## Property Documentation

Holds the download item's ID.

mimeType : string

Holds the MIME type of the download.

This QML property was introduced in QtWebEngine 1.2.

Holds the full target path where data is being downloaded to.

The path includes the file name. The default suggested path is the standard download location and file name is deduced not to overwrite already existing files.

The download path can only be set in the `WebEngineProfile.onDownloadRequested` handler before the download is accepted.

See also WebEngineProfile::downloadRequested() and accept().

receivedBytes : int

Holds the amount of data in bytes that has been downloaded so far.

Constant | Description

`WebEngineDownloadItem.UnknownSaveFormat` | This is not a request for downloading a complete web page.
`WebEngineDownloadItem.SingleHtmlSaveFormat` | The page is saved as a single HTML page. Resources such as images are not saved.
`WebEngineDownloadItem.CompleteHtmlSaveFormat` | The page is saved as a complete HTML page, for example a directory containing the single HTML page and the resources.

If `Content-Disposition` is present in the reply, the web server is indicating that the client should prompt the user to save the content regardless of the content type.
