Member Function Documentation

downloadFile()

std::shared_ptr< QXmppFileDownload > QXmppFileSharingManager::downloadFile	(	const QXmppFileShare &	fileShare,
		std::unique_ptr< QIODevice >	output
	)

Download a file from a QXmppFileShare.

Warning

This function currently does not check the hash of the downloaded file.

Make sure to register the provider that handles the sources used in this file share before calling this function.

Parameters

fileShare	The file share object which you want to download
output	An open QIODevice that the data should be written into. In most cases, a QFile

Returns

An object that allows to track the progress of the download.

registerProvider()

template<typename ProviderType >

void QXmppFileSharingManager::registerProvider ( std::shared_ptr< ProviderType >  manager )

inline

Register a provider for automatic downloads.

Parameters

manager

A shared_ptr to a QXmppFileSharingProvider subclass The provider must define SourceType to the type of the accepted file source.

setMetadataGenerator()

void QXmppFileSharingManager::setMetadataGenerator

(

MetadataGenerator &&

generator

)

Register a function that is called when metadata needs to be gererated for a file.

The function is passed a QIODevice, so if you need the path of the file on disk, you can dynamically cast it to a QFile and access the fileName. When doing that, make sure to check the result, as in the future this function might be passed other QIODevices than QFile.

uploadFile()

std::shared_ptr< QXmppFileUpload > QXmppFileSharingManager::uploadFile	(	std::shared_ptr< QXmppFileSharingProvider >	provider,
		const QString &	filePath,
		const std::optional< QString > &	description = {}
	)

Upload a file in a way that it can be attached to a message.

Parameters

provider	The provider class decides how the file is uploaded
filePath	Path to a file that should be uploaded
description	Optional description of the file

Returns

An object that allows to track the progress of the upload. Once the upload is finished, the finished signal is emitted on it.
