@J.Hilk After getting new file How to send it to server automatically?

There is also the QFileSystemWatcher which tells you when there is a change.
Follow the link given in the post above.

I didn't knwo
QFileSystemWatcher
was a thing so I'll use that.//*.h #include <QFileSystemWatcher> ... private slots: void uploadViaQNetworkManager(QString filePath){//Your upload code;} void watcherSlot(QString s); private: QFileSystemWatcher watcher; QList<QString> m_refList;
//*.cpp watcher.addPath(PathToUploadFolder); QDir dir; dir.setPath(PathToUploadFolder); if(!dir.entryList(QDir::Files).isEmpty()) for(auto &str :dir.entryList(QDir::Files | QDir::NoDotAndDotDot)){ m_refList.append( str); connect(&watcher, &QFileSystemWatcher::directoryChanged, this, &myClass::watcherSlot); void myClass::watcherSlot(QString s){ QString newfile; QDir dir; dir.setPath(s); if(!dir.entryList(QDir::Files).isEmpty()) for(int i = 0; i < m_refList.size(); i++){ bool newEntry = true;; for(newfile : dir.entryList(QDir::Files | QDir::NoDotAndDotDot)){ if(m_refList.at(i) == newfile) newEntry = false; if(newEntry){ uploadViaQNetworkManager(s+"\n"+newfile); m_refList.append(newfile); } } }
Disclaimer this is pseudo code and untested. But the prinziple should be valid
Edit: changed the filter from dirs to files.

Didn't you say in your first post that you already implemented uploading to the server?
-
@jsulm Yes I have done with Uploading Multiple files to server Now I want to implement background sync. like if any file copy in selected folder than it automatically uploaded to server. For this watcher or threading which is the best solution.....
-
@developerNancy That I understand. What I don't understand: if you're able to upload multiple files why can't you upload one? So, what exactly is the problem?
-
@jsulm I want to sync data in background it automatically uploaded when new file is added in directory no need to click again upload button.
-
@developerNancy That I understand. You already was pointed to QFileSystemWatcher, @J-Hilk even provided code. So, what is not working?
-
@jsulm which is the best approach for background sync I am Implementing thread ...
-
@J.Hilk Can you please explain How I get the Path and watcher active after button click.
-
@developerNancy you don't share any code sample with us, so it's hard to give definite working answers. You'll have to take what we write and integrate into your project.
That said I gave you a rough example how to setup and use the watcher.

How I get the Path
I don't know! How do you specify the folder for the multi file upload to the server? Just copy that path to a Qstring and give it to your
QFileSystemWatcher
