<![CDATA[Copying a big file in a way that's interruptable and provides progress callbacks]]>Is there any standard Qt class for copying a big file so that the process can be interrupted and I can receive progress updates? Or do I have to to implement the whole thing manually with Qfile::read and QFile::write?
Perhaps, someone has already done this and there's an open source solution for this task?

Handcrafting a custom solution seems to be a better idea.

AFAIK there is nothing like this provided by Qt. It's quite a complicated matter to handle (network copy/external support/normal interruption/power outage etc...) Maybe there's something in KDE for that

Hope it helps
