[PySide] wait for QFileDialog to close

[Sean Fisk]

Hi Janwillem,

Are you running the “lengthy part that processes a files list” within the
GUI thread? If so, you will probably see your GUI hang while this is
happening (you won’t be able to click or do anything). In this case, you
should consider running the processing in a different thread using
QThread<http://seanfisk.github.io/pyside-docs/pyside/PySide/QtCore/QThread.html>or
QThreadPool<http://seanfisk.github.io/pyside-docs/pyside/PySide/QtCore/QThreadPool.html>
.

Can you post the relevant part of the code?

Thanks,
