[Qt-interest] How to block until posted event is processed?

[Mihail Naydenov]

Hi, Im trying to achieve this scenario;

void doWorkFromThreadAAA()
{
    // ... work, work ...

   QApplication::postEvent( objectOnThreadBBB, new WorkFinishedEvent);

   //* NOW BLOCK UNTIL BBB HAS PROCESSED THE POSTED EVENT *//
}


I have tried two ways:
The noob one: sendEvent() - Which crashed with failed assertion about sending events across threads.
Sidenote: This is not documented!!!

The second one: 
QAbstractEventDispatcher::instance(objectOnThreadBBB->thread())->processEvents(QEventLoop::AllEvents)

This one however crashed with the very same assertion.

My question is: Is the above scenario possible (without some cross-wired wait conditions), considering that "posted events are delived when control returns to the event loop" ... can I get around this?

Thank You
