[PySide] wait for QFileDialog to close

[Janwillem van Dijk]

Hi, I have a PySide script that uses QFileDialog.getExistingDirectory(). 
After clicking the Open button the script proceeds with a lengthy part 
that processes a files list and writes to a QPlainTextEdit. 
Unfortunately the QFileDialog widget does only disappear after this 
processing is finished, hiding the QPlainTextEdit.

How can I make that the QFileDialog widget is gone before the processing 
starts?

Cheers, Janwillem
