[Qt-interest] qtconcurrent::run() virtual member methods?

[Liam Staskawicz]

Hi - I was taking the opportunity of adding timeout functionality to the
QNetworkAccessManager api to experiment with QtConcurrent a bit.  Since
there doesn't seem to be a built-in way to specify a timeout per request, I
thought I'd run each request in a thread via QtConcurrent and call
waitForReadyRead with my appropriate timeout value.  Code looks roughly
like:

QNetworkReply* reply = netAccess.get(QNetworkRequest(url));

QFuture<bool> future = QtConcurrent::run( reply,
&QNetworkReply::waitForReadyRead, REQUEST_TIMEOUT );


but I'm getting the following compile error:


 error: no matching function for call to 'run(QNetworkReply*&, bool
(QIODevice::*)(int), int)'


just for fun, I tried passing a method defined explicitly by QNetworkReply -
::manager() - and that seemed to compile happily.  Any chance this has
something to do with the fact that waitForReadyRead is provided by
QIODevice?  The doc for QtConcurrent::run() is mostly based on a few
examples so I wasn't able to glean too much more from it.


Secondarily, any other better timeout strategies for QNetworkAccessManager
would also be welcome!

Thanks,
Liam
