Here is the snippet: It reads the filenames in a folder and determines
new names for photo's based on the exif info.
I apreciate that threading might be a solution but the problem seems too
simple for that. Can you give an example on how to use the signal concept?
self.outFolder = QFileDialog.getExistingDirectory(
caption='Destination folder', dir=self.defOutFolder)
self.outFiles = []
if self.outFolder:
self.outFolder = self.outFolder.replace('\\', '/')
self.lineEdit_dest.setText(self.outFolder)
self.progressBar.setRange(0, self.numFiles)
for i, fname in enumerate(self.inFiles):
self.progressBar.setValue(i + 1)
newpath, newfname = rename_photo(self.inFolder, fname)
newpath = path.join(self.outFolder, newpath)
self.outFiles.append([fname, newpath, newfname])
s = fname + ' --> ' + self.outFolder + '\n'
s += path.join(newpath, newfname).replace(self.outFolder, '')
self.plainTextEdit_dest.appendPlainText(s)

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,

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
