[Discuss-gnuradio] Making a GUI to execute python scripts generated by GRC

[jason sam]

Hi,
I have written a python code(wxgui.py) for a simple GUI using
wxPython.There is a button in it and by pressing that button i am
executing another python file.It's working fine and i am able to call
any python file,but when i try to execute the python file created by
GRC(uhd_fft.py) i get the following error:

Form: <class 'gnuradio.wxgui.forms.forms.text_box'> ->  Error
translating value: "<__main__.MyFrame; proxy of <Swig Object of type
'wxFrame *' at 0x30f44a0> >"
    bad operand type for abs(): 'MyFrame'
    Enter a float with optional scale suffix.  E.g., 100.1M
Form: <class 'gnuradio.wxgui.forms.forms.
slider'> ->  Error translating value: "<__main__.MyFrame; proxy of
<Swig Object of type 'wxFrame *' at 0x30f44a0> >"
    unsupported operand type(s) for -: 'MyFrame' and 'float'
    Value should be within slider range

Both files are as attached.Is there any other way for it?What am i
