[Discuss-gnuradio] QT GUI Time Sink Attribute Error

[Activecat]

Dear Sir,

How to use the block of QT GUI Time Sink?

It always produces following error message:

Generating: "/home/sgku/grc/top_block.py"

Executing: "/home/sgku/grc/top_block.py"

Traceback (most recent call last):

  File "/home/sgku/grc/top_block.py", line 158, in <module>

    tb = top_block()

  File "/home/sgku/grc/top_block.py", line 93, in __init__

    self.top_layout.addWidget(self._qtgui_time_sink_x_0_win)

  File "/usr/local/lib/python2.7/dist-packages/gnuradio/gr/top_block.py", line 94, in __getattr__

    return getattr(self._tb, name)

AttributeError: 'gr_top_block_sptr' object has no attribute 'top_layout'

>>> Done

Please advise, thanks.

Regards,
