Detailed Description

Utility functions for using URLs in QMimeData.

In addition to QMimeData::setUrls() and QMimeData::urls(), these functions allow to:

  • Store two sets of URLs, the KDE-specific URLs and the equivalent local-file URLs for compatibility with non-KDE applications
  • Store KIO metadata, such as the HTTP referrer for a given URL (some websites require it for downloading e.g. an image)

◆ DecodeOption

Flags to be used in urlsFromMimeData.


When the mimedata contains both KDE-style URLs (eg: desktop:/foo) and the "most local" version of the URLs (eg: file:///home/dfaure/Desktop/foo), decode it as the KDE-style URL.

Useful in DnD code e.g. when moving icons, and the kde-style url is used as identifier for the icons.


When the mimedata contains both KDE-style URLs (eg: desktop:/foo) and the "most local" version of the URLs (eg: file:///home/dfaure/Desktop/foo), decode it as local urls.

Useful in paste/drop operations that end up calling KIO, so that urls from other users work as well.

Function Documentation

◆ exportUrlsToPortal()

bool KUrlMimeData::exportUrlsToPortal ( QMimeData * mimeData)

Export URLs through the XDG Documents Portal to allow interaction from/with sandbox code.

This implements the application/vnd.portal.filetransfer mimetype extension. When built without dbus support or the portal isn't installed on the target system, then this is no-op and returns false. Remote URLs are automatically mounted into the file system using kio-fuse

whether all URLS were exported through the portal

Definition at line 272 of file kurlmimedata.cpp.

◆ mimeDataTypes()

QStringList KUrlMimeData::mimeDataTypes ( )

Return the list of mimeTypes that can be decoded by urlsFromMimeData.

Definition at line 70 of file kurlmimedata.cpp.

◆ setMetaData()

void KUrlMimeData::setMetaData ( const MetaDataMap & metaData,
QMimeData * mimeData )
metaDataKIO metadata shipped in the mime data, which is used for instance to set a correct HTTP referrer (some websites require it for downloading e.g. an image)

Definition at line 58 of file kurlmimedata.cpp.

◆ setUrls()

void KUrlMimeData::setUrls ( const QList< QUrl > & urls,
const QList< QUrl > & mostLocalUrls,
QMimeData * mimeData )

Adds URLs and KIO metadata into the given QMimeData.

WARNING: do not call this method multiple times on the same mimedata object, you can add urls only once. But you can add other things, e.g. images, XML...

mimeDatathe QMimeData instance used to drag or copy this URL

Definition at line 49 of file kurlmimedata.cpp.

◆ urlsFromMimeData()

QList< QUrl > KUrlMimeData::urlsFromMimeData ( const QMimeData * mimeData,
DecodeOptions decodeOptions = PreferKdeUrls,
MetaDataMap * metaData = nullptr )

Extract a list of urls from the contents of mimeData.

Compared to QMimeData::urls(), this method has support for retrieving KDE-specific URLs when urls() would retrieve "most local URLs" instead as well as support for the XDG Documents Portal via the application/vnd.portal.filetransfer mimedata extension.

Decoding will fail if mimeData does not contain any URLs, or if at least one extracted URL is not valid.

When application/vnd.portal.filetransfer is set you'll only receive URLs retrieved from the XDG Documents Portal. When the portal is not available application/vnd.portal.filetransfer gets ignored.
