Class: QgsFileDownloaderDialog¶

QgsFileDownloaderDialog is a QProgressDialog subclass which handles file downloads and user feedback.

Internally, it uses QgsFileDownloader to handle the download, while showing progress via a progress dialog and supporting cancellation.

Note

Until QGIS 3.0 this functionality was available via QgsFileDownloader.
