@ARASHz4 said:
ok. maybe silly questions but the QNetworkReply you abort() is
the only active one?

ARASHz4

@mrjj Sorry what you mean 'only active one' ?

mrjj

@ARASHz4
Im just fishing.
Is there any chance u abort other one
than the actual download one?

ARASHz4

@mrjj no i just have one download

mrjj

@ARASHz4
Ok. abort should do it as far as I know.
Sorry. lets wait and see if someone has better ideas.

ARASHz4

mrjj

@ARASHz4

ARASHz4

Hi! Does this also happen when you replace abort() with close()? Another thing: After calling abort(), is the finished() signal emitted?

? Offline

And: On what platform do you observe this behaviour? Windows? Linux?

? Offline

BTW: In your cancelDownload() function, it says:

reply->abort();
reply = 0;

Looks like a memory leak to me.

@Wieland

hi
in

Downloader::Downloader(QUrl Url, QObject *parent) :
    QObject(parent)
{
    QNetworkRequest request(Url);
    DownloadManager.get(request);<<<<< THIS ?

    reply =  DownloadManager.get(request);

you have extra DownloadManager.get(request);
if I // it, it now drops to 0 when I abort.
Before it did not.

@mrjj DownloadManager is a private member in downloader.h

@mrjj Yes thank you now I understand
i Fix it

In my case, disconnecting all signals relating to QNetworkReply from all slots causes to abort() not works.

disconnect(m_reply, nullptr, nullptr, nullptr);

abort function works normal after commenting this line.
