problem in using QHttp

[wysota]

That's what I've done here.

Not really.

I've queued all the download requests in pendingRequestList and scheduled only one download at a time.

And that's exactly what happens - you get one download.

When the first download is finished and the request queue is empty, done(bool) signal is emitted and slot myHttpRequestDone(bool) is called where processNextRequest() is called and it's processNextRequest() where QHttp:get() is called for the next download. So it's not a problem that the condition pendingRequest.size() == 1 is executed only for the first download request.

Yeah, but after the first download you have two elements in the queue, so the condition size()==1 is not satisfied. Don't you think it should be "!pendingRequest.isEmpty()"?

When one download completes, processNextRequest() is called. So shouldn't the download for next request in pendingRequestList continue successfully?

pendingRequestList.size() == 1 condition is meant for only the first download request so that only the first download request gets chance to call processNextRequest as soon as it arrives, for other requests, they are put in the pendingRequestList. When the first download completes, QHttp::done(bool) signal is emitted and slot myHttpRequestDone(bool) gets called. At the end of myHttpRequestDone(bool) function, processNextRequest() is called and now the first request in the current list gets chance to start download by get().

This is my logic to solve the problem - downloading multiple files. But I've failed so far.

Hope I've been able to make you understand my viewpoint.
