Hello:

Working with the Dizzy build of E310 and trying to get GUI items to run  
that have no QWT in them to run.

Starting with uhd\_fft.grc (gnuradio-companion run with LD\_PRELOADS  
documented previously) with all blocks disable except QTGUI Frequency  
Sink.

This now runs until it hits

self.settings=Qt.QSettings(“GNU Radio”,“uhd\_fft”)  
self.restoreGeometry(self.settings.value(“geometry”). toByteArray()

Attribute Error: ‘QByteArray’ object has no attribute ‘toByteArray’

Commenting out this line allows that Python Program to run and properly  
display the GUI.

Looking briefly into this /usr/include/qt4/QtCore/qbytearray.h it  
doesn’t  
have any toByteArray and not being as familiar as I could be with what  
piece of code is asking for this, any pointers regarding where the root  
cause of this might be would be appreciated.

I know that there are issues with the PyQt implementation in this build  
that are being addressed, but my suspicion is that this is unrelated to  
that work.

Thanks,  
LVDJ
