Description
WebKitDownload carries information about a download request, including a WebKitNetworkRequest object. The application may use this object to control the download process, or to simply figure out what is to be downloaded, and do it itself.
Functions
webkit_download_cancel ()
void
webkit_download_cancel (WebKitDownload *download
);
Cancels the download. Calling this will not free the
WebKitDownload object, so you still need to call
g_object_unref()
on it, if you are the owner of a reference. Notice
that cancelling the download provokes the emission of the
WebKitDownload::error signal, reporting that the download was
cancelled.
Since: 1.1.2
webkit_download_get_current_size ()
guint64
webkit_download_get_current_size (WebKitDownload *download
);
Current already downloaded size.
Since: 1.1.2
webkit_download_get_destination_uri ()
const gchar *
webkit_download_get_destination_uri (WebKitDownload *download
);
Obtains the URI to which the downloaded file will be written. This
must have been set by the application before calling
webkit_download_start()
, and may be NULL
.
Since: 1.1.2
webkit_download_get_elapsed_time ()
gdouble
webkit_download_get_elapsed_time (WebKitDownload *download
);
Elapsed time for the download in seconds, including any fractional part. If the download is finished, had an error or was cancelled this is the time between its start and the event.
Since: 1.1.2
webkit_download_get_network_request ()
WebKitNetworkRequest *
webkit_download_get_network_request (WebKitDownload *download
);
Retrieves the WebKitNetworkRequest object that backs the download process.

webkit_download_get_network_response (WebKitDownload *download
);

const gchar *
webkit_download_get_suggested_filename
(WebKitDownload *download

Since: 1.1.2
webkit_download_get_total_size ()
guint64
webkit_download_get_total_size (WebKitDownload *download
);
Returns the expected total size of the download. This is expected because the server may provide incorrect or missing Content-Length. Notice that this may grow over time, as it will be always the same as current_size in the cases where current size surpasses it.
