[Discuss-gnuradio] WX Gui Widget Error

[Mihai Chermaneanu]

Hi! 

I am a new GNU Radio user. I will be using it mainly for educational purposes.

I use a legit Windows 7 installation. ( the installation was done about 3 years ago, not a clean install). I followed step by step the instructions presented here (on the code.ettus site): http://code.ettus.com/redmine/ettus/projects/uhd/wiki/GNURadio_Windows

I am able to start GNU Radio. I'm trying to simulate a very basic situation: a signal generator, with the output connected to a throttle and the throttle's output connected to a WX Gui Widget Scope Sink (wxgui_scopesink2_0).

When i try to execute the flowgraph. The WX Gui Scope window appears but nothing happens. I am receiving the following error:

Traceback (most recent call last):
File "F:\Win7\gnuradio\lib\site-packages\gnuradio\wxgui\forms\forms.py", line 100, in <lambda>
widget.Bind(EVT_DATA, lambda x: self._update(x.data))
File "F:\Win7\gnuradio\lib\site-packages\gnuradio\wxgui\forms\forms.py", line 503, in _update
def _update(self, i): self._notebook.SetSelection(i)
File "C:\Python27\lib\site-packages\wx-2.8-msw-unicode\wx\_controls.py", line 3021, in SetSelection
return _controls_.BookCtrlBase_SetSelection(*args, **kwargs)
ValueError: in method 'BookCtrlBase_SetSelection', expected argument 2 of type 'size_t'

NOTE: I managed to see the signal in QT Gui Widget. Everything was fine. 

Why can't i use the WX Gui Widgets? ( i've tried several more like the waterfall, fft... still nothing ) 

Hope this is the right place to ask. And hope i'll know how to reply :)) 
Have a great day!
