnownFolderInfoSource,
            winrt::CloudMirror::IStorageProviderKnownFolderSyncInfoSource>
    {
        MyKnownFolderInfoSource();

        StorageProviderKnownFolderSyncInfo GetKnownFolderSyncInfo();

        winrt::event_token KnownFolderSyncInfoChanged(
            winrt::Windows::Foundation::TypedEventHandler<IStorageProviderKnownFolderSyncInfoSource,
            winrt::Windows::Foundation::IInspectable> const& handler);
        void KnownFolderSyncInfoChanged(winrt::event_token const& token) noexcept;

    private:
        winrt::hstring GetProviderDisplayName();
        winrt::Uri GetAvailableIcon();
        winrt::Uri GetEnrollingIcon();
        void NotifyStateChanged();

    winrt::event<winrt::TypedEventHandler<IStorageProviderKnownFolderSyncInfoSource, IInspectable>> m_changedEvent;
        std::vector<StorageProviderKnownFolderEntry> m_knownFolderEntries;
    };
}

...

using namespace winrt::Windows::Storage::Provider;

namespace winrt::CloudMirror::implementation
{
    MyKnownFolderInfoSource::MyKnownFolderInfoSource()
    {
        // The cloud provider would assess its current state and use it to
        // inform File Explorer. In this example, Documents is available for
        // backup, Pictures is currently enrolling, and Downloads is already
        // backed up (enrolled).
        winrt::StorageProviderKnownFolderEntry documents{};
        documents.KnownFolderId(FOLDERID_Documents);
        documents.Status(StorageProviderKnownFolderSyncStatus::Available);
        m_knownFolderState.push_back(documents);

    // latest known folder sync status from the cloud provider. Once returned, the
    // StorageProviderKnownFolderSyncInfo is considered immutable.
    //
    // A SyncRequested handler must be set on the returned object to be considered valid
    // and to be displayed in File Explorer.

    {
        winrt::StorageProviderKnownFolderSyncInfo info{};
        info.ProviderDisplayName(GetProviderDisplayName());
        // Setting a SyncRequested handler to respond to user action.
        auto syncRequestHandler = [](
            winrt::CloudMirror::StorageProviderKnownFolderSyncRequestArgs const& args)
        {
            // The user wants to sync some known folders with our cloud provider.
            // We can show some UI to sign in, confirm their choice, etc.
            MyStorageProviderSyncManager::ShowFolderEnrollmentUI(args.KnownFolders(), args.Source());

            // Or we can immediately start syncing the requested folders.
            MyStorageProviderSyncManager::StartSyncingFolders(args.KnownFolders(), args.Source());

설명

파일 탐색기 GetKnownFolderSyncInfoSource를 호출하여 지정된 공급자에 대한 IStorageProviderKnownFolderSyncInfoSource의 instance 가져옵니다.

이 인터페이스는 KnownFolderSyncInfoChanged 이벤트를 제공합니다. 이 이벤트는 표시 이름을 포함하여 속성 또는 폴더 상태 변경되면 앱이 발생합니다. 클라우드 공급자는 GetKnownFolderSyncInfoSource 가 이벤트를 발생시키는 즉시 호출될 것으로 예상해서는 안 됩니다. 파일 탐색기 필요에 따라 새 개체만 요청합니다.

메서드

GetKnownFolderSyncInfo()

GetKnownFolderSyncInfo는 클라우드 공급자로부터 알려진 최신 폴더 동기화 상태 가져와야 할 때마다 파일 탐색기 호출됩니다.

이벤트

KnownFolderSyncInfoChanged

알려진 폴더의 동기화 상태 변경될 때 발생하는 이벤트입니다.
