[Qt-interest] Is there a way to process all queued events before continuing?

[André Somers]

Hi Bradley,

 

Ah
 ok
 I missed the “for the calling thread” part. Interesting; I would not
have noticed or searched that myself there. I would have assumed (I know,
never assume, always read docs) that QCoreApplication::processEvents would
work for the global event loop. Perhaps a remark in the QThread
documentation would be in order?

 

Thanks,

 

André

I'll do you one better, here's how do to it (and it's documented):

http://qt.nokia.com/doc/4.6/qcoreapplication.html#processEvents

"void QCoreApplication::processEvents ( QEventLoop::ProcessEventsFlags flags
= QEventLoop::AllEvents )   [static]

Processes all pending events for the calling thread according to the
specified flags until there are no more events to process."
