[Qt-interest] BlockingQueuedConnection where and how to ?!

[Mihail Naydenov]

Hi, 
I recently encountered a case where a crash is avoided with use a BlockingQueuedConnection.
However its is the ui thread that is blocked (rapidly sending a list of user selected items to be processed by a QtConcurrent::mapped), and this is undesirable.

My question is where and how to use blocking queued instead of normal queued connection?

Thank You
