Synchronous Http (Good reason)

[umbrella]

It's not better. It's almost the same, just that any optimizations to the loop performed by QEventLoop (if there are any) are not used by your code.[/QUOTE]

So how exactly does this work, doesn't another executing QEventLoop block the main QT event loop? Or QT manages to jump from executing one loop to another?

Thanks.

It does. That's the whole point.

Or QT manages to jump from executing one loop to another?

Look at how modal dialogs (ones triggered using QDialog::exec()) work - they use the same mechanism, they have an internal event loop.
